All Arch: remove linkage for sys_nfsservctl system call

2011-08-26T22:09:58+00:00

The nfsservctl system call is now gone, so we should remove all
linkage for it.

atomic: cleanup asm-generic atomic*.h inclusion

2011-07-26T23:49:47+00:00

After changing all consumers of atomics to include , we
ran into some compile time errors due to this dependency chain:

linux/atomic.h
  -> asm/atomic.h
    -> asm-generic/atomic-long.h

where atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype.  This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.

Archs that need  need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).

Compile tested on i386 and x86_64 with allnoconfig.

atomic: move atomic_add_unless to generic code

2011-07-26T23:49:47+00:00

This is in preparation for more generic atomic primitives based on
__atomic_add_unless.

asm-generic: add another generic ext2 atomic bitops

2011-07-26T23:49:46+00:00

The majority of architectures implement ext2 atomic bitops as
test_and_{set,clear}_bit() without spinlock.

This adds this type of generic implementation in ext2-atomic-setbit.h and
use it wherever possible.

mn10300, exec: remove redundant set_fs(USER_DS)

2011-07-26T23:49:41+00:00

The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.

modules: make arch's use default loader hooks

2011-07-24T12:36:04+00:00

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.

MN10300: asm/uaccess.h needs to #include linux/kernel.h for might_sleep()

2011-06-22T01:31:44+00:00

MN10300's asm/uaccess.h needs to #include linux/kernel.h to get might_sleep()
otherwise it fails to build on MN10300 allyesconfig.  This fails in a few
places with messages like the following:

  In file included from security/keys/trusted.c:14:
