2005-11-02	[PATCH] powerpc: Merge futex.h	David Gibson	1	-0/+7
	This patch merges the ppc32 and ppc64 versions of futex.h, essentially by taking the ppc64 version as the powerpc version. The old ppc32 version did not implement the futex_atomic_op_inuser() callback (it always returned -ENOSYS), so FUTEX_WAKE_OP would not work on ppc32. In fact the ppc64 version of this function is almost suitable for ppc32 as well - the only change needed is to extend ppc_asm.h with a macro expanding to to the right pseudo-op to store a pointer (either ".long" or ".llong"). Built and booted on pSeries. Built for 32-bit powermac. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-28	powerpc: Merge xmon	Paul Mackerras	1	-0/+8
	The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

2005-10-27	powerpc: Introduce toreal/fromreal assembly macros	Paul Mackerras	1	-14/+15
	On 32-bit platforms, these convert from kernel virtual addresses to real (physical addresses), like tophys/tovirt but they use the same register for the source and destination. On 64-bit platforms, they do nothing because the hardware ignores the top two bits of the address in real mode. These new macros are used in fpu.S now.

2005-10-26	[PATCH] powerpc: Remove trailing \n" in HMT macros	Michael Ellerman	1	-7/+7
	GCC 3.3.3 barfs on the trailing \n" in the HMT macros. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-17	powerpc: fix 32bit LOADADDR macro	Stephen Rothwell	1	-1/+1

2005-10-13	powerpc: create 32 bit LOADADDR macro	Stephen Rothwell	1	-0/+4
	and use it in misc_32.S Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-10	powerpc: Get 64-bit configs to compile with ARCH=powerpc	Paul Mackerras	1	-26/+66
	This is a bunch of mostly small fixes that are needed to get ARCH=powerpc to compile for 64-bit. This adds setup_64.c from arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06	powerpc: Define 32/64 bit asm macros and use them in fpu.S	Paul Mackerras	1	-5/+23
	These macros help in writing assembly code that works for both ppc32 and ppc64. With this we now have a common fpu.S. This takes out load_up_fpu from head_64.S. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-25	[PATCH] powerpc: merge atomic.h, memory.h	Becky Bruce	1	-0/+3
	powerpc: Merge atomic.h and memory.h into powerpc Merged atomic.h into include/powerpc. Moved asm-style HMT_ defines from memory.h into ppc_asm.h, where there were already HMT_defines; moved c-style HMT_ defines to processor.h. Renamed memory.h to synch.h to better reflect its contents.

2005-09-19	[PATCH] powerpc: Merged ppc_asm.h	Kumar Gala	1	-0/+437
	Merged ppc_asm.h between ppc32 & ppc64. The majority of the file is common between the two architectures excluding how a single GPR is saved/restored and which GPRs are non-volatile. Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
