* [ARM] 5231/1: Do not save the frame pointer in the csum_partial_copy_* functionsCatalin Marinas2008-09-01
| | | | | | | | | Since the other assembly functions do not seem to save the frame pointer onto the stack, this patch changes the csum_partial_copy_* functions to behave in the same way.

* [ARM] 5230/1: Replace post-indexed LDRT/STRT in uaccess.hCatalin Marinas2008-09-01
| | | | | | | | | The post-index immediate value is optional if it is 0 and this patch removes it. The reason is to allow such instructions to compile to Thumb-2 where only pre-indexed LDRT/STRT instructions are allowed.

* [ARM] 5218/1: arm: improved futex supportMikael Pettersson2008-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux/ARM currently doesn't support robust or PI futexes. The problem is that the kernel wants to perform certain ops (cmpxchg, set, add, or, andn, xor) atomically on user-space addresses, and ARM's futex.h doesn't support that. This patch adds that support, but only for uniprocessor machines. For UP it's enough to disable preemption to ensure mutual exclusion with other software agents (futexes don't need to care about other hardware agents, fortunately). This patch is based on one posted by Khem Raj on 2007-08-01 <http://marc.info/?l=linux-arm-kernel&m=118599407413016&w=2>. (That patch is included in the -RT kernel patches.) My changes since that version include: * corrected implementation of FUTEX_OP_ANDN (must complement oparg) * added missing memory clobber to futex_atomic_cmpxchg_inatomic() * removed spinlock because it's unnecessary for UP and insufficient for SMP, instead the code is restricted to UP and relies on the fact that pagefault_disable() also disables preemption * coding style cleanups Tested on ARMv5 XScales with the glibc-2.6 nptl test suite.

| | | | | | | | | | | | | | | This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code: 1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c. 2) i variable is only used when compiling for big endian. So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With gcc 4.3 and later, a pointer that has already been dereferenced is assumed not to be null since it should have caused a segmentation fault otherwise, hence any subsequent test against NULL is optimized away. Current inline asm constraint used in the implementation of prefetch() makes gcc believe that the pointer is dereferenced even though the PLD instruction does not load any data and does not cause a segmentation fault on null pointers, which causes all sorts of interesting results when reaching the end of a linked lists for example. Let's use a better constraint to properly represent the actual usage of the pointer value. Problem reported by Chris Steel.

Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap).
