cris: add missing declaration of kgdb_init() and breakpoint()

2011-08-04T00:25:22+00:00

Fix:

  arch/cris/arch-v10/kernel/irq.c:239: error: implicit declaration of function 'kgdb_init'
  arch/cris/arch-v10/kernel/irq.c:240: error: implicit declaration of function 'breakpoint'

Declare these two functions.

'ret' should be 'err'.

cris: fix a build error in kernel/fork.c

2011-08-04T00:25:21+00:00

Fix this error:

  kernel/fork.c:267: error: implicit declaration of function 'alloc_thread_info_node'

This is due to renaming alloc_thread_info() to alloc_thread_info_node().

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.

cris, exec: remove redundant set_fs(USER_DS)

2011-07-26T03:57:12+00:00

The address limit is already set in flush_old_exec() so those calls to
set_fs(USER_DS) are redundant.
