hexagon: Use get_signal() signal_setup_done()

2019-05-02T20:41:42+00:00

commit ac443624490f7033aefd06713e7761aee5977de3 upstream.

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.

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.

hexagon: drop _PAGE_FILE and pte_file()-related helpers

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

commit d99f95e6522db22192c331c75de182023a49fbcc 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.

hexagon: fix strncpy_from_user() error return

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

commit f35c1e0671728d1c9abc405d05ef548b5fcb2fc4 upstream.

It's -EFAULT, not -1 (and contrary to the comment in there,
__strnlen_user() can return 0 - on faults).

arch,hexagon: Convert smp_mb__*()

2014-04-18T12:20:35+00:00

Hexagon uses asm-gemeric/barrier.h and its smp_mb() is barrier().
Therefore we can use the default implementation that uses smp_mb().

include/asm/Kbuild. Remove the stale files.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

2014-04-07T23:36:11+00:00

If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally.  So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available.  I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

	$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

Hexagon: remove SP macro

2014-04-04T23:20:02+00:00

The SP/r29 macro wasn't used anywhere else and was causing conflicts
with another module, so just remove it.
