kbuild: Fix gcc -x syntax

2013-06-10T09:42:14+00:00

This is upstream commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316
backported to the 2.6.32.x stable branch.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

mips: fix build of vmlinux.lds

2009-09-25T17:49:27+00:00

Commit 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 ("arm, cris, mips,
sparc, powerpc, um, xtensa: fix build with bash 4.0") removed a few
CPPFLAGS with vital include paths necessary to build vmlinux.lds
on MIPS, and moved the calculation of the 'jiffies' symbol
directly to vmlinux.lds.S but forgot to change make ifdef/... to
cpp macros.

MIPS: make cp0 counter clocksource/event usable as fallback.

2009-01-11T09:57:26+00:00

The current mips clock build infrastructure lets a system only use
either the MIPS cp0 counter or a SoC specific timer as a clocksource /
clockevent device.

This patch renames the core cp0 counter clocksource / clockevent functions
from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to
call these renamed functions instead.

Chips which can detect whether it is safe to use a chip-specific timer
can now fall back on the cp0 counter if necessary and possible
(e.g. Alchemy with a follow-on patch).

Existing behaviour is not changed in any way.

MIPS: Hook up Cavium OCTEON in arch/mips.

2009-01-11T09:57:22+00:00

Take all the OCTEON specific files that were added, and hook them into
the build system for the arch/mips.  For versions of GCC that lack
OCTEON support, override gas target architecture.

MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processors

2008-10-27T16:18:29+00:00

We already have sufficient infrastructure to support VR5500 and VR5500A
series processors.  Here's a Makefile support to make it selectable by
ports, and enable it for NEC EMMA2RH Markeins board.

This patch also fixes a confused target help, and adds 1Gb PageMask bits
supported by VR5500 and its variants.

[MIPS] SMTC: Fix SMTC dyntick support.

2008-10-03T16:58:58+00:00

Rework of SMTC support to make it work with the new clock event system,
allowing "tickless" operation, and to make it compatible with the use of
the "wait_irqoff" idle loop.  The new clocking scheme means that the
previously optional IPI instant replay mechanism is now required, and has
been made more robust.

[MIPS] kgdb: add arch support for the kernel's kgdb core

2008-07-30T20:54:42+00:00

The new kgdb architecture specific handler registers and unregisters
dynamically for exceptions depending on when you configure a kgdb I/O
driver.

Aside from initializing the exceptions earlier in the boot process,
kgdb should have no impact on a device when it is compiled in so long
as an I/O module is not configured for use.

There have been quite a number of contributors during the existence of
this patch (see arch/mips/kernel/kgdb.c).  Most recently Jason
re-wrote the mips kgdb logic to use the die notification handlers.

[MIPS] kgdb: Remove existing implementation

2008-07-30T20:54:42+00:00

This patch explicitly removes the kgdb implementation, for mips which
is intended to be followed by a patch that adds a kgdb implementation
for MIPS that makes use of the kgdb core in the kernel.
