* ARM: vfp ptrace: no point flushing hw context for PTRACE_GETVFPREGSRussell King2010-02-15
| | | | | | | | | If we're only reading the VFP context via the ptrace call, there's no need to invalidate the hardware context - we only need to do that on PTRACE_SETVFPREGS. This allows more efficient monitoring of a traced task. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: vfp: fix vfp_sync_state()Russell King2010-02-15
| | | | | | | | | | | | | | | | | | The more I look at vfp_sync_state(), the more I believe it's trying to do its job in a really obscure way. Essentially, last_VFP_context[] tracks who owns the state in the VFP hardware. If last_VFP_context[] is the context for the thread which we're interested in, then the VFP hardware has context which is not saved in the software state - so we need to bring the software state up to date. If last_VFP_context[] is for some other thread, we really don't care what state the VFP hardware is in; it doesn't contain any information pertinent to the thread we're trying to deal with - so don't touch the hardware.

* ARM: 5905/1: ARM: Global ASID allocation on SMPCatalin Marinas2010-02-15
| | | | | | | | | | | | | | | | 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: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: 5889/1: Add atomic64 routines for ARMv6k and above.Will Deacon2010-02-15
| | | | | | | | | | | | | | | 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.

* ARM: add notify_die() supportRussell King2010-02-15
| | | | | | | | | | | Kernel debuggers want to be informed of die() events, so that they can take some action to allow the problem to be inspected. Provide the hook in a similar manner to x86.

* ARM: 5880/1: arm: use generic infrastructure for early paramsJeremy Kerr2010-02-15
| | | | | | | | | | | | | | | 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.

If L2 isn't enabled in XSC3, it would enable L2. This operation is evil that would make system hang. In XSC3 core document, these words are mentioned in below. "Following reset, the L2 Unified Cache Enable bit is cleared. To enable the L2 Cache, software may set the bit to a '1' before or at the same time as enabling the MMU. Enabling the L2 Cache after the MMU has been enabled or disabling the L2 Cache after the L2 Cache has been enabled, may result in unpredictable behavior of the processor." When outer cache is initialized, the MMU is already enabled. We couldn't enable L2 after MMU enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A call to r4k_clocksource_init() was added to plat_time_init(), but when init_mips_clock_source() calls the same function, boot fails in clockevents_register_device().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the advent of function graph tracing on MIPS, Octeon needs a high precision sched_clock() implementation. Without it, most timing numbers are reported as 0.000. This new sched_clock just uses the 64-bit cycle counter appropriately scaled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 898d357b5262f9e26bc2418e01f8676e80d9867e (lmo) / 6acc7d485c24c00e111c61b2e6dff9180faebcae (kernel.org) ("Fix and enhance built-in kernel command line") arcs_cmdline[] does not contain built-in command line. The commit introduce CONFIG_CMDLINE_BOOL and CONFIG_CMDLINE_OVERRIDE to control built-in command line, and now we can use them instead of platform-specific built-in command line processing.
