m32r: Add missing RCU idle APIs on idle loop

2012-10-12T20:38:55Z

commit 48ae077cfce72591b8fc80e1dcc87806f86fed7f upstream. In the old times, the whole idle task was considered as an RCU quiescent state. But as RCU became more and more successful overtime, some RCU read side critical section have been added even in the code of some architectures idle tasks, for tracing for example. So nowadays, rcu_idle_enter() and rcu_idle_exit() must be called by the architecture to tell RCU about the part in the idle loop that doesn't make use of rcu read side critical sections, typically the part that puts the CPU in low power mode. This is necessary for RCU to find the quiescent states in idle in order to complete grace periods. Add this missing pair of calls in the m32r's idle loop. Reported-by: Paul E.

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

modules: make arch's use default loader hooks

2011-07-24T12:36:04Z

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.

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.

m32r: convert cpumask api

2011-05-27T00:12:32Z

We plan to remove cpus_xx() old cpumask APIs later. Also, we plan to change mm_cpu_mask() implementation, allocate only nr_cpu_ids, thus *mm_cpu_mask() is dangerous operation. Then, this patch convert them. Signed-off-by: KOSAKI Motohiro Cc: Hirokazu Takata Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
