2012-01-05ARM: 7267/1: Remove BUILD_BUG_ON from asm/bug.hSimon Glass
BUILD_BUG_ON is defined in linux/kernel.h but that is not included by the asm/bug.h header which uses it. This causes a build error: ...include/linux/mtd/map.h: In function 'inline_map_read': ...include/linux/mtd/map.h:408:3: error: implicit declaration of function 'BUILD_BUG_ON' [-Werror=implicit-function-declaration] The check is not essential and is not present for other architectures, so just remove it.

finishes successful When a request has finished successfully and we are about to call its callback, remove its pointer from the corresponding pl330_thread . This prevents the core driver from calling its callback again if pl330_release_channel() is called without first flushing the device. When pl330_update() returns, the driver is allowed to free the pointer to pl330_req so the core driver shouldn't be able to access it again.

2011-12-23ARM: 7212/1: smp_twd: reconfigure clockevents after cpufreq changeLinus Walleij
This break-out from Colin Cross' cpufreq-aware TWD patch will handle the case when our localtimer's clock changes with the cpu clock. A cpufreq transtion notifier will be registered only if the platform has supplied a specified clock to the TWD. After a cpufreq transition, update the clockevent's frequency by fetching the new clock rate from the clock framework and reprogram the next clock event. The necessary changes in the clockevents framework was done by Thomas Gleixner in kernel v3.0. ChangeLog v1->v2: - Replace IS_ERR_OR_NULL() with IS_ERR() in twd_clk check. - Update code to use the already existing per-cpu array of TWD clockevents instead of adding cruft.

The basic idea is to avoid recalibrating the rate of the clock at boot if the platform already know what rate the clock to the TWD block has. ChangeLog v1->v2: added clk_[prepare|unprepare] calls.

2011-12-23ARM: 7197/1: errata: Remove SMP dependency for erratum 751472Dave Martin
Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. This patches uses the SMP/UP patching facilities instead to compile out the workaround if the configuration means that it is definitely not needed. This means that configs for buggy silicon can simply select ARM_ERRATA_751472, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround. This seems the correct way to do things, because the erratum is a property of the silicon, irrespective of what the kernel config happens to be.

2011-12-23ARM: 7196/1: errata: Remove SMP dependency for erratum 720789Dave Martin
Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. The workaround for erratum 720789 only affects a code path which is not active in UP kernels; hence it should be safe to turn on in UP kernels, without penalty. This patch simply removes the extra dependency on SMP from Kconfig. This means that configs for buggy silicon can simply select ARM_ERRATA_720789, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround.

2011-12-19imx6q: Remove unconditional dependency on l2x0 L2 cache supportDave Martin
The i.MX6 Quad SoC will work without the l2x0 L2 cache controller support built into the kernel, so this patch removes the dependency on CACHE_L2X0. This makes the l2x0 support optional, so that it can be turned off when desired for debugging purposes etc. Since SOC_IMX6Q already depends on ARCH_IMX_V6_V7 and ARCH_IMX_V6_V7 selects MIGHT_HAVE_CACHE_L2X0, there is no need to select that option explicitly from SOC_IMX6Q.

Making CACHE_L2X0 depend on (huge list of MACH_ and ARCH_ configs) is bothersome to maintain and likely to lead to merge conflicts. This patch moves the knowledge of which platforms have a L2x0 or PL310 cache controller to the individual machines. To enable this, a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow machines to indicate that they may have such a cache controller independently of each other. Boards/SoCs which cannot reliably operate without the L2 cache controller support will need to select CACHE_L2X0 directly from their own Kconfigs instead.

2011-12-18ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtimeMarc Zyngier
sched_clock() is yet another blocker on the road to the single image. This patch implements an idea by Russell King: http://www.spinics.net/lists/linux-omap/msg49561.html Instead of asking the platform to implement both sched_clock() itself and the rollover callback, simply register a read() function, and let the ARM code care about sched_clock() itself, the conversion to ns and the rollover. sched_clock() uses this read() function as an indirection to the platform code. If the platform doesn't provide a read(), the code falls back to the jiffy counter (just like the default sched_clock). This allow some simplifications and possibly some footprint gain when multiple platforms are compiled in. Among the drawbacks, the removal of the *_fixed_sched_clock optimization which could negatively impact some platforms (sa1100, tegra, versatile and omap). Tested on 11MPCore, OMAP4 and Tegra.
