All Arch: remove linkage for sys_nfsservctl system call

2011-08-26T22:09:58Z

The nfsservctl system call is now gone, so we should remove all linkage for it. Signed-off-by: NeilBrown Signed-off-by: J. Bruce Fields Signed-off-by: Linus Torvalds

mm: fix __page_to_pfn for a const struct page argument

2011-08-17T20:00:20Z

This allows the cast in lowmem_page_address (introduced as a warning fixup to 33dd4e0ec911 "mm: make some struct page's const") to be removed. Propagate const'ness to page_to_section() as well since it is required by __page_to_pfn.

asm-generic/atomic.h: allow SMP peeps to leverage this

2011-07-26T23:49:48Z

Only a few core funcs need to be implemented for SMP systems, so allow the arches to override them while getting the rest for free. At least, this is enough to allow the Blackfin SMP port to use things. Signed-off-by: Mike Frysinger Cc: Arun Sharma Cc: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

asm-generic/atomic.h: add atomic_set_mask() helper

2011-07-26T23:49:48Z

Since arches are expected to implement this guy, add a common version for people the same way as atomic_clear_mask is handled. Signed-off-by: Mike Frysinger Cc: Arun Sharma Cc: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

asm-generic/atomic.h: fix type used in atomic_clear_mask

2011-07-26T23:49:47Z

The atomic helpers are supposed to take an atomic_t pointer, not a random unsigned long pointer. So convert atomic_clear_mask over. While we're here, also add some nice documentation to the func.

asm-generic/atomic.h: simplify inc/dec test helpers

2011-07-26T23:49:47Z

We already declared inc/dec helpers, so we don't need to call the atomic_{add,sub}_return funcs directly. Signed-off-by: Mike Frysinger Cc: Arun Sharma Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

atomic: cleanup asm-generic atomic*.h inclusion

2011-07-26T23:49:47Z

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.
