The current ASID allocation algorithm doesn't ensure the notification of the other CPUs when the ASID rolls over. This may lead to two processes using the same ASID (but different generation) or multiple threads of the same process using different ASIDs. This patch adds the broadcasting of the ASID rollover event to the other CPUs. To avoid a race on multiple CPUs modifying "cpu_last_asid" during the handling of the broadcast, the ASID numbering now starts at "smp_processor_id() + 1". At rollover, the cpu_last_asid will be set to NR_CPUS. Signed-off-by: NCatalin Marinas <catalin.marinas@arm.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

In preparation for perf-events support, ARM needs to support atomic64_t operations. v6k and above support the ldrexd and strexd instructions to do just that. This patch adds atomic64 support to the ARM architecture. v6k and above make use of new instructions whilst older cores fall back on the generic solution using spinlocks. If and when v7-M cores are supported by Linux, they will need to fall back on the spinlock implementation too.

The ARM setup code includes its own parser for early params, there's also one in the generic init code. This patch removes __early_init (and related code) from arch/arm/kernel/setup.c, and changes users to the generic early_init macro instead. The generic macro takes a char * argument, rather than char **, so we need to update the parser functions a little.

The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to meet its dependency. Otherwise when using "struct cpuinfo_arm" and including just 'asm/cpu.h' throws below error - arch/arm/include/asm/cpu.h:16: error: field 'cpu' has incomplete type To fix this otherway, one can also include both linux/cpu.h and asm/cpu.h but it shoudn't be that way. So this patch fixes this by including the linux/cpu.h in asm/cpu.h, so that including alone asm/cpu.h is enough.

A lot of ARM-defconfigs (those without CONFIG_ISA_DMA_API set) fail to build [1][2][3] due to the changes of the patch [PATCH] PCI: Clean up build for CONFIG_PCI_QUIRKS unset by Rafael J. Wysocki (Sat, 2 Jan 2010 22:57:24 +0100) [4] as the referenced variable 'isa_dma_bridge_buggy' in asm/dma.h is enclosed by the CONFIG_ISA_DMA_API conditional all configs without this setting fail to build. I'm not sure wether moving the condition is the right way to solve the issue, but atleast it fixes the issue :) References: [1] http://kisskb.ellerman.id.au/kisskb/buildresult/1983354/ [2] http://kisskb.ellerman.id.au/kisskb/buildresult/1983333/ [3] http://kisskb.ellerman.id.au/kisskb/buildresult/1983337/ [4] http://lkml.org/lkml/2010/1/2/102Signed-off-by: NPeter Huewe <peterhuewe@gmx.de> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Dynamically allocate the CPUFreq frequency table on OMAP2xxx chips. This fixes some compilation problems, since the kernel may not know what chip it is running on until boot-time. This also reduces the size of the CPUFreq frequency table. Problem originally reported by Felipe Balbi <felipe.balbi@nokia.com>. Thanks also for comments on the patch from Felipe and Kevin.

A subsequent patch adds code on OMAP2xxx to dynamically allocate the CPUFreq frequency table in clk_init_cpufreq_table(), so for it to avoid a leak, it will need a corresponding function to free the memory.

Commit 52650505 added an __initdata decoration to the structure containing the clk_enable and clk_disable functions. Once init data was freed, these pointers went to null, and the next enable or disable call caused the kernel to crash. This change removes this decoration.

This change adds in some missing clocks that were needed as a result of 526505... (OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c). Prior to this, it was just assumed that these clocks existed for all devices, and it was used directly instead of calling it out with a clock_get call or similar. So, not having the CK_7XX meant these clocks weren't being used anymore for omap 7xx devices, which broke things badly.

The only symbols that should be exported are symbols that are to be called from loadable kernel modules, e.g., device drivers.

Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430, we only map the IVA on OMAP2420. The memory mapping is not shared between OMAP2420 and OMAP2430, so it is inappropriate to label those macros as '24XX'; this patch changes them to '2420'.
