microblaze: Add export.h to arch/microblaze files as required

microblaze: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW usage

2011-10-14T10:28:42Z

As far as I can tell the only reason microblaze has __ARCH_WANT_INTERRUPTS_ON_CTXSW is because it initializes new task state with interrupts enabled so that on switch_to() interrupts get enabled. So change copy_thread() to clear MSR_IE instead of set it, this will ensure switch_to() will always keep IRQs disabled. The scheduler will disable IRQs when taking rq->lock in schedule() and enable IRQs in finish_lock_switch() after its done its magic. This leaves ARM the only __ARCH_WANT_INTERRUPTS_ON_CTXSW user.

microblaze: Raise SIGFPE/FPE_INTDIV for div by zero

2011-10-14T10:24:31Z

It fixes the signal nr raised for divizion by zero from SIGILL to SIGFPE, in accordance to POSIX and other archs. This came up due to a failed test in the GCC testsuite. Signed-off-by: Edgar E. Iglesias

microblaze: Switch ELF_ARCH code to 189

2011-10-14T10:24:31Z

Switch arch code to 189, the registered code in the upstream version of binutils. Continue to accept the experimental 0xbaab. Signed-off-by: Edgar E. Iglesias Signed-off-by: Michal Simek

microblaze: Added DMA sync operations

2011-10-14T10:24:30Z

Added support gor dma_direct_sync_single_for_*() and dma_direct_sync_sg_for_*() Signed-off-by: Eli Billauer Signed-off-by: Michal Simek

microblaze: Moved __dma_sync() to dma-mapping.h

2011-10-14T10:24:29Z

__dma_sync_page() was replaced by __dma_sync(), and parameters of calls to the new function were adjusted to match __dma_sync()'s format. Signed-off-by: Eli Billauer Signed-off-by: Michal Simek

microblaze: Add PVR for Microblaze v8.20.a

2011-10-14T10:24:28Z

Microblaze v8.20.a has 0x15 version string. Signed-off-by: Michal Simek

microblaze: Clear top bit from cnt32_to_63

2011-10-14T10:24:20Z

Top bit is used as garbage and it must be clear explicitly. It is causing the problem with soft lookup code because it checks delays which are long when top bit is setup. Signed-off-by: Michal Simek

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
