2009-07-30ARM: S3C: Update CPU register mapping practices.Ben Dooks

2009-07-29S3C64XX: Fix ARMCLK configurationMark Brown
The value of armclk_mask needs to be inverted for use as a mask on the register value when updating ARM_RATIO.

2009-07-29S3C64XX: Fix get_rate() for ARMCLKMark Brown
If the requested clock is faster than the parent clock then the parent clock is the closest we can get to the request so we need to return that instead of the requested clock. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-07-29S3C24XX: GPIO: Fix pin range check in s3c_gpiolib_getchipLars-Peter Clausen
In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is in the gpio banks range is reversed. Thus the function returns NULL for valid pins and the gpio chip if its not valid. As a result gpio states are not saved/restored properly during suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

2009-07-27microblaze: Makefile cleanupSam Ravnborg
Reviewed the Makefile on request by Michal and this is the resulting changes. o Use ':=' for assignmnet so we do not re-evaluate for each use o Use $(shell echo xxx) to remove "" o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS The settings are equally relevant for modules and the linked kernel o Dropped LDFLAGS_BLOB - it is no longer used o Refactored assignmnets to libs-y and core-y o Use MMU for the MMU specific extension.

2009-07-27microblaze: Get module loading workingJohn Williams
New reloc type R_MICROBLAZE_32_PCREL_LO requires a null handler (no work to do). Remove legacy hack for broken linker pre gcc-4.1.1, that required us to extract an offset from the code, add it to the addend, then rewrite the instruction. Fixup the invalid reloc type error output.

2009-07-27microblaze: Support unaligned address for put/get_user macrosMichal Simek
This patch add support for cases where load/store instruction in put/get_user macro gets unaligned pointer to data and this address is not valid. I prevent all cases which can failed. I had to disable first stage of unaligned handler which is used only for noMMU kernel and the whole work is done when interrupt is enabled. You have enable HW support for detect unaligned access in Microblaze. This patch fixed three LTP tests: getpeername01, getsockname01, socketpair01 Signed-off-by: Michal Simek <monstr@monstr.eu>
