2012-03-24ARM: 7259/3: net: JIT compiler for packet filtersMircea Gherzan
Based of Matt Evans's PPC64 implementation. The compiler generates ARM instructions but interworking is supported for Thumb2 kernels. Supports both little and big endian. Unaligned loads are emitted for ARMv6+. Not all the BPF opcodes that deal with ancillary data are supported. The scratch memory of the filter lives on the stack. Hardware integer division is used if it is available. Enabled in the same way as for x86-64 and PPC64: echo 1 > /proc/sys/net/core/bpf_jit_enable A value greater than 1 enables opcode output.

2012-03-24ARM: 7334/1: add jump label supportRabin Vincent
Add the arch-specific code to support jump labels for ARM and Thumb-2. This code will only be activated on compilers that are capable of building it. It has been tested with GCC 4.6 patched with the patch from GCC bug 48637.

2012-03-24ARM: 7333/2: jump label: detect %c support for ARMRabin Vincent
Some versions of ARM GCC which do support asm goto, do not support the %c specifier. Since we need the %c to support jump labels on ARM, detect that too in the asm goto detection script to avoid build errors with these versions. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48637 Acked-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-03-24ARM: use set_current_blocked() and block_sigmask()Matt Fleming
As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check for shared signals we're about to block. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

2012-03-24ARM: 7330/1: ftrace: use canonical Thumb-2 wide instruction formatRabin Vincent
As commit 592201a9f15 (ARM: Thumb-2: Support Thumb-2 in undefined instruction handler) says: 32-bit Thumb instructions are specified in the form: ((first_half << 16 ) | second_half) which matches the layout used by the ARM ARM.

2012-03-24ARM: 7351/1: ftrace: remove useless memory checksRabin Vincent
Before replacing an instruction, the ftrace code determines what the old instruction should be and verifies that that's what's really there in memory before replacing it. This is useful if for example a bug in mcountrecord causes it to record wrong locations. However, in cases where we replace call sites in entry-common.S, these checks are not needed. For these, we currently just memcpy() the memory content and then "verify" it -- this is quite useless and can be removed.

2012-03-24ARM: 7316/1: kexec: EOI active and mask all interrupts in kexec crash pathWill Deacon
The kexec machine crash code can be called in interrupt context via a sysrq trigger made using the magic key combination. If the irq chip dealing with the serial interrupt is using the fasteoi flow handler, then we will never EOI the interrupt because the interrupt handler will be fatal. In the case of a GIC, this results in the crash kernel not receiving interrupts on that CPU interface. This patch adds code (based on the PowerPC implementation) to EOI any pending interrupts on the crash CPU before masking and disabling all interrupts. Secondary cores are not a problem since they are placed into a cpu_relax() loop via an IPI.

2012-01-23ARM: earlier initialization of vectors pageRussell King
Initialize the contents of the vectors page immediately after we allocate the page, but before we map it.

We follow this later with a flush_cache_all() after all static memory mappings have been initialized, which ensures that this is safe from any cache effects.

Add a new seqfile for reporting coherent DMA allocations. This contains the address range, size and the function which was used to allocate each region, allowing these allocations to be viewed in much the same way as /proc/vmallocinfo. The DMA coherent region has limited space, so this allows allocation failures to be viewed, as well as finding out how much space is being used.

Plus other random fixes. * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: (52 commits) acpi/apei/einj: Add extensions to EINJ from rev 5.0 of acpi spec intel_idle: Split up and provide per CPU initialization func ACPI processor: Remove unneeded variable passed by acpi_processor_hotadd_init V2 ACPI processor: Remove unneeded cpuidle_unregister_driver call intel idle: Make idle driver more robust intel_idle: Fix a cast to pointer from integer of different size warning in intel_idle ACPI: kernel-parameters.txt : Add intel_idle.max_cstate intel_idle: remove redundant local_irq_disable() call ACPI processor: Fix error path, also remove sysdev link ACPI: processor: fix acpi_get_cpuid for UP processor intel_idle: fix API misuse ACPI APEI: Convert atomicio routines ACPI: Export interfaces for ioremapping/iounmapping ACPI registers ACPI: Fix possible alignment issues with GAS 'address' references ACPI, ia64: Use SRAT table rev to use 8bit or 16/32bit PXM fields (ia64) ACPI, x86: Use SRAT table rev to use 8bit or 32bit PXM fields (x86/x86-64) ACPI: Store SRAT table revision ACPI, APEI, Resolve false conflict between ACPI NVS and APEI ACPI, Record ACPI NVS regions ACPI, APEI, EINJ, Refine the fix of resource conflict ...
2012-01-18tpm: fix (ACPI S3) suspend regressionStefan Berger
This patch fixes an (ACPI S3) suspend regression introduced in commit 68d6e6713fcb ("tpm: Introduce function to poll for result of self test") and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers active. The suspend problem occurred if the TPM was disabled and/or deactivated and therefore the TPM_PCRRead checking the result of the (asynchronous) self test returned an error code which then caused the tpm_tis driver to become inactive and this then seemed to have negatively influenced the suspend support by the tpm_infineon driver... Besides that the tpm_tis drive may stay active even if the TPM is disabled and/or deactivated. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Rafael J.

2012-01-18nvme: fix merge error due to change of 'make_request_fn' fn typeLinus Torvalds
The type of 'make_request_fn' changed in 5a7bbad27a4 ("block: remove support for bio remapping from ->make_request"), but the merge of the nvme driver didn't take that into account, and as a result the driver would compile with a warning: drivers/block/nvme.c: In function 'nvme_alloc_ns': drivers/block/nvme.c:1336:2: warning: passing argument 2 of 'blk_queue_make_request' from incompatible pointer type [enabled by default] include/linux/blkdev.h:830:13: note: expected 'void (*)(struct request_queue *, struct bio *)' but argument is of type 'int (*)(struct request_queue *, struct bio *)' It's benign, but the warning is annoying.
