mm: clean up per architecture MM hook header files

2015-07-17T23:39:53+00:00

Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook.

As of commit 00f634bc522dedc8 ("asm-generic: add generic futex for !CONFIG_SMP") asm-generic follows the m68k futex implementation. Signed-off-by: Geert Uytterhoeven

net, lib: kill arch_fast_hash library bits

2014-12-10T20:17:46+00:00

As there are now no remaining users of arch_fast_hash(), lets kill it entirely. This basically reverts commit 71ae8aac3e19 ("lib: introduce arch optimized hash library") and follow-up work, that is f.e., commit 237217546d44 ("lib: hash: follow-up fixups for arch hash"), commit e3fec2f74f7f ("lib: Add missing arch generic-y entries for asm-generic/hash.h") and last but not least commit 6a02652df511 ("perf tools: Fix include for non x86 architectures").

irq_work: Introduce arch_irq_work_has_interrupt()

2014-09-13T16:38:07+00:00

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: Peter Zijlstra Cc: Ingo Molnar Cc: Paul E.

locking/mcs: Allow architecture specific asm files to be used for contended case

2014-02-09T20:18:52+00:00

This patch allows each architecture to add its specific assembly optimized arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for MCS lock and unlock functions.

locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order

2014-02-09T20:17:50+00:00

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: Tim Chen Cc: Arnd Bergmann Cc: Matthew R Wilcox Cc: AswinChandramouleeswaran Cc: Dave Hansen Cc: "Paul E.McKenney" Cc: Scott J Norton Cc: Will Deacon Cc: "Figo.zhang" Cc: Linus Torvalds Cc: Rik van Riel Cc: Waiman Long Cc: Peter Hurley Cc: Andrea Arcangeli Cc: Tim Chen Cc: Alex Shi Cc: Raghavendra K T Cc: Andi Kleen Cc: George Spelvin Cc: MichelLespinasse Cc: Ingo Molnar Cc: "H.
