mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.
Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.
The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

Timer interrupts are excluded from being disabled during suspend. The

The mfgpt timer request its interrupt without setting the IRQF_TIMER

cifs: fix sb->s_maxbytes so that it casts properly to a signed value
This off-by-one bug causes sendfile() to not work properly. When a task
calls sendfile() on a file on a CIFS filesystem, the syscall returns -1
and sets errno to EOVERFLOW.
do_sendfile uses s_maxbytes to verify the returned offset of the file.
The problem there is that this value is cast to a signed value (loff_t).
When this is done on the s_maxbytes value that cifs uses, it becomes
negative and the comparisons against it fail.
Even though s_maxbytes is an unsigned value, it seems that it's not OK
to set it in such a way that it'll end up negative when it's cast to a
signed value. These casts happen in other codepaths besides sendfile
too, but the VFS is a little hard to follow in this area and I can't
be sure if there are other bugs that this will fix.
It's not clear to me why s_maxbytes isn't just declared as loff_t in the
first place, but either way we still need to fix these values to make
sendfile work properly. This is also an opportunity to replace the magic
bit-shift values here with the standard #defines for this.
This fixes the reproducer program I have that does a sendfile and
will probably also fix the situation where apache is serving from a
CIFS share.

ALSA: hda - Restore GPIO1 properly at resume with AD1984A
The commit
099db17e66294b02814dee01c81d9abbbeece93e introduced a
regression at suspend/resume where the GPIO1 bit isn't properly
restored, thus the speaker output gets muted initially after resume.
The fix is simple, use the cached write for storing GPIO data.

perf: avoid structure size confusion by using a fixed size
for some reason, this structure gets compiled as 36 bytes in some files
(the ones that alloacte it) but 40 bytes in others (the ones that use it).
The cause is an off_t type that gets a different size in different
compilation units for some yet-to-be-explained reason.
But the effect is disasterous; the size/offset members of the struct
are at different offsets, and result in mostly complete garbage.
The parser in perf is so robust that this all gets hidden, and after
skipping an certain amount of samples, it recovers.... so this bug
is not normally noticed.
.... except when you want every sample to be exact.
Fix this by just using an explicitly sized type.
