2010-06-02powerpc/kprobes: Remove resume_execution() in kprobesAnanth N Mavinakayanahalli
emulate_step() in kprobe_handler() would've already determined if the probed instruction can be emulated. We single-step in hardware only if the instruction couldn't be emulated. resume_execution() therefore is superfluous -- all we need is to fix up the instruction pointer after single-stepping. Thanks to Paul Mackerras for catching this. Signed-off-by: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2010-05-27rename the generic fsync implementationsChristoph Hellwig
We don't name our generic fsync implementations very well currently. The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-05-27rapidio: fix maintenance access to higher memory areasThomas Moll
Fix the maintenance access functions to farend RapidIO devices. 1. Fixed shift of the given offset, to open the maintenance window 2. Mask offset to limit access to the opened maintenance window 3. Added extended destid part to rowtear register, required for 16bit mode This method is matching maintenance transactions generation described by Freescale in the appnote AN2932. With this modification full access to a 16MB maintenance window is possible, this patch is required for IDT cps switches. For easier handling of the access routines, the access was limited to aligned memory regions. This should be no problem because all registers are 32bit wide.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

2010-05-24powerpc/kexec: Add support for FSL-BookESebastian Andrzej Siewior
This adds support kexec on FSL-BookE where the MMU can not be simply switched off. The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available.

2010-05-24powerpc/fsl-booke: fix the case where we are not in the first pageSebastian Andrzej Siewior
During boot we change the mapping a few times until we have a "defined" mapping. During this procedure a small 4KiB mapping is created and after that one a 64MiB. Currently the offset of the 4KiB page in that we run is zero because the complete startup up code is in first page which starts at RPN zero. If the code is recycled and moved to another location then its execution will fail because the start address in 64 MiB mapping is computed wrongly. It does not consider the offset to the page from the begin of the memory. This patch fixes this. Usually (system boot) r25 is zero so this does not change anything unless the code is recycled.

.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial.

This is started as swsusp_32.S modifications, but the amount of #ifdefs made the whole file horribly unreadable, so let's put the support into its own separate file. The code should be relatively easy to modify to support 44x BookEs as well, but since I don't have any 44x to test, let's confine the code to FSL BookE. (The only FSL-specific part so far is 'flush_dcache_L1'.)

2010-05-21powerpc/e500mc: Implement machine check handler.Scott Wood
Most of the MSCR bit assigments are different in e500mc versus e500, and they are now write-one-to-clear. Some e500mc machine check conditions are made recoverable (as long as they aren't stuck on), most notably L1 instruction cache parity errors.

2010-05-21powerpc: Remove unused 'protect4gb' boot parameterFUJITA Tomonori
'protect4gb' boot parameter was introduced to avoid allocating dma space acrossing 4GB boundary in 2007 (the commit 569975591c5530fdc9c7a3c45122e5e46f075a74). In 2008, the IOMMU was fixed to use the boundary_mask parameter per device properly. So 'protect4gb' workaround was removed (the 383af9525bb27f927511874f6306247ec13f1c28). But somehow I messed the 'protect4gb' boot parameter that was used to enable the workaround.

The e1000e device is becoming more common these days, so let's just build it in for pseries & ppc64_defconfig. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-05-21powerpc/pseries: Make request_ras_irqs() available to other pseries codeMark Nelson
At the moment only the RAS code uses event-sources interrupts (for EPOW events and internal errors) so request_ras_irqs() (which actually requests the event-sources interrupts) is found in ras.c and is static. We want to be able to use event-sources interrupts in other pseries code, so let's rename request_ras_irqs() to request_event_sources_irqs() and move it to event_sources.c. This will be used in an upcoming patch that adds support for IO Event interrupts that come through as event sources.

2010-05-21powerpc/numa: Use ibm,architecture-vec-5 to detect form 1 affinityAnton Blanchard
I've been told that the architected way to determine we are in form 1 affinity mode is by reading the ibm,architecture-vec-5 property which mirrors the layout of the fifth vector of the ibm,client-architecture structure. Eventually we may want to parse the ibm,architecture-vec-5 and create FW_FEATURE_* bits.
