Added the x86 implementation of word-at-a-time to the generic version, which previously only supported big-endian. Omitted the x86-specific load_unaligned_zeropad(), which in any case is also not present for the existing BE-only implementation of a word-at-a-time, and is only used under CONFIG_DCACHE_WORD_ACCESS. Added as a "generic-y" to the Kbuilds of all architectures that didn't previously have it. Signed-off-by:

As there are now no remaining users of arch_fast_hash(), lets kill it entirely. This basically reverts commit 71ae8aac ("lib: introduce arch optimized hash library") and follow-up work, that is f.e., commit 23721754 ("lib: hash: follow-up fixups for arch hash"), commit e3fec2f7 ("lib: Add missing arch generic-y entries for asm-generic/hash.h") and last but not least commit 6a02652d ("perf tools: Fix include for non x86 architectures").

The nohz full code needs irq work to trigger its own interrupt so that the subsystem can work even when the tick is stopped. Lets introduce arch_irq_work_has_interrupt() that archs can override to tell about their support for this ability. Signed-off-by:

We perform a clean up of the Kbuid files in each architecture. We order the files in each Kbuild in alphabetical order by running the below script. for i in arch/*/include/asm/Kbuild do cat $i | gawk '/^generic-y/ { i = 3; do { for (; i <= NF; i++) { if ($i == "\\") { getline; i = 1; continue; } if ($i != "") hdr[$i] = $i; } break; } while (1); next; } // { print $0; } END { n = asort(hdr); for (i = 1; i <= n; i++) print "generic-y += " hdr[i]; }' > ${i}.sorted; mv ${i}.sorted $i; done Signed-off-by:

In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by:

Blackfin arch: defines and provides entry points for certain user space functions at fixed addresses This patch defines (and provides) entry points for certain user space functions at fixed addresses. The Blackfin has no usable atomic instructions, but we can ensure that these code sequences appear atomic from a user space point of view by detecting when we're in the process of executing them during the interrupt handler return path. This allows much more efficient pthread lock implementations than the bfin_spinlock syscall we're currently using. Also provided is a small sys_rt_sigreturn stub which can be used by the signal handler setup code. The signal.c part will be committed separately. Signed-off-by:

This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by:
