Tile includes a hypervisor hook to deliver messages to arbitrary
tiles, so we can use that to raise an interrupt as soon as
possible on our own core.  Unfortunately the Tilera hypervisor
disabled that support on principle in previous releases, but
it will be available in MDE 4.3.4 and later.

<title>net, lib: kill arch_fast_hash library bits</title>

<content type='text'>
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").

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.

<content type='text'>
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.

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 $i | gawk '/^generic-y/ {
                i = 3;
                do {
                        for (; i &lt;= NF; i++) {
                                if ($i == "\\") {
                                        getline;
                                        i = 1;
                                        continue;
                                }
                                if ($i != "")
                                        hdr[$i] = $i;
                        }
                        break;
                } while (1);
                next;
        }
        // {
                print $0;
        }
        END {
                n = asort(hdr);
                for (i = 1; i &lt;= n; i++)
                        print "generic-y += " hdr[i];
        }' &gt; ${i}.sorted;
        mv ${i}.sorted $i;
done

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.
