sparc,sparc64: unify kernel/

2008-12-04T17:17:21+00:00

o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

sparc64: Make %pil level 15 a pseudo-NMI.

2008-12-04T17:17:02+00:00

So that we can profile code even in a local_irq_disable() section, only write 14 (instead of 15) into the %pil register to disable IRQs. This allows PIL level 15 to serve as a pseudo NMI. Signed-off-by: David S. Miller

sparc64: Stop using memory barriers for atomics and locks.

2008-12-04T17:16:47+00:00

The kernel always executes in the TSO memory model now, so none of this stuff is necessary any more. With helpful feedback from Nick Piggin. Signed-off-by: David S. Miller

sparc64: Fix SMP bootup with CONFIG_STACK_DEBUG or ftrace.

2008-09-16T18:44:00+00:00

Based upon a report by Meelis Roos. Any function call can try to access the current thread register via the _mcount hooks when the kernel is built with -pg (via ftrace or STACK_DEBUG). That can't be setup properly very early on during the bootup of other cpus for sun4u and some early sun4v systems. So add notrace markers to these specific functions, so that _mcount doesn't get invoked too early. Signed-off-by: David S. Miller

sparc64: Fix sparse warnings in pci.c

2008-09-12T06:57:40+00:00

1) Declare pci_poke_* in pci_impl.h 2) of_create_pci_dev() should be static 3) ->setup_msi_irq() wants an unsigned int pointer not a plain int one 4) void value expression return in arch_teardown_msi_irq() Signed-off-by: David S. Miller

sparc64: Fix sparse warnings in visemul.c

2008-09-12T06:46:40+00:00

1) edge8 tables should be static 2) add vis_emul() extern decl. to asm/visasm.h Signed-off-by: David S. Miller

sparc64: Allow chmc to be built as a module.

sparc64: Add generic interface for registering a dimm printing handler.

2008-08-25T05:08:34+00:00

The way to do this varies by platform type and the exact memory controller the cpu uses. For Spitfire cpus we currently just use prom_getunumber() and hope that works. For Cheetah cpus we have a memory controller driver that can compute this information. Signed-off-by: David S. Miller
