The receive FIFO wakeup latency estimate in the omap-serial driver is
three orders of magnitude too small. This effectively prevents the
MPU from going to a low-power state when CONFIG_CPU_IDLE=y. This is a
major power management regression and masks some other FIFO-related
bugs in the driver.
Fix by correcting the most egregious problem in the RX wakeup latency
estimate. There are several other flaws in the estimator; these will
be fixed by a separate patch series intended for 3.4.
The difference in low-power states with this patch can be observed via
debugfs in pm_debug/count.
This estimate does not have any effect when CONFIG_CPU_IDLE=n.

Prevent OMAP UARTs from going idle while they are still transferring
data in PIO mode. This works around an oversight in the OMAP UART
hardware present in OMAP34xx and earlier: an idle UART won't send a
wakeup when the TX FIFO threshold is reached. This causes long delays
during data transmission when the MPU powerdomain enters a low-power
mode. The MPU interrupt controller is not able to respond to
interrupts when it's in a low-power state, so the TX buffer is not
refilled until another wakeup event occurs.
This fix changes the erratum i291 DMA idle workaround. Rather than
toggling between force-idle and no-idle, it will toggle between
smart-idle and no-idle. The important part of the workaround is the
no-idle part, so this shouldn't result in any change in behavior.
This fix should work on all OMAP UARTs. Future patches intended for
the 3.4 merge window will make this workaround conditional on a
"feature" flag, and will use the OMAP36xx+ TX event wakeup support.
Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291
workaround, which led to the development of this approach.

In the (default) PIO mode, use a one-byte RX FIFO threshold. The OMAP
UART IP blocks do not appear to be capable of waking the system under
an RX timeout condition. Since the previous RX FIFO threshold was 16
bytes, this meant that omap-serial.c did not become aware of any
received data until all those bytes arrived or until another UART
interrupt occurred. This made the serial console and presumably other
serial applications (GPS, serial Bluetooth) unusable or extremely
slow. A 1-byte RX FIFO threshold also allows the MPU to enter a
low-power consumption state while waiting for the FIFO to fill.
This can be verified using the serial console by comparing the
behavior when "0123456789abcde" is pasted in from another window, with
the behavior when "0123456789abcdef" is pasted in. Since the former
string is less than sixteen bytes long, the string is not echoed for
some time, while the latter string is echoed immediately.
DMA operation is unaffected by this patch.
Thanks to Russell King - ARM Linux <linux@arm.linux.org.uk> for some
additional information on the standard behavior of the RX timeout
event, which was used to improve this commit description.

_parse_integer() does one or two division instructions (which are slow)
per digit parsed to perform the overflow check.
Furthermore, these are particularly expensive examples of division
instruction as the number of clock cycles required to complete them may
go up with the position of the most significant set bit in the dividend:
if (*res > div_u64(ULLONG_MAX - val, base))
which is as maximal as possible.
Worse, on 32-bit arches, more than one of these division instructions
may be required per digit.
So, assuming we don't support a base of more than 16, skip the check if the
top nibble of the result is not set at this point.

If the number of tx/rx queues changes the ethtool ioctl
ETHTOOL_GSTATS may overrun the userspace buffer. This
occurs because the general practice in user space to
query stats is to issue a ETHTOOL_GSSET cmd to learn the
buffer size needed, allocate the buffer, then call
ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of
real_num_queues is changed or flow control attributes
are changed after ETHTOOL_GSSET but before the
ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer
overrun occurs.
To fix the overrun always return the max buffer size
needed from get_sset_count() then return all strings
and stats from get_strings()/get_ethtool_stats().
This _will_ change the output from the ioctl() call
which could break applications and script parsing in
theory. I believe these changes should not break existing
tools because the only changes will be more {tx|rx}_queues
and the {tx|rx}_pb_* stats will always be returned.
Existing scripts already need to handle changing number
of queues because this occurs today depending on system
and current features. The {tx|rx}_pb_* stats are at the
end of the output and should be handled by scripts today
regardless.
Finally get_ethtool_stats and get_strings are free-form
outputs tools parsing these outputs should be defensive
anyways. In the end these updates are better then
having a tool segfault because of a buffer overrun.

If the netdev is already in NETREG_UNREGISTERING/_UNREGISTERED state, do not
update the real num tx queues. netdev_queue_update_kobjects() is already
called via remove_queue_kobjects() at NETREG_UNREGISTERING time. So, when
upper layer driver, e.g., FCoE protocol stack is monitoring the netdev
event of NETDEV_UNREGISTER and calls back to LLD ndo_fcoe_disable() to remove
extra queues allocated for FCoE, the associated txq sysfs kobjects are already

change was made so that GRO would always have at least 16 frags available
for coalescing, but the ixgbe RSC logic was not updated. As such the RSC
feature would generate a frame larger than 64K and then overflow the value

SPI bug fixes for v3.3-rc2
Minor SPI device driver changes. A rename of the pch_spi_pcidev symbol
that merely eliminates a modpost warning, and a Kconfig change to allow
the Samsung spi driver to build on EXYNOS.
* tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6:
spi-topcliff-pch: rename pch_spi_pcidev to pch_spi_pcidev_driver
spi: Add spi-s3c64xx driver dependency on ARCH_EXYNOS4
Five fixes
* branch 'akpm':
pcmcia: fix socket refcount decrementing on each resume
mm: fix UP THP spin_is_locked BUGs
drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmax
mm: compaction: check for overlapping nodes during isolation for migration
nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments()
This fixes a memory-corrupting bug: not only does it cause the warning,
but as a result of dropping the refcount to zero, it causes the
pcmcia_socket0 device structure to be freed while it still has
references, causing slab caches corruption. A fatal oops quickly
follows this warning - often even just a 'dmesg' following the warning
causes the kernel to oops.
While testing suspend/resume on an ARM device with PCMCIA support, and a
CF card inserted, I found that after five suspend and resumes, the
kernel would complain, and shortly die after with slab corruption.

Looking at commit 7b24e79882 ("pcmcia: split up central event handler"),
the following change was made to cs.c:
return 0;
}
#endif
-
- send_event(skt, CS_EVENT_PM_RESUME, CS_EVENT_PRI_LOW);
+ if (!(skt->state & SOCKET_CARDBUS) && (skt->callback))
+ skt->callback->early_resume(skt);
return 0;
}
And the corresponding change in ds.c is from:
-static int ds_event(struct pcmcia_socket *skt, event_t event, int priority)
-{
- struct pcmcia_socket *s = pcmcia_get_socket(skt);
...
- switch (event) {
...
- case CS_EVENT_PM_RESUME:
- if (verify_cis_cache(skt) != 0) {
- dev_dbg(&skt->dev, "cis mismatch - different card\n");
- /* first, remove the card */
- ds_event(skt, CS_EVENT_CARD_REMOVAL, CS_EVENT_PRI_HIGH);
- mutex_lock(&s->ops_mutex);
- destroy_cis_cache(skt);
- kfree(skt->fake_cis);
- skt->fake_cis = NULL;
- s->functions = 0;
- mutex_unlock(&s->ops_mutex);
- /* now, add the new card */
- ds_event(skt, CS_EVENT_CARD_INSERTION,
- CS_EVENT_PRI_LOW);
- }
- break;
...
- }
- pcmcia_put_socket(s);
- return 0;
-} /* ds_event */
to:
+static int pcmcia_bus_early_resume(struct pcmcia_socket *skt)
+{
+ if (!verify_cis_cache(skt)) {
+ pcmcia_put_socket(skt);
+ return 0;
+ }
+ dev_dbg(&skt->dev, "cis mismatch - different card\n");
+ /* first, remove the card */
+ pcmcia_bus_remove(skt);
+ mutex_lock(&skt->ops_mutex);
+ destroy_cis_cache(skt);
+ kfree(skt->fake_cis);
+ skt->fake_cis = NULL;
+ skt->functions = 0;
+ mutex_unlock(&skt->ops_mutex);
+ /* now, add the new card */
+ pcmcia_bus_add(skt);
+ return 0;
+}
As can be seen, the original function called pcmcia_get_socket() and
pcmcia_put_socket() around the guts, whereas the replacement code
calls pcmcia_put_socket() only in one path. This creates an imbalance
in the refcounting.
Testing with pcmcia_put_socket() put removed shows that the bug is gone:

In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and
pltfm->als_vmax is 0. This does not make sense. I think what we want
here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV.
Both als_vmin and als_vmax local variables will be set to
pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also
remove a redundant assignment for als_vmin and als_vmax in this patch.

When isolating pages for migration, migration starts at the start of a
zone while the free scanner starts at the end of the zone. Migration
avoids entering a new zone by never going beyond the free scanned.
Unfortunately, in very rare cases nodes can overlap. When this happens,
migration isolates pages without the LRU lock held, corrupting lists
which will trigger errors in reclaim or during page free such as in the
following oops

The "X" in the taint flag means that external modules were loaded but but
is unrelated to the bug triggering. The real problem was because the PFN
layout looks like this
Zone PFN ranges:
DMA 0x00000010 -> 0x00001000
DMA32 0x00001000 -> 0x00100000
Normal 0x00100000 -> 0x01e80000
Movable zone start PFN for each node
early_node_map[14] active PFN ranges
0: 0x00000010 -> 0x0000009b
0: 0x00000100 -> 0x0007a1ec
0: 0x0007a354 -> 0x0007a379
0: 0x0007f7ff -> 0x0007f800
0: 0x00100000 -> 0x00680000
1: 0x00680000 -> 0x00e80000
0: 0x00e80000 -> 0x01080000
1: 0x01080000 -> 0x01280000
0: 0x01280000 -> 0x01480000
1: 0x01480000 -> 0x01680000
0: 0x01680000 -> 0x01880000
1: 0x01880000 -> 0x01a80000
0: 0x01a80000 -> 0x01c80000
1: 0x01c80000 -> 0x01e80000
The fix is straight-forward. isolate_migratepages() has to make a
similar check to isolate_freepage to ensure that it never isolates pages
from a zone it does not hold the LRU lock for.
This was discovered in a 3.0-based kernel but it affects 3.1.x, 3.2.x
and current mainline.

Shlomo Pongratz reported GRO L2 header check was suited for Ethernet
only, and failed on IB/ipoib traffic.
He provided a patch faking a zeroed header to let GRO aggregates frames.
Roland Dreier, Herbert Xu, and others suggested we change GRO L2 header
check to be more generic, ie not assuming L2 header is 14 bytes, but
taking into account hard_header_len.
__napi_gro_receive() has special handling for the common case (Ethernet)
to avoid a memcmp() call and use an inline optimized function instead.

Commit a0417fa3a1 ("net: Make qdisc_skb_cb upper size bound

between its header_ops.create method and its .ndo_start_xmit
method. Use this in ipoib_hard_header() to stash away the LL address
(GID + QPN), instead of the "ipoib_pseudoheader" hack. This allows
IPoIB to stop lying about its hard_header_len, which will let us fix
the L2 check for GRO.

Due to the sysdev conversion to struct device, the cpu objects get
reused when adding a cpu after offlining it, which causes a big warning

these are only there by nature of the driver being based off

In https://bugs.archlinux.org/task/27996, failure of driver r8712u is
reported, with a timeout during module loading due to synchronous loading
of the firmware. The code now uses request_firmware_nowait().

The stub_probe function can be called as soon as the stub_driver is
registered. This can lead to the busid_table_lock being used before it
is initialized. Moved calling the init_busid_table function (which
initalizes this spinlock) to be called earlier in the init function to
prevent this from happening.

When this driver was upgraded to the vendor 20100831 version in
commit 93c55dda09 et al,, one listhead initialization was missed.
This broke complete operation of the driver whenever AP mode was
enabled.

This structure is still used after it has been freed, since it
is being allocated in probe, calls to free it have been moved to
module's remove routine.
This should fix the follwoing messages when attempting to remove the
module:
drv_get_first_dev_extension: Failed to retrieve the object handle
drv_get_first_dev_extension: Failed to retrieve the object handle
drv_destroy: Failed to store DRV object
mgr_destroy: Failed to store MGR object

There are two members of pr_ctxt allocated during bridge_open that
are never freed resulting in memory leaks, these are stream_id and
node_id, they are now freed on release of the handle (bridge_release)
right before freeing pr_ctxt.
Error path for bridge_open was also fixed since the same variables
could result in memory leaking due to missing handling of failure
scenarios. While at it, the indentation changes were introduced to
avoid interleaved goto statements inside big if blocks.
