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.

asm-generic: move archictures to common delay.h

2011-07-22T16:46:24Z

This patch moves the in-tree architectures that were using the 'generic' delay.h over to using the header file in asm-generic. This is not done using the generic-y mechanism as none of these arch's have started using that mechanism yet. This is a trivial change to make later when the arch begins using generic-y. Note the subtle change to the avr32 and SH architectures where the argument to __const_udelay was previously using the rounded down constant value instead of the rounded up value.

avr32, exec: remove redundant set_fs(USER_DS)

2011-06-14T11:38:24Z

The address limit is already set in flush_old_exec() so this set_fs(USER_DS) is redundant. Signed-off-by: Mathias Krause Signed-off-by: Hans-Christian Egtvedt

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: add #define for each of optimized find bitops

2011-05-27T00:12:38Z

The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le This adds the #define for each of the optimized find bitops in the architectures.

avr32: add ATAG_BOARDINFO

2011-04-13T13:46:59Z

The ATAG_BOARDINFO is intended to hand over the information bd->bi_board_number from u-boot to the kernel. This piece of information can be used to implement some kind of board identification while booting the kernel. Therefore it is placed in .initdata section and can be accessed via the new symbol board_number only while initializing the kernel.
