2006-03-28	[ARM] 3377/2: add support for intel xsc3 core	Lennert Buytenhek	1	-0/+19
	Patch from Lennert Buytenhek This patch adds support for the new XScale v3 core. This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.

2006-03-15	[ARM] 3364/1: [cleanup] warning fix - definitions for enable_hlt and disable_hlt	Ben Dooks	1	-0/+3
	Patch from Ben Dooks The enable_hlt and disable_hlt should be declared in include/asm/setup.h. This fixes sparse errors from arch/arm/kernel/process.c Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-12	[PATCH] arm: task_thread_info()	Al Viro	1	-1/+1

2006-01-12	[PATCH] sched: add cacheflush() asm	Ingo Molnar	1	-0/+10
	Add per-arch sched_cacheflush() which is a write-back cacheflush used by the migration-cost calibration code at bootup time.

2005-11-16	[ARM] No need to include asm/proc-fns.h into asm/system.h	Russell King	1	-2/+2
	In the old days when arm26/arm32 was combined into the same architecture, proc-fns.h provided the xchg implementation for arm26 CPUs. Since we no longer combine these two, this include is no longer required. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-07-26	[PATCH] ARM SMP: Add ARMv6 memory barriers	Russell King	1	-0/+5
	Convert explicit gcc asm-based memory barriers into smp_mb() calls. These change between barrier() and the ARMv6 data memory barrier instruction depending on whether ARMv6 SMP is enabled. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-07-26	[PATCH] ARM SMP: Use exclusive load/store for __xchg	Russell King	1	-29/+58
	Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-30	[PATCH] ARM: Don't try to send a signal to pid0	Russell King	1	-1/+3
	If we receive an unrecognised abort during boot, don't try to send a signal to pid0, but instead report the current state. This leads to less confusing debug reports. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-28	[PATCH] ARM SMP: __xchg support	Russell King	1	-3/+9
	This enables the existing __xchg implementation to be used on SMP. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-25	[PATCH] sched: cleanup context switch locking	Nick Piggin	1	-26/+4
	Instead of requiring architecture code to interact with the scheduler's locking implementation, provide a couple of defines that can be used by the architecture to request runqueue unlocked context switches, and ask for interrupts to be enabled over the context switch. Also replaces the "switch_lock" used by these architectures with an oncpu flag (note, not a potentially slow bitflag). This eliminates one bus locked memory operation when context switching, and simplifies the task_running function.

2005-06-21	[PATCH] arm: irqs_disabled() type fix	Andrew Morton	1	-1/+1
	kernel/sched.c: In function `__might_sleep': kernel/sched.c:5461: warning: int format, long unsigned int arg (arg 3) We expect irqs_disabled() to return an int (poor man's bool).

2005-06-19	[PATCH] ARM SMP: Fix PXA/SA11x0 suspend resume crash	Russell King	1	-0/+1
	We need to re-initialise the stack pointers for undefined, IRQ and abort mode handlers whenever we resume. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-04-17	[PATCH] ARM: showregs	Russell King	1	-0/+3
	Fix show_regs() to provide a backtrace. Provide a new __show_regs() function which implements the common subset of show_regs() and die(). Add prototypes to asm-arm/system.h Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+390
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
