This series of patches attempts to manage the pl310 erratas dynamically rather allowing platforms to choose them during build time. A bit of information which triggered the cause for this series is here: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-December/138066.html v2: - The commit 74ddcdb868a84f4a9f65e33c1ca0d24e1134e53a (l2x0: Only set .set_debug on PL310 r3p0 and earlier) which makes the assumption that non-secure platforms will implement .set_debug interface. An attempt is made to set .set_debug only if 'smc' is passed either through DT or through legacy interface (l2x0_init). With this background, this series adds 'smc' identifier to differentiate the paltforms which implements SMC interface. - Use the stashed value instead of reading RTL revision all over the place(Will) - Added l2x0_quirks to manage the errata in cpu_idle path. Tried to address Russell's comment on this, but could not completely. Because, neither I can keep the #ifdef CONFIG_PL310_ERRATA_769419 nor remove it entirely since the platform A suffers from this bug, whereas B do not but shares the same defconfig. srinidhi kasagar (5): ARM: cache-l2x0: add 'smc' identifier ARM: cache-l2x0: Manage the errata at run time ARM: make the platforms not to select the l2x0 erratas ARM: Handle l2x0 quirks in cpu_idle path ARM: mach-omap2: apply the errata at run time rather arch/arm/boot/dts/omap4.dtsi | 1 + arch/arm/include/asm/hardware/cache-l2x0.h | 16 ++++- arch/arm/kernel/process.c | 7 +- arch/arm/mach-cns3xxx/core.c | 4 +- arch/arm/mach-exynos/common.c | 4 +- arch/arm/mach-imx/Kconfig | 3 - arch/arm/mach-imx/mm-imx3.c | 4 +- arch/arm/mach-nomadik/cpu-8815.c | 4 +- arch/arm/mach-omap2/Kconfig | 2 - arch/arm/mach-omap2/omap4-common.c | 2 +- arch/arm/mach-omap2/sleep44xx.S | 25 ++++++- arch/arm/mach-realview/realview_eb.c | 4 +- arch/arm/mach-realview/realview_pb1176.c | 4 +- arch/arm/mach-realview/realview_pb11mp.c | 4 +- arch/arm/mach-realview/realview_pbx.c | 4 +- arch/arm/mach-shmobile/board-ag5evm.c | 2 +- arch/arm/mach-shmobile/board-armadillo800eva.c | 4 +- arch/arm/mach-shmobile/board-bonito.c | 4 +- arch/arm/mach-shmobile/board-kota2.c | 4 +- arch/arm/mach-shmobile/board-kzm9g.c | 4 +- arch/arm/mach-shmobile/setup-r8a7779.c | 4 +- arch/arm/mach-spear13xx/spear13xx.c | 2 +- arch/arm/mach-tegra/Kconfig | 3 - arch/arm/mach-ux500/Kconfig | 1 - arch/arm/mach-ux500/cache-l2x0.c | 2 +- arch/arm/mach-vexpress/Kconfig | 1 - arch/arm/mach-vexpress/ct-ca9x4.c | 2 +- arch/arm/mm/cache-l2x0.c | 90 +++++++++++++----------- 28 files changed, 121 insertions(+), 90 deletions(-) -- 1.7.2.dirty -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
