Analog of what commit 494486a1 had done to alpha (another architecture with similar bug). One note: in rtrap_32.S part clr %l6 has been a rudiment of left after commit 28e61036 (sparc: Fix debugger syscall restart interactions) has killed %l6 use in there.

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.

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. For 8 bit device it reads out 5 bytes since every second byte is dummy. This optimizes bus usage and reduces number of operations and interrupts needed for one data update.

Added default output data rate setting to platform data. If default rate is 0, reset default value is used. Added control for duration via platform data. Added possibility to configure interrupts to trig on both rising and falling edge. The lis3 WU unit can be configured quite many ways and with some configurations it is quite handy to get coordinate refresh when some event trigs and when it reason goes away.

Sometimes lis3 chip seems to fail to setup factory tuning at boot up. This probably happens if there is some odd power ramp down ramp up sequence for example in device restart.

Irqcfg moved to chip data instead of platform data. This simplifies access in interrupt handler little bit. Input device open and close functions set status for interrupt threaded handler once. Unnecessary check for interrupt source removed since it is enough that active interrupt line indicates that there was an interrupt.

According to the documentation, simply reading the respective MSR isn't sufficient: It should be written with zeros, cpuid(1) be executed, and then read (see arch/x86/kernel/cpu/intel.c for an example). v2: Fail probe when microcode revision cannot be determined, but is needed to check for proper operation.

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.

exofs_new_inode() was incrementing the inode->i_count and decrementing it in create_done(), in a bad attempt to make sure the inode will still be there when the asynchronous create_done() finally arrives. This was very stupid because iput() was not called, and if it was actually needed, it would leak the inode. However all this is not needed, because at exofs_evict_inode() we already wait for create_done() by waiting for the object_created event. Therefore remove the superfluous ref counting and just Thicken the comment at exofs_evict_inode() a bit. While at it change places that open coded wait_obj_created() to call the already available wrapper.
