For power management at91_pm_enter() routine, use the cpu_do_idle() for a rock solid "wait for interrupt" implementation. For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as we can access RAM even while in self-refresh mode.

2010-10-25MN10300: Fix the PERCPU() alignment to allow for workqueuesDavid Howells
In the MN10300 arch, we occasionally see an assertion being tripped in alloc_cwqs() at the following line: /* just in case, make sure it's actually aligned */ ---> BUG_ON(!IS_ALIGNED(wq->cpu_wq.v, align)); return wq->cpu_wq.v ? 0 : -ENOMEM; The values are: wa->cpu_wq.v => 0x902776e0 align => 0x100 and align is calculated by the following: const size_t align = max_t(size_t, 1 << WORK_STRUCT_FLAG_BITS, __alignof__(unsigned long long)); This is because the pointer in question (wq->cpu_wq.v) loses some of its lower bits to control flags, and so the object it points to must be sufficiently aligned to avoid the need to use those bits for pointing to things. Currently, 4 control bits and 4 colour bits are used in normal circumstances, plus a debugging bit if debugging is set. This requires the cpu_workqueue_struct struct to be at least 256 bytes aligned (or 512 bytes aligned with debugging). PERCPU() alignment on MN13000, however, is only 32 bytes as set in vmlinux.lds.S. So we set this to PAGE_SIZE (4096) to match most other arches and stick a comment in alloc_cwqs() for anyone else who triggers the assertion.

2010-10-25svcrpc: no need for XPT_DEAD check in svc_xprt_enqueueJ. Bruce Fields
If any xprt marked DEAD is also left BUSY for the rest of its life, then the XPT_DEAD check here is superfluous--we'll get the same result from the XPT_BUSY check just after. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
2010-10-25svcrpc: assume svc_delete_xprt() called only onceJ. Bruce Fields
As long as DEAD exports are left BUSY, and svc_delete_xprt is called only with BUSY held, then svc_delete_xprt() will never be called on an xprt that is already DEAD. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
2010-10-25svcrpc: never clear XPT_BUSY on dead xprtJ. Bruce Fields
Once an xprt has been deleted, there's no reason to allow it to be enqueued--at worst, that might cause the xprt to be re-added to some global list, resulting in later corruption. Also, note this leaves us with no need for the reference-count manipulation here. Reviewed-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2010-10-25hwmon: lis3: use block read to access data registersSamu Onkalo
Add optional blockread function to interface driver. If available the chip driver uses it for data register access. For 12 bit device it reads 6 bytes to get 3*16bit data.

2010-10-25hwmon: (lis3) add axes module parameter for custom axis-mappingTakashi Iwai
The axis-mapping of lis3dev device on many (rather most) HP machines doesn't follow the standard. When each new model appears, users need to adjust again. Testing this requires the rebuild of kernel, thus it's not trivial for end-users. This patch adds a module parameter "axes" to allow a custom axis-mapping without patching and recompiling the kernel driver. User can pass the parameter such as axes=3,2,1. Also it can be changed via sysfs.
