Pull gfs2 updates from Steven Whitehouse:
"The main feature of interest this time is quota updates. There are
some clean ups and some patches to use the new generic lru list code.
There is still plenty of scope for some further changes in due course -
faster lookups of quota structures is very much on the todo list.
Also, a start has been made towards the more tricky issue of using the
generic lru code with glocks, but that will have to be completed in a
subsequent merge window.
The other, more minor feature, is that there have been a number of
performance patches which relate to block allocation. In particular
they will improve performance when the disk is nearly full"

1. copy_insn() doesn't look very nice, all calculations are
confusing and it is not immediately clear why do we read
the 2nd page first.
2. The usage of inode->i_size is wrong on 32-bit machines.
3. "Instruction at end of binary" logic is simply wrong, it
doesn't handle the case when uprobe->offset > inode->i_size.
In this case "bytes" overflows, and __copy_insn() writes to
the memory outside of uprobe->arch.insn.
Yes, uprobe_register() checks i_size_read(), but this file
can be truncated after that. All i_size checks are racy, we
do this only to catch the obvious mistakes.
Change copy_insn() to call __copy_insn() in a loop, simplify
and fix the bytes/nbytes calculations.
Note: we do not care if we read extra bytes after inode->i_size
if we got the valid page. This is fine because the task gets the
same page after page-fault, and arch_uprobe_analyze_insn() can't
know how many bytes were actually read anyway.

Commit aa59c53fd459 "uprobes: Change uprobe_copy_process() to dup
xol_area" has a stupid typo, we need to setup t->utask->vaddr but
the code wrongly uses current->utask.
Even with this bug dup_xol_work() works "in practice", but only
because get_unmapped_area(NULL, TASK_SIZE - PAGE_SIZE) likely
returns the same address every time.

The commit [8fe7b65ab465: ALSA: hda - Apply GPIO setup for MacBooks
with CS4208] added a fixup entry matching with the vendor id 0x106b.
This broke the fixups for previous MBA6,1 and 6,2, since the PCI SSID
vendor id matches before evaluating the codec SSIDs.
We had a similar issue on Mac with Sigmatel codecs, and solve this
problem again similarly, by introducing a skeleton entry matching with
the all MacBooks, then remap to the right one.
