Merge branch 'setns'

* setns: ns: Wire up the setns system call Done as a merge to make it easier to fix up conflicts in arm due to addition of sendmmsg system call

ns: Wire up the setns system call

2011-05-28T17:48:39Z

32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano v3: ported to v2.6.36-rc4 by: Eric W. Biederman v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. > arch/blackfin/include/asm/unistd.h | 3 ++- > arch/blackfin/mach-common/entry.S | 1 + Acked-by: Mike Frysinger Oh - ia64 wiring looks good.

arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}

2011-05-27T00:12:38Z

By the previous style change, CONFIG_GENERIC_FIND_NEXT_BIT, CONFIG_GENERIC_FIND_BIT_LE, and CONFIG_GENERIC_FIND_LAST_BIT are not used to test for existence of find bitops anymore.

Remove unused PROC_CHANGE_PENALTY constant

2011-05-25T15:39:43Z

This constant hasn't been used since before the git era (2.6.12) and thus can be dropped.

alpha: hook up gpiolib support

2011-05-25T15:39:38Z

Allow people to use gpiolib on Alpha if they want to, mostly for build coverage. The header is a stright copy of that for Microblaze, which in turn was taken from PowerPC.

alpha: replace with new cpumask APIs

2011-05-25T15:39:38Z

We plan to remove cpu_xx() old APIs. Thus convert them. This patch has no functional change. Signed-off-by: KOSAKI Motohiro Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Matt Turner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

alpha, mm: set all online nodes in N_NORMAL_MEMORY

2011-05-25T15:39:23Z

For alpha, N_NORMAL_MEMORY represents all nodes that have present memory since it does not support HIGHMEM. This patch sets the bit at the time the node is initialized. If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it uses this nodemask to setup per-cache kmem_cache_node data structures.

extable, core_kernel_data(): Make sure all archs define _sdata

2011-05-20T06:56:56Z

A new utility function (core_kernel_data()) is used to determine if a passed in address is part of core kernel data or not. It may or may not return true for RO data, but this utility must work for RW data. Thus both _sdata and _edata must be defined and continuous, without .init sections that may later be freed and replaced by volatile memory (memory that can be freed). This utility function is used to determine if data is safe from ever being freed. Thus it should return true for all RW global data that is not in a module or has been allocated, or false otherwise. Also change core_kernel_data() back to the more precise _sdata condition and document the function.
