2011-10-17ARM: 7011/1: Add ARM cpu topology definitionVincent Guittot
The affinity between ARM processors is defined in the MPIDR register. We can identify which processors are in the same cluster, and which ones have performance interdependency. We can define the cpu topology of ARM platform, that is then used by sched_mc and sched_smt. The default state of sched_mc and sched_smt config is disable. When enabled, the behavior of the scheduler can be modified with sched_mc_power_savings and sched_smt_power_savings sysfs interfaces. Changes since v4 : * Remove unnecessary parentheses and blank lines Changes since v3 : * Update the format of printk message * Remove blank line Changes since v2 : * Update the commit message and some comments Changes since v1 : * Update the commit message * Add read_cpuid_mpidr in arch/arm/include/asm/cputype.h * Modify header of arch/arm/kernel/topology.c * Modify tests and manipulation of MPIDR's bitfields * Modify the place and dependancy of the config * Modify Noop functions Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-10-13ARM: switch from NO_MACH_MEMORY_H to NEED_MACH_MEMORY_HNicolas Pitre
Given that we want the default to not have any <mach/memory.h> and given that there are now fewer cases where it is still provided than the cases where it is not at this point, this makes sense to invert the logic and just identify the exception cases. The word "need" instead of "have" was chosen to construct the config symbol so not to suggest that having a mach/memory.h file is actually a feature that one should aim for.

2011-10-13ARM: mach-s3c2410: remove memory.hNicolas Pitre
This also removes the mach/s3c2400 version which was probably never used due to the fact that we have this line in arch/arm/Makefile: machine-$(CONFIG_ARCH_S3C2410) := s3c2410 s3c2400 [...] This is later used to construct the search path for: The compiler would be looking into mach-s3c2410 and picking up this version first. Any config that was actually expecting the mach-s3c2400 version was therefore producing a broken kernel binary. Not relying on any of them anymore would fix that issue.

2011-09-26ARM: prepare for removal of a bunch of <mach/memory.h> filesNicolas Pitre
When the CONFIG_NO_MACH_MEMORY_H symbol is selected by a particular machine class, the machine specific memory.h include file is no longer used and can be removed. In that case the equivalent information can be obtained dynamically at runtime by enabling CONFIG_ARM_PATCH_PHYS_VIRT or by specifying the physical memory address at kernel configuration time. If/when all instances of mach/memory.h are removed then this symbol could be removed. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

2011-09-17ARM: 7091/1: errata: D-cache line maintenance operation by MVA may not succeedWill Deacon
This patch implements a workaround for erratum 764369 affecting Cortex-A9 MPCore with two or more processors (all current revisions). Under certain timing circumstances, a data cache line maintenance operation by MVA targeting an Inner Shareable memory region may fail to proceed up to either the Point of Coherency or to the Point of Unification of the system. This workaround adds a DSB instruction before the relevant cache maintenance functions and sets a specific bit in the diagnostic control register of the SCU.
