 "I Was Almost Tempted To Capitalise Every Word, but then I decided I
  couldn't read it myself!

  I've also got one pull request for the sti driver outstanding.  It
  relied on a commit in Greg's tree and I didn't find out in time, that
  commit is in your tree now so I might send that along once this is

9d74288ca7 GFS2: merge window
Here is a list of patches we've accumulated for GFS2 for the current upstream
 merge window. There are only six patches this time:
 
 1. A cleanup patch from Andreas to remove the gl_spin #define in favor
    of its value for the sake of clarity.
 2. A fix from Andy Price to mark the inode dirty during fallocate.
 3. A fix from Andy Price to set s_mode on mount failures to prevent
    a stack trace.
 4. A patch from me to prevent a kernel BUG() in trans_add_meta/trans_add_data
    due to uninitialized storage.
 5. A patch from me to protecting our freeing of the in-core directory
    hash table to prevent double-free.
 6. A fix for a page/block rounding problem that resulted in a metadata
    coherency problem when the block size != page size.
 
 I've got a lot more patches in various stages of review and testing,
 but I'm afraid they'll have to wait until the next merge window. So
 next time we're likely to have a lot more.

1bde925d23 fs/binfmt_elf_fdpic.c: provide NOMMU loader for regular ELF binaries
The ELF binary loader in binfmt_elf.c requires an MMU, making it
impossible to use regular ELF binaries on NOMMU archs.  However, the FDPIC
ELF loader in binfmt_elf_fdpic.c is fully capable as a loader for plain
ELF, which requires constant displacements between LOAD segments, since it
already supports FDPIC ELF files flagged as needing constant displacement.

This patch adjusts the FDPIC ELF loader to accept non-FDPIC ELF files on
NOMMU archs.  They are treated identically to FDPIC ELF files with the
constant-displacement flag bit set, except for personality, which must
match the ABI of the program being loaded; the PER_LINUX_FDPIC personality
controls how the kernel interprets function pointers passed to sigaction.

Files that do not set a stack size requirement explicitly are given a
default stack size (matching the amount of committed stack the normal ELF
loader for MMU archs would give them) rather than being rejected; this is
necessary because plain ELF files generally do not declare stack
requirements in theit program headers.

Only ET_DYN (PIE) format ELF files are supported, since loading at a fixed
virtual address is not possible on NOMMU.

This patch was developed and tested on J2 (SH2-compatible) but should
be usable immediately on all archs where binfmt_elf_fdpic is
available. Moreover, by providing dummy definitions of the
elf_check_fdpic() and elf_check_const_displacement() macros for archs
which lack an FDPIC ABI, it should be possible to enable building of
binfmt_elf_fdpic on all other NOMMU archs and thereby give them ELF
binary support, but I have not yet tested this.

The motivation for using binfmt_elf_fdpic.c rather than adapting
binfmt_elf.c to NOMMU is that the former already has all the necessary
code to work properly on NOMMU and has already received widespread
real-world use and testing. I hope this is not controversial.

I'm not really happy with having to unset the FDPIC_FUNCPTRS
personality bit when loading non-FDPIC ELF. This bit should really
reset automatically on execve, since otherwise, executing non-ELF
binaries (e.g. bFLT) from an FDPIC process will leave the personality
in the wrong state and severely break signal handling. But that's a
separate, existing bug and I don't know the right place to fix it.

349c7037b1 fs/9p: remove unnecessary new_valid_dev() checks
new_valid_dev() always returns 1, so the !new_valid_dev() check is not
needed.  Remove it.

ce1fb04153 drivers/scsi/cxgbi: fix build with EXTRA_CFLAGS
EXTRA_CFLAGS are intended to be used on the command line, not by Kbuild.
In case of cxgbi drivers, use of EXTRA_CFLAGS results in a compilation
failure:

  drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:24:21: fatal error: t4_regs.h: No such file or directory

when building like:

$ make drivers/scsi/cxgbi/ EXTRA_CFLAGS=-Wwhatever

Use ccflags-y instead of EXTRA_CFLAGS.

c8299cb605 kernel.h: make abs() work with 64-bit types
For 64-bit arguments, the abs macro casts it to an int which leads to
lost precision and may cause incorrect results.  To deal with 64-bit
types abs64 macro has been introduced but still there are places where
abs macro is used incorrectly.

To deal with the problem, expand abs macro such that it operates on s64
type when dealing with 64-bit types while still returning long when
dealing with smaller types.

This fixes one known bug (per John):

The internal clocksteering done for fine-grained error correction uses a
: logarithmic approximation, so any time adjtimex() adjusts the clock
: steering, timekeeping_freqadjust() quickly approximates the correct clock
: frequency over a series of ticks.
:
: Unfortunately, the logic in timekeeping_freqadjust(), introduced in commit
: dc491596f6 (Rework frequency adjustments to work better w/ nohz),
: used the abs() function with a s64 error value to calculate the size of
: the approximated adjustment to be made.
:
: Per include/linux/kernel.h: "abs() should not be used for 64-bit types
: (s64, u64, long long) - use abs64()".
:
: Thus on 32-bit platforms, this resulted in the clocksteering to take a
: quite dampended random walk trying to converge on the proper frequency,
: which caused the adjustments to be made much slower then intended (most
: easily observed when large adjustments are made).
