Pull compat time conversion changes from Peter Anvin:
"Despite the branch name this is really neither an x86 nor an
x32-specific patchset, although it the implementation of the
discussions that followed the x32 security hole a few months ago.This removes get/put_compat_timespec/val() and replaces them with
compat_get/put_timespec/val() which are savvy as to the current status
of COMPAT_USE_64BIT_TIME.It removes several unused and/or incorrect/misleading functions (like
compat_put_timeval_convert which doesn't in fact do any conversion)
and also replaces several open-coded implementations what is now
called compat_convert_timespec() with that function"* 'x86-x32-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
compat: Fix sparse address space warnings
compat: Get rid of (get|put)_compat_time(val|spec)

In order to allow the COMPAT_SYSCALL_DEFINE macro generate code that
performs proper zero and sign extension convert all 64 bit parameters
to their corresponding 32 bit compat counterparts.Signed-off-by: Heiko Carstens

Convert all compat system call functions where all parameter types
have a size of four or less than four bytes, or are pointer types
to COMPAT_SYSCALL_DEFINE.
The implicit casts within COMPAT_SYSCALL_DEFINE will perform proper
zero and sign extension to 64 bit of all parameters if needed.Signed-off-by: Heiko Carstens

We have two APIs for compatiblity timespec/val, with confusingly
similar names. compat_(get|put)_time(val|spec) *do* handle the case
where COMPAT_USE_64BIT_TIME is set, whereas
(get|put)_compat_time(val|spec) do not. This is an accident waiting
to happen.Clean it up by favoring the full-service version; the limited version
is replaced with double-underscore versions static to kernel/compat.c.A common pattern is to convert a struct timespec to kernel format in
an allocation on the user stack. Unfortunately it is open-coded in
several places. Since this allocation isn't actually needed if
COMPAT_USE_64BIT_TIME is true (since user format == kernel format)
encapsulate that whole pattern into the function
compat_convert_timespec(). An equivalent function should be written
for struct timeval if it is needed in the future.Finally, get rid of compat_(get|put)_timeval_convert(): each was only
used once, and the latter was not even doing what the function said
(no conversion actually was being done.) Moving the conversion into
compat_sys_settimeofday() itself makes the code much more similar to
sys_settimeofday() itself.v3: Remove unused compat_convert_timeval().
v2: Drop bogus "const" in the destination argument for
compat_convert_time*().Cc: Mauro Carvalho Chehab

The ipc code does not adhere the typical linux coding style.
This patch fixes lots of simple whitespace errors.- mostly autogenerated by
scripts/checkpatch.pl -f --fix \
--types=pointer_location,spacing,space_before_tab
- one manual fixup (keep structure members tab-aligned)
- removal of additional space_before_tab that were not found by --fixTested with some of my msg and sem test apps.
Andrew: Could you include it in -mm and move it towards Linus' tree?

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
