This removes 8 bytes of padding from struct cfq_queue on 64 bit builds,
shrinking it's size to 256 bytes, so fitting into 1 fewer cachelines and
allowing 1 more object/slab in it's kmem_cache.Signed-off-by: Richard Kennedy

There are several duplicate definitions in cciss_cmd.h and cciss_ioctl.h.
Consolidate these into the new cciss_defs.h file. This patch doesn't change
the definitions exposed under include/linux, so userspace apps shouldn't
be affected.Acked-by: Stephen M. Cameron

Some glibc versions intentionally create lots of alignment faults in
their gconv code, which if not fixed up, results in segfaults during
boot. This can prevent systems booting properly.There is no clear hard-configurable default for this; the desired
default depends on the nature of the userspace which is going to be
booted.So, provide a way for the alignment fault handler to be configured via
the kernel command line.Signed-off-by: Russell King

cachefiles_delete_object() can race with rename. It gets the parent directory
of the object it's asked to delete, then locks it - but rename may have changed
the object's parent between the get and the completion of the lock.However, if such a circumstance is detected, we abandon our attempt to delete
the object - since it's no longer in the index key path, it won't be seen
again by lookups of that key. The assumption is that cachefilesd may have
culled it by renaming it to the graveyard for later destruction.Signed-off-by: David Howells

The temperature and voltage limits currently set on these boards are
too conservative and will cause the driver to stop the net device
erroneously in some systems.Based on a review of the chip datasheets and advice from the designer
of these boards:- Raise the maximum board temperatures to the specified maximum ambient
temperatures for their PHYs plus the expected temperature bias of the
board
- Raise the maximum controller temperature to 90 degrees
- Lower the minimum temperatures to 0 degrees
- Widen the voltage tolerances to at least +/- 10%Signed-off-by: Ben Hutchings

The wireless sysfs methods like the rest of the networking sysfs
methods are removed with the rtnl_lock held and block until
the existing methods stop executing. So use rtnl_trylock

Signed-off-by: David S. Miller -
Yuck. It turns out that when we restart sysctls we were restarting
with the values already changed. Which unfortunately meant that
the second time through we thought there was no change and skipped
all kinds of work, despite the fact that there was indeed a change.I have fixed this the simplest way possible by restoring the changed
values when we restart the sysctl write.One of my coworkers spotted this bug when after disabling forwarding
on an interface pings were still forwarded.Signed-off-by: Eric W. Biederman

Thanks to testcase and report from Brad Spengler:
--------------------
#includetypedef int (* _wee)(void);
int main(void)
{
char buf[8] = { '\x81', '\xc7', '\xe0', '\x08', '\x81', '\xe8',
'\x00', '\x00' };
_wee wee;
printf("%p\n", &buf);
wee = (_wee)&buf;
wee();return 0;
}
--------------------TSB I-tlb load code tries to use andcc to check the _PAGE_EXEC_4U bit,
but that's bit 12 so it gets sign extended all the way up to bit 63
and the test nearly always passes as a result.Use sethi to fix the bug.

Move I2C IR initialization from just after I2C bus setup to right
before non-I2C IR initialization. This avoids the case where an I2C IR
device is blocking audio support (at least the PV951 suffers from
this). It is also more logical to group IR support together,
regardless of the connectivity.This fixes bug #15184:

…nstant => sizeof conversion.
Regression was caused by my commit 6b35ca0d3d586b8ecb8396821af21186e20afaf0
which determined message size using sizeof rather than hardcoded constants.Unfortunately pwc_set_shutter_speed reuses a 2 byte buffer for a one byte
message too so the sizeof was bogus in this case.All other uses of sizeof checked and are ok.
