Remove fs.h from mm.h

2007-07-30T00:09:29+00:00

Remove fs.h from mm.h. For this,
 1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
 2) Add back fs.h or less bloated headers (err.h) to files that need it.

As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).

Cross-compile tested without regressions on my two usual configs and (sigh):

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

[PATCH] namespaces: utsname: switch to using uts namespaces

2006-10-02T14:57:21+00:00

Replace references to system_utsname to the per-process uts namespace
where appropriate.  This includes things like uname.

Changes: Per Eric Biederman's comments, use the per-process uts namespace
	for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

[PATCH] powerpc: declare arch syscalls in

2006-03-27T03:48:22+00:00

powerpc currently declares some of its own system calls
in , but not all of them. That place also
contains remainders of the now almost unused kernel syscall
hack.

 - Add a new  with clean declarations
 - Include that file from every source that implements one
   of these
 - Get rid of old declarations in 

This patch is required as a base for implementing system
calls from an SPU, but also makes sense as a general
cleanup.

[PATCH] ppc64: fix time syscall

2006-01-09T04:47:13+00:00

ppc64 has its own version of sys_time. It looks pretty scary, touching
a whole bunch of variables without any locking or memory ordering.

In fact, a recent bugreport has shown it can actually go backwards. Time
to remove it and just use the generic sys_time, which is implemented on
top of do_gettimeofday.

[PATCH] powerpc: Fix mmap returning 64 bit addresses

2005-10-21T12:47:52+00:00

The merge of syscalls.c & sys_ppc32.c (30286ef6e044bc3d9019c3d8b900572e3fa05e65)
broke mmap, if the mmap returned a 64 bit address.

do_mmap2 was taking the return value from do_mmap_pgoff (an unsigned long), and
storing it in an int, before returning it to sys_mmap as an unsigned long. So
we were losing the high bits of the address.

You would have thought the compiler could catch this for us ...

powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpc

2005-10-18T04:19:41+00:00

This makes ppc use the syscalls.c from arch/powerpc/kernel, exports
copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc),
and consolidates the sys_fadvise64_64 implementations for 32-bit.
