2010-02-18ARM: 5938/1: ARM: L2: export outer_cache_fnsSantosh Shilimkar
The 'outer_cache' variable is needed by the outer_inv_range(), outer_clean_range() and outer_flush_range() functions, which are declared as inline in asm/cacheflush.h. Otherwise drivers built as a loadable module, which access these functions, will have an undefined symbol.

2010-02-18OMAP: DSS2: remove sub-panel systemTomi Valkeinen
The system to allow panel drivers to exists as attached to ctrl drivers did never work very well. It is not useed, and this patch removes it to make the driver cleaner. For now, controller drivers need to include also the panel driver code. In the future a proper mechanism for this should be developed, perhaps by creating busses for controllers.

2010-02-17omap: Remove DEBUG_FS dependency for mux name checkingRanjith Lohithakshan
The check for a valid mux name should be performed regardless of whether DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] last sysfs file: Modules linked in: CPU: 0 Not tainted (2.6.33-rc8 #10) PC is at strcmp+0x18/0x40 LR is at omap_mux_init_signal+0x68/0x14c ... This fixes the issue currently seen with boards not booting up if DEBUG_FS is not enabled in defconfig. Note that the earlier ifndef + ifdef now becomes simpler ifdef else: If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected, we only want the GPIO to mux register mapping.

2010-02-15ARM: vfp ptrace: no point flushing hw context for PTRACE_GETVFPREGSRussell King
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>
2010-02-15ARM: vfp: fix vfp_sync_state()Russell King
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.

2010-02-15ARM: 5905/1: ARM: Global ASID allocation on SMPCatalin Marinas
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>

2010-02-15ARM: 5889/1: Add atomic64 routines for ARMv6k and above.Will Deacon
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.
