add _IOC alternatives which are not 32/64 bit dependent (structures

Make /dev/kmem a config option; /dev/kmem is VERY rarely used, and when
used, it's generally for no good (rootkits tend to be the most common
users). With this config option, users have the choice to disable
/dev/kmem, saving some size as well.
A patch to disable /dev/kmem has been in the Fedora and RHEL kernels for
4+ years now without any known problems or legit users of /dev/kmem.

in system. So, some data structures are defined as mpc85xx_rio global, such
as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's
private members. And you can define multi RIO OF-nodes in dts file for multi
RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in

As ps3disk is a ppc64-only driver, sector_t equals to unsigned long, and the
cast is not needed.
Reuse in another (possibly 32-bit) driver is protected by the safety net called
`compiler warning' (with the cast, it may silently truncate to 32-bit).
If sector_t ever changes, we will get a compiler warning as well (with the
cast, we won't).

Buffer length handling in simulated commands is error-prone and full
of bugs. There are a number of places where necessary length checks
are missing and if the output buffer is passed in as sglist, nothing
works.
This patch adds a static buffer ata_scsi_rbuf which is sufficiently
large to handle the larges output from simulated commands (4k
currently), let all simulte functions write to the buffer and removes
all length checks as we know that there always is enough buffer space.
Copying in (for ATAPI inquiry fix up) and out are handled by
sg_copy_to/from_buffer() behind ata_scsi_rbuf_get/put() interface
which handles sglist properly.
This patch is inspired from buffer length check fix patch from Petr
Vandrovec.
Updated to use sg_copy_to/from_buffer() as suggested by FUJITA
Tomonori.

- use of C99 // comments;
- trailing whitespace;
- 'switch' and 'case' not at the same indentation level;
- no space before the open parenthesis of the 'if' and 'switch' statements;
- space between function name and open parenthesis (though I have introduced
such warnins in some places since the code looks prettier with the spaces);
- including <asm/io.h> instead of <linux/io.h>;
- line over 80 characters.
In addition to these changes, also do the following:
- make the arrays in sil_set_pio_mode() 'static', and make the arrays in
sil_set_dma_mode() 'static const';
- change the string of the 'if' statements into the 'switch' statement in
sil_pata_udma_filter();
- drop the needless '==' operators from the 'if' statements where a condition

- remove needless initializer for the 'tmp' variable in init_chipset_siimage();
- beautify groups of the variable initializers and assignment operators;
- add new line after variable definitions;
- remove new line between the comment and the statements it refers to;
- remove needless curly braces and parentheses;
- fix typos, capitalize acronyms, etc. in the comments...

Currently, affected_cpus shows which CPUs need to have their frequency
coordinated in software. When hardware coordination is in use, the contents
of this file appear the same as when no coordination is required. This can
lead to some confusion among user-space programs, for example, that do not
know that extra coordination is required to force a CPU core to a particular
speed to control power consumption.
To fix this, create a "related_cpus" attribute that always displays the
coordination map regardless of whatever coordination strategy the cpufreq
driver uses (sw or hw). If the cpufreq driver does not provide a value, fall
back to policy->cpus.

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:
- change 'au1200_ide0_' variable name prefix to the mere 'ide_';
- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
name of the chip used on the boards;
- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
on-board devices;
- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
the macros describing the Ethernet chip for consistency with the IDE
macros;
- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
indeed a shift count) in the names of the macros describing the IDE
interface.

Updated version of 4446/1. This also drops the suggested comparison
of host_remain for == 0, since that doesn't make sense (still works
for us, too). We have verified that this patch solve race problems
on atleast 2 archs at high frequencies.
(Verbatim copy of old patch text below.)
The patch below fixes a race condition in the ARM MMCI PL18x driver.
If new data arrives in the FIFO while existing data is being read then
we get a second iteration of the loop in mmci_pio_read.
However host->size is not updated until after mmci_pio_read returns,
so we get count = number of new bytes PLUS number of bytes already
copied in the first iteration. This results in a FIFO underrun as
we try and read mode data than is available.
The fix is to compensating for data read on previous iterations
when calculating the amount of data in the FIFO.

MD drivers use one printk() call to print 2 log messages and the second line
may be prefixed by a TAB character. It may also output a trailing space
before newline. klogd (I think) turns the TAB character into the 2 characters
'^I' when logging to a file. This looks ugly.
Instead of a leading TAB to indicate continuation, prefix both output lines
with 'raid:' or similar. Also remove any trailing space in the vicinity of
the affected code and consistently end the sentences with a period.

Improve write performance by preventing the delayed_list from dumping all its
stripes onto the handle_list in one shot. Delayed stripes are now further
delayed by being held on the 'hold_list'. The 'hold_list' is bypassed when:
* a STRIPE_IO_STARTED stripe is found at the head of 'handle_list'
* 'handle_list' is empty and i/o is being done to satisfy full stripe-width
write requests
* 'bypass_count' is less than 'bypass_threshold'. By default the threshold
is 1, i.e. every other stripe handled is a preread stripe provided the
top two conditions are false.
Benchmark data:
System: 2x Xeon 5150, 4x SATA, mem=1GB
Baseline: 2.6.24-rc7
Configuration: mdadm --create /dev/md0 /dev/sd[b-e] -n 4 -l 5 --assume-clean
Test1: dd if=/dev/zero of=/dev/md0 bs=1024k count=2048
* patched: +33% (stripe_cache_size = 256), +25% (stripe_cache_size = 512)
Test2: tiobench --size 2048 --numruns 5 --block 4096 --block 131072 (XFS)
* patched: +13%
* patched + preread_bypass_threshold = 0: +37%
Changes since v1:
* reduce bypass_threshold from (chunk_size / sectors_per_chunk) to (1) and
make it configurable. This defaults to fairness and modest performance
gains out of the box.
Changes since v2:
* [neilb@suse.de]: kill STRIPE_PRIO_HI and preread_needed as they are not
necessary, the important change was clearing STRIPE_DELAYED in
add_stripe_bio and this has been moved out to make_request for the hang
fix.
* [neilb@suse.de]: simplify get_priority_stripe
* [dan.j.williams@intel.com]: reset the bypass_count when ->hold_list is
sampled empty (+11%)
* [dan.j.williams@intel.com]: decrement the bypass_count at the detection
of stripes being naturally promoted off of hold_list +2%. Note, resetting
bypass_count instead of decrementing on these events yields +4% but that is
probably too aggressive.
Changes since v3:
* cosmetic fixups

The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs
All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0. Changing pixel clock has no effect
on other fbs.
Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry

required command line parameters to preallocate memory for frame buffer diufb.
optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:
Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.

Since there's no way to autodetect panel modes, we're forced to hardcode them
in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode
line (at 1200x900). This adds it to both gxfb and lxfb.
(Jordan said: We could probably detect the panel mode, but there isn't any
reason to since the panel timings are well known and won't change. While OFW
detection would be good computer science fu, it would be a wasted effort since
its so easy to hard code them into the table.)

Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some
intermediate steps between pre-existing frequencies.

Adds different wiring mode for the LCD screen.
The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead
"RGB-565". The major part of graphic stacks for embedded systems uses only
"RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping
by software (See application note AT91SAM9 LCD Controller
http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf)
This wire swapping is done on the at91sam9rl-ek board (board code
using this patch will come later).

If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.
Therefore, we should only initialize the framebuffer if we allocated it
ourselves. This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e. the user didn't provide a fixed
address or the reservation failed.
I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.

Prior to suspend, we allocate and switch to a new VT; after suspend, we switch
back to the original VT. This can be slow, and is completely unnecessary if
the framebuffer we're using can restore video properly.
This adds a hook that allows drivers to select whether or not to do this vt
switch, and changes the gxfb driver to call this hook. It also adds a module
param to gxfb to allow controlling of the vt switch (defaulting to no switch).
(Note: I'm not convinced that console_sem is the best way to protect this, but
we should probably have some form of locking..)

We want to stop sharing stuff with gx1fb; it makes little sense. There were

- Create gxfb_par (based on geodefb_par), place it in gxfb.h
- Drop display_gx.h and video_gx.h. The last few patches moved most
stuff into gxfb.h anyways, so there was very little left.
- Drop the geode_{dc,vid}_ops stuff. Un-static functions, add

This does the following in preparation for register saving:

gxfb.h.
- renames GX_* registers to match their section (ie, VP_).
- renames register bitfields to match the data sheet (ie,
DC_DCFG_TGEN -> DC_DISPLAY_CFG_TGEN).
- for DC registers, rather than defining to specific addresses, use
an enum to number them sequentially and just multiply by 4(bytes) to
access them (in read_dc/write_dc).
- for VP and FP registers, use an enum and multiple by 8 (bytes). They're
64bit registers.

Updates to the i.MX SPI controller driver:
1) Some comments changed and/or added.
2) End of transfers is now managed on TXFIFO empty interrupt after the
last write to TXFIFO. This speeds interrupt execution by removing
the wait for TXFIFO to become empty. On TXFIFO empty interrupt the
handler needs only to poll for the end of the ongoing transaction
(SPI_CONTROL_XCH) to close the transfer.
(2.1) Write only transfers are closed flushing RXFIFO.
(2.2) Read transfers are closed reading trailing bytes from RXFIFO.
(2.3) Read transfers where RXFIFO overrun occurred are closed by
flushing RXFIFO and aborting the message.
3) Fifos are now flushed via SPI disable after the end of ongoing
transaction.

Thomas Koeller had reported an issue where a device that had been making use
of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by
the backup timer test, causing the device to work improperly.
To fix this, tighten the test requirements to enable the backup timer
workaround.
The backup timer is really meant to catch UARTs that don't re-assert the THRE
interrupt. The expectation is that they do initially assert THRE. This patch
clarifies the test.

and means changing the tty<->serial interfaces so we will defer that for now.

We try and write the correct speed back but the serial midlayer already
mangles the speed on us and that means if we request B0 we report back B9600
when we should not. For now we'll hack around this in the drivers and serial

Alter the block device ->direct_access() API to work with the new
get_xip_mem() API (that requires both kaddr and pfn are returned).
Some architectures will not do the right thing in their virt_to_page() for use
by XIP (to translate from the kernel virtual address returned by
direct_access(), to a user mappable pfn in XIP's page fault handler.
However, we can't switch it to just return the pfn and not the kaddr, because
we have no good way to get a kva from a pfn, and XIP requires the kva for its
read(2) and write(2) handlers. So we have to return both.

In current kernel if we want to set the alarm time, the absolute time the
seconds relative to 1970-01-01 00:00:00) should be written into
/sys/class/rtc/rtc0/wakealarm. It is not convenient.
It is more reasonable to add the support for the alarm time relative to
current RTC time.(the unit is second)
For example:
If the RTC is required to generate alarm after 2 minutes, the following
will be OK.
echo +120 > /sys/class/rtc/rtc0/wakealarm
or echo +0x78 > /sys/class/rtc/rtc0/wakealarm

Kconfig tweaks to help reduce RTC configuration bugs, by avoiding
legacy RTC drivers when the generic RTC framework is enabled:
- If rtc-cmos is selected, disable the legacy rtc driver;
- When using generic RTC on x86, enable rtc-cmos by default;
- In the old "chardev RTC" section of Kconfig, add a comment
warning people off these (seven) legacy RTC drivers when
the generic framework is in use.
People can still use the legacy drivers if they want (or need) to.
This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver.
Ideally it would be a full list of platforms where it works, not a partial
list of ones where it won't. Or better yet, it would depend on a
"HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a
Kconfig style guideline lurking there.

Remove the code that automatically disables TTY input auditing in processes
that open TTYs when they have no other TTY open; this heuristic was
intended to automatically handle daemons, but it has false positives (e.g.
with sshd) that make it impossible to control TTY input auditing from a PAM
module. With this patch, TTY input auditing is controlled from user-space
only.
On the other hand, not even for daemons does it make sense to audit "input"
from PTY masters; this data was produced by a program writing to the PTY
slave, and does not represent data entered by the user.

This patch standardized the string auditing interfaces. No userspace
changes will be visible and this is all just cleanup and consistancy
work. We have the following string audit interfaces to use:
void audit_log_n_hex(struct audit_buffer *ab, const unsigned char *buf, size_t len);
void audit_log_n_string(struct audit_buffer *ab, const char *buf, size_t n);
void audit_log_string(struct audit_buffer *ab, const char *buf);
void audit_log_n_untrustedstring(struct audit_buffer *ab, const char *string, size_t n);
void audit_log_untrustedstring(struct audit_buffer *ab, const char *string);
This may be the first step to possibly fixing some of the issues that
people have with the string output from the kernel audit system. But we
still don't have an agreed upon solution to that problem.

Way back when, when the fc_user_scan routine was created, it kept some
of its original logic that walked the rport list and kicked off a scan.
Unfortunately, it didn't keep any of the locking around the rport list,
nor did it consider the synchronous nature of the scan invoked. The result,
there are some scan requests where the rport list changes, thus a subsequent
scan is called on a bogus rport structure and the system NMI's.

We're getting a WARN_ON from SLUB indicating that we're trying to free
caches with in-use objects. The root cause is a new dependency in the
command/sense free on unchecked_isa_dma. The WARN_ON is caused by
drivers which change this in their setup after the command/sense cache
is allocated.
The fix is to move the allocation of this cache into scsi_add_host()
so things like gdth have an opportunity to modify it between alloc and
add (but *not* after).
The true fix would be to move unchecked_isa_dma into the template and
out of the host, so it because a truly read only variable.
