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.

lib/scatterlist: clean up useless architecture versions of scatterlist.h

2014-08-08T22:57:26+00:00

There's no need to have an architecture version of scatterlist.h if the
only thing the file does is include asm-generic/scatterlist.h.  Switch to
the asm-generic versions directly.

arch: Remove stub cputime.h headers

2014-03-13T15:09:30+00:00

Many architectures have a stub cputime.h that only include the default
cputime.h

Lets remove the useless headers, we only need to mention that we want
the default headers on the Kbuild files.

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

sched, arch: Create asm/preempt.h

2013-09-25T12:07:50+00:00

In order to prepare to per-arch implementations of preempt_count move
the required bits into an asm-generic header and use this for all
archs.

tracing,x86: Add a TSC trace_clock

2012-11-13T20:48:27+00:00

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.
