2013-03-07ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) ↵Ivan Djelic
optimizations Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on assumptions about the implementation of memset and similar functions. The current ARM optimized memset code does not return the value of its first argument, as is usually expected from standard implementations. For instance in the following function: void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter) { memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter)); waiter->magic = waiter; INIT_LIST_HEAD(&waiter->list); } compiled as: 800554d0 <debug_mutex_lock_common>: 800554d0: e92d4008 push {r3, lr} 800554d4: e1a00001 mov r0, r1 800554d8: e3a02010 mov r2, #16 ; 0x10 800554dc: e3a01011 mov r1, #17 ; 0x11 800554e0: eb04426e bl 80165ea0 <memset> 800554e4: e1a03000 mov r3, r0 800554e8: e583000c str r0, [r3, #12] 800554ec: e5830000 str r0, [r3] 800554f0: e5830004 str r0, [r3, #4] 800554f4: e8bd8008 pop {r3, pc} GCC assumes memset returns the value of pointer 'waiter' in register r0; causing register/memory corruptions. This patch fixes the return value of the assembly version of memset. It adds a 'mov' instruction and merges an additional load+store into existing load/store instructions. For ease of review, here is a breakdown of the patch into 4 simple steps: Step 1 ====== Perform the following substitutions: ip -> r8, then r0 -> ip, and insert 'mov ip, r0' as the first statement of the function. At this point, we have a memset() implementation returning the proper result, but corrupting r8 on some paths (the ones that were using ip). Step 2 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 1: save r8: - str lr, [sp, #-4]! + stmfd sp!, {r8, lr} and restore r8 on both exit paths: - ldmeqfd sp!, {pc} @ Now <64 bytes to go. + ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go. (...) tst r2, #16 stmneia ip!, {r1, r3, r8, lr} - ldr lr, [sp], #4 + ldmfd sp!, {r8, lr} Step 3 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 0: save r8: - stmfd sp!, {r4-r7, lr} + stmfd sp!, {r4-r8, lr} and restore r8 on both exit paths: bgt 3b - ldmeqfd sp!, {r4-r7, pc} + ldmeqfd sp!, {r4-r8, pc} (...) tst r2, #16 stmneia ip!, {r4-r7} - ldmfd sp!, {r4-r7, lr} + ldmfd sp!, {r4-r8, lr} Step 4 ====== Rewrite register list "r4-r7, r8" as "r4-r8".

2013-03-06ARM: 7666/1: decompressor: add -mno-single-pic-base for building the ↵Jonathan Austin
decompressor Before jumping to (position independent) C-code from the decompressor's assembler world we set-up the C environment. This setup currently does not set r9, which for arm-none-uclinux-uclibceabi toolchains is by default expected to be the PIC offset base register (IE should point to the beginning of the GOT). Currently, therefore, in order to build working kernels that use the decompressor it is necessary to use an arm-linux-gnueabi toolchain, or similar. uClinux toolchains cause a prefetch abort to occur at the beginning of the decompress_kernel function. This patch allows uClinux toolchains to build bootable zImages by forcing the -mno-single-pic-base option, which ensures that the location of the GOT is re-derived each time it is required, and r9 becomes free for use as a general purpose register. This has a small (4% in instruction terms) advantage over the alternative of setting r9 to point to the GOT before calling into the C-world.

2013-03-03ARM: 7661/1: mm: perform explicit branch predictor maintenance when requiredWill Deacon
The ARM ARM requires branch predictor maintenance if, for a given ASID, the instructions at a specific virtual address appear to change. From the kernel's point of view, that means: - Changing the kernel's view of memory (e.g. switching to the identity map) - ASID rollover (since ASIDs will be re-allocated to new tasks) This patch adds explicit branch predictor maintenance when either of the two conditions above are met.

2013-03-03ARM: 7660/1: tlb: add branch predictor maintenance operationsWill Deacon
The ARM architecture requires explicit branch predictor maintenance when updating an instruction stream for a given virtual address. In reality, this isn't so much of a burden because the branch predictor is flushed during the cache maintenance required to make the new instructions visible to the I-side of the processor. However, there are still some cases where explicit flushing is required, so add a local_bp_flush_all operation to deal with this.

2013-03-03ARM: 7659/1: mm: make mm->context.id an atomic64_t variableWill Deacon
mm->context.id is updated under asid_lock when a new ASID is allocated to an mm_struct. However, it is also read without the lock when a task is being scheduled and checking whether or not the current ASID generation is up-to-date. If two threads of the same process are being scheduled in parallel and the bottom bits of the generation in their mm->context.id match the current generation (that is, the mm_struct has not been used for ~2^24 rollovers) then the non-atomic, lockless access to mm->context.id may yield the incorrect ASID. This patch fixes this issue by making mm->context.id and atomic64_t, ensuring that the generation is always read consistently. For code that only requires access to the ASID bits (e.g. TLB flushing by mm), then the value is accessed directly, which GCC converts to an ldrb.

2013-03-03ARM: 7658/1: mm: fix race updating mm->context.id on ASID rolloverWill Deacon
If a thread triggers an ASID rollover, other threads of the same process must be made to wait until the mm->context.id for the shared mm_struct has been updated to new generation and associated book-keeping (e.g. TLB invalidation) has ben performed. However, there is a *tiny* window where both mm->context.id and the relevant active_asids entry are updated to the new generation, but the TLB flush has not been performed, which could allow another thread to return to userspace with a dirty TLB, potentially leading to data corruption. In reality this will never occur because one CPU would need to perform a context-switch in the time it takes another to do a couple of atomic test/set operations but we should plug the race anyway. This patch moves the active_asids update until after the potential TLB flush on context-switch.

Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches.

2013-02-28arm: mvebu: Add support for SPI controller in Armada 370/XPEzequiel Garcia
The Armada 370 and Armada XP SoC has an SPI controller. This patch adds support for this controller in Armada 370 and Armada XP SoC common device tree files. Note that the Armada XP SPI register length is 0x50 bytes, while Armada 370 SPI register length is 0x28 bytes, so we choose the smaller of the two.
