292cf4a8a9 tpm: work around bug in Broadcom BCM0102 chipset
Patch tpm-correct-tpm-timeouts-to-jiffies-conversion reveals a bug in the
Broadcom BCM0102 TPM chipset used in the Dell Latitude D820 - although
most of the timeouts are returned in usecs as per the spec, one is
apparently returned in msecs, which results in a too-small value leading
to a timeout when the code treats it as usecs.  To prevent a regression,
we check for the known too-short value and adjust it to a value that makes
things work.

9e5b1b1222 tpm: correct tpm timeouts to jiffies conversion
This patch fixes timeouts conversion to jiffies, by replacing
msecs_to_jiffies() calls with usecs_to_jiffies().  According to TCG TPM
Specification Version 1.2 Revision 103 (pages 166, 167) TPM timeouts and
durations are returned in microseconds (usec) not in miliseconds (msec).

This fixes a long hang while loading TPM driver, if TPM chip starts in
"Idle" state instead of "Ready" state.  Without this patch - 'modprobe'
may hang for 30 seconds or more.

0f4d3fd8ac legacy rtc: remove needless/confusing HPET_RTC_IRQ option
HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more
correct.  (http://bugzilla.kernel.org/show_bug.cgi?id=11111)

Note that when using the legacy RTC driver, platforms don't really do a
dynamic switch between HPET and non-HPET modes based on whether HPET
hardware actually exists ...  only rtc-cmos (using the new RTC framework)
currently switches that way.

So this reflects bitrot in that legacy code, for x86/ia64: kernels with
HPET support configured (e.g.  for a clocksource) can't get IRQs from the
legacy RTC driver unless they really have HPET hardware.  (The obvious
workaround is to not use the legacy RTC driver on those platforms when you
configure HPET ...  unless you know the target really has a HPET.)

82e14a6215 agp: Fix stolen memory counting on G4X.
On the GM45, the amount of stolen memory mapped to the GTT was underestimated,
even though we had 508KB more available since the GTT doesn't take from
stolen memory. On the non-GM45 G4X, we overestimated how much stolen was
mapped to the GTT by 4KB, resulting in GPU page faults when that page was
accessed.

This update requires a corresponding update to xf86-video-intel to work
correctly.

commit 611e097d77
    Author: Christian Borntraeger <borntraeger@de.ibm.com>
    hvc_console: rework setup to replace irq functions with callbacks
    introduced a spinlock recursion problem. The notifier_del is
    called with a lock held, and in turns calls free_irq which then
    complains when manipulating procfs. This fixes it by moving the
    call to the notifier to outside of the locked section.

Pass-in 'inode' or 'tty' parameter to devpts interfaces.  With multiple

to identify the instance of devpts mounted. The parameters also help

Changelog[v3]:
	- minor changes due to merge with ttydev updates
	- rename parameters to emphasize they are ptmx or pts inodes
	- pass-in tty_struct * to devpts_pty_kill() (this will help

feebed6515 tty: shutdown method
Right now there are various drivers that try to use tty->count to know when
they get the final close. Aristeau Rozanski showed while debugging the vt
sysfs race that this isn't entirely safe.

Instead of driver side tricks to work around this introduce a shutdown which
is called when the tty is being destructed. This also means that the shutdown
method is tied into the refcounting.

Use this to rework the console close/sysfs logic.

Remove lots of special case code from the tty core code. The pty code can now
have a shutdown() method that replaces the special case hackery in the tree

Data read from a TTY can contain an embedded NUL byte (e.g. after

This patch modifies the AUDIT_TTY record to always use the hexadecimal
format, which does not terminate at the first NUL byte.  The vast
majority of recorded TTY input data will contain either ' ' or '\n', so
the hexadecimal format would have been used anyway.

2571cd6a8e drivers/char/hvc_console.c: adjust call to put_tty_driver
The call to put_tty_driver is out of place and is applied to the wrong
argument.

The function enclosing the patched code calls alloc_tty_driver and stores
the result in drv.  Subsequently, there are two occurrences of error
handling code, one making a goto to put_tty and one making a goto to
stop_thread.  At the point of the first one the assignment hvc_driver = drv
has not yet been executed, and from inspecting the rest of the file it
seems that hvc_driver would be NULL.  Thus the current call to
put_tty_driver is useless, and one applied to drv is needed.  The goto
stop_thread is in the error handling code for a call to
tty_register_driver, but the error cases in tty_register_driver do not free
its argument, so it should be done here.  Thus, I have moved the put_tty
label after the stop_thread label, so that put_tty_driver is called in both
cases.

The semantic match that finds this problem is as follows:

4bdec11f56 As pointed out by Jonathan Corbet, the timer must be deleted before
flushing the work queue in order to avoid a job being submitted after the
chip had been released.

253115b71f The tpm_dev_release function is only called for platform devices, not pnp
devices, so we implemented the .remove function for pnp ones.  Since it's
code is very similar to the one inside tpm_dev_release, we've created a
helper function tpm_dev_vendor_release, which is called by both.

f26ed116c0 HPET: Remove spurious HPET busy warning message.
On x86 systems with CONFIG_HPET_TIMER enabled, when
the HPET driver (drivers/char/hpet.c) is loaded,
an incorrect busy message is printed when the driver
initializes since the HPET has already been allocated
by the core timer code. Remove the warning message.
