MIPS: kernel: syscall: Set the appropriate ISA level for MIPS R6

2015-02-17T15:37:29Z

MIPS R6 changed the opcodes for LL/SC instructions so we need to set the appropriate ISA level. Cc: Matthew Fortune Signed-off-by: Markos Chandras

MIPS: Apply `.insn' to fixup labels throughout

2014-11-24T06:45:36Z

Fix the issue with the ISA bit being lost in fixups that jump to labels placed just before a section switch. Such a switch leads to the ISA bit being lost, because GAS concludes there is no code that follows and therefore the label refers to data. Use the `.insn' pseudo-op to convince the tool this is not the case. This lack of label annotation leads to microMIPS compilation errors like: mips-linux-gnu-ld: arch/mips/built-in.o: .fixup+0x3b8: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. mips-linux-gnu-ld: final link failed: Bad value Signed-off-by: Maciej W.

MIPS: Fix gigaton of warning building with microMIPS.

2014-03-31T16:17:12Z

With binutils 2.24 the attempt to switch with microMIPS mode to MIPS III mode through .set mips3 results in *lots* of warnings like {standard input}: Assembler messages: {standard input}:397: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension during a kernel build. Fixed by using .set arch=r4000 instead. This breaks support for building the kernel with binutils 2.13 which was supported for 32 bit kernels only anyway and 2.14 which was a bad vintage for MIPS anyway. Signed-off-by: Ralf Baechle

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2013-03-02T15:44:16Z

Pull MIPS updates from Ralf Baechle: o Add basic support for the Mediatek/Ralink Wireless SoC family. o The Qualcomm Atheros platform is extended by support for the new QCA955X SoC series as well as a bunch of patches that get the code ready for OF support. o Lantiq and BCM47XX platform have a few improvements and bug fixes. o MIPS has sent a few patches that get the kernel ready for the upcoming microMIPS support. o The rest of the series is made up of small bug fixes and cleanups that relate to various parts of the MIPS code. The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/. Fix up silly conflicts, mostly due to whitespace cleanups. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (105 commits) MIPS: Quit exporting kernel internel break codes to uapi/asm/break.h MIPS: remove broken conditional inside vpe loader code MIPS: SMTC: fix implicit declaration of set_vi_handler MIPS: early_printk: drop __init annotations MIPS: Probe for and report hardware virtualization support.

mips: switch to generic sys_fork() and sys_clone()

2013-02-03T23:33:02Z

we still need the wrappers to store callee-saved registers in pt_regs, but once that done we can jump to kernel/fork.c variants. Signed-off-by: Al Viro

MIPS: Whitespace cleanup.

2013-02-01T09:00:22Z

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle
