Make asm/word-at-a-time.h available on all architectures

2018-10-21T07:46:11+00:00

commit a6e2f029ae34f41adb6ae3812c32c5d326e1abd2 upstream.

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.

frv: drop _PAGE_FILE and pte_file()-related helpers

2018-10-03T03:09:54+00:00

commit ca5bfa7b390017f053d7581bc701518b87bc3d43 upstream.

We've replaced remap_file_pages(2) implementation with emulation.  Nobody
creates non-linear mapping anymore.

This patch also increase number of bits availble for swap offset.

frv: fix clear_user()

2016-11-20T01:17:27+00:00

commit 3b8767a8f00cc6538ba6b1cf0f88502e2fd2eb90 upstream.

It should check access_ok().  Otherwise a bunch of places turn into
trivially exploitable rootholes.

sys_sgetmask/sys_ssetmask: add CONFIG_SGETMASK_SYSCALL

2014-06-04T23:54:14+00:00

sys_sgetmask and sys_ssetmask are obsolete system calls no longer
supported in libc.

This patch replaces architecture related __ARCH_WANT_SYS_SGETMAX by expert
mode configuration.That option is enabled by default for those
architectures.

 "The main changes in this cycle were:

   - reduced/streamlined smp_mb__*() interface that allows more usecases
     and makes the existing ones less buggy, especially in rarer
     architectures

   - add rwsem implementation comments

   - bump up lockdep limits"

PCI: Turn pcibios_penalize_isa_irq() into a weak function

2014-05-27T22:23:58+00:00

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures.  Make pcibios_penalize_isa_irq() a
__weak function to simplify the code.  This removes the need for new
platforms to add stub implementations of pcibios_penalize_isa_irq().

arch,frv: Convert smp_mb__*()

2014-04-18T12:20:34+00:00

Because:

arch/frv/include/asm/smp.h:#error SMP not supported

smp_mb() is barrier() and we can use the default implementation that
uses smp_mb().

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;
