2014-05-28MIPS: defconfigs: add MTD_SPI_NOR (new dependency for M25P80)Brian Norris
These defconfigs contain the CONFIG_M25P80 symbol, which is now dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to satisfy the new dependency. At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

2014-05-28MIPS: Add __SANE_USERSPACE_TYPES__ to asm/types.h for LL64Aaro Koskinen
Allow 64-bit userspace programs to use ll64 types. The define name comes from commit 2c9c6ce0199a4d252e20c531cfdc9d24e39235c0 (powerpc: Add __SANE_USERSPACE_TYPES__ to asm/types.h for LL64). The patch allows to compile perf on MIPS64 and eliminates the following warnings: tests/attr.c:74:4: error: format '%llu' expects argument of type 'long long unsigned int', but argument 6 has type '__u64' [-Werror=format=] Signed-off-by: Aaro Koskinen <aaro.koskinen@nsn.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/6890/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2014-05-28MIPS: Lemote 2F: cs5536: mfgpt: depend on !highresSebastian Andrzej Siewior
This timer does not support oneshot mode and as such the system remains in periodic mode and won't support high res timers. This patch adds a note about this in Kconfig and lets it depend on !highres so users which want to use high timers don' stuck with this timer.

2014-05-26MIPS: DTS: Fix missing device_type="memory" property in memory nodesLeif Lindholm
A few platforms lack a 'device_type = "memory"' for their memory nodes, relying on an old ppc quirk in order to discover its memory.

2014-05-26MIPS: SEAD3: Introduce the use of the managed version of kzallocHimangi Saraogi
This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. Also, the now unnecessary labels out_mem and out are done away with. The error handling code is moved under if and return 0 is now at the end of the function. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Tested-by: Markos Chandras <markos.chandras@imgtec.com> Reviewed-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/6977/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2014-05-24MIPS: MT: Remove SMTC supportRalf Baechle
Nobody is maintaining SMTC anymore and there also seems to be no userbase. Which is a pity - the SMTC technology primarily developed by Kevin D. Kissell <kevink@paralogos.com> is an ingenious demonstration for the MT ASE's power and elegance. Based on Markos Chandras <Markos.Chandras@imgtec.com> patch https://patchwork.linux-mips.org/patch/6719/ which while very similar did no longer apply cleanly when I tried to merge it plus some additional post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to merge once upon a time.

There are two checks for CONFIG_SIBYTE_BCM1480_PROF in the tree since v2.6.15. The related Kconfig symbol has never been added to the tree. So these checks have always evaluated to false.

2014-05-23MIPS: math-emu: Switch to using the MIPS rounding modes.Ralf Baechle

2014-05-23MIPS: Sort out mm_isBranchInstr.Ralf Baechle
mm_isBranchInstr() did reside in the math emu code even though it logically is separate and also is used outside the math emu code. In addition GCC 4.9.0 leaves the following unnnecessarily bloated function body for a non-microMIPS configuration: <mm_isBranchInstr>: 105c: afa50004 sw a1,4(sp) 1060: afa60008 sw a2,8(sp) 1064: afa7000c sw a3,12(sp) 1068: 03e00008 jr ra 106c: 00001021 move v0,zero which stores arguments that are never going to be used on the stack frame. Move mm_isBranchInstr() from cp1emu.c to branch.c, then split mm_isBranchInstr() into a __mm_isBranchInstr() core and a mm_isBranchInstr() wrapper inline function which only invokes __mm_isBranchInstr() on microMIPS configurations. This shaves off 112 bytes off the kernel and improves code flow a bit. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
