2012-01-05ARM: restart: at91: use new restart hookRussell King
Rather than using a private function pointer, use the existing arm_pm_restart function pointer instead. We no longer need to enable the I-cache in at91sam9_alt_reset() as the caches will now be on when this function is called. Update the function names to use the 'restart' terminology rather than the 'reboot' terminology. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-05ARM: restart: remove s3c24xx restart handlerRussell King
Remove the s3c24xx restart handler, which is trying to work around a chip bug by keeping caches on but flushed. As we now only disable caches when performing a soft reboot, there doesn't need to be a work-around to do that.

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.

Following is happened when CONFIG_CPU_FREQ_S3C24XX_DEBUGFS is selected without building of s3c2410-iotiming.c file: arch/arm/mach-s3c2440/built-in.o:(.data+0x38c): undefined reference to `s3c2410_iotiming_debugfs Basically, the CONFIG_S3C2410_IOTIMING is not selected for MACH_MINI2440. Because the s3c2410-iotiming.c is not ever compiled and enabling CONFIG_CPU_FREQ_S3C24XX_DEBUGFS option caused undefined reference to s3c2410_iotiming_debugfs() defined in that file.

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.

2011-12-23ARM: 7211/1: smp_twd: get the rate from a clockLinus Walleij
This break-out from Colin Cross' cpufreq-aware TWD patch will optionally retrieve the clock rate of the TWD from an external clock. A variant of this patch has been proposed by Rob Herring as well. 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.
