In arch_setup_msi_irq(), there is no case for PCIe2. So board which have PCIe2 functionality fails to boot with "Kernel panic - not syncing: arch_setup_msi_irq: Invalid octeon_dma_bar_type" message. This patch solve this problem.

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.

Allow 64-bit userspace programs to use ll64 types. The define name comes from commit 2c9c6ce0 (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>

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.

Nothing was using the method and there isn't any need for this hook. This leaves smp_cpus_done() empty for the moment. As suggested by Paul Bolle <pebolle@tiscali.nl>. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

A few platforms lack a 'device_type = "memory"' for their memory nodes, relying on an old ppc quirk in order to discover its memory. Add the missing data so that all parsing code can find memory nodes correctly.

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>

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. Besides, one of these checks guards a call of sbprof_cpu_intr(). But that function is not defined. Remove all this.

Previously math-emu was using the IEEE-754 constants internally. These were differing by having the constants for rounding to +/- infinity switched, so a conversion was necessary. This would be entirely avoidable if the MIPS constants were used throughout, so get rid of the bloat. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

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>
