2008-08-12sparc64: Implement IRQ stacks.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-12sparc: remove include of linux/of_device.h from asm/of_device.hStephen Rothwell
Now that all the direct includes of asm/of_device.h are gone, this is safe to do. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-07sparc: don't use asm/of_device.hStephen Rothwell
Use linux/of_device.h instead. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-06of/sparc: remove include of linux/of_platform.h from asm/of_platform.hStephen Rothwell
Now that we have removed all inclusions of asm/of_platform.h, this compatability include can be removed. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-31sparc: Add __KERNEL__ ifdef protection to pt_regs helpers.David S. Miller
Some of them use 'bool' and whatnot and therefore are not kosher for userspace, so don't export them there. Reported by Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-30sparc64: Hook up trigger_all_cpu_backtrace().David S. Miller
We already have code that does this, but it is only currently attached to sysrq-'y'. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-30sparc64: Make global reg dumping even more useful.David S. Miller
Record one more level of stack frame program counter. Particularly when lockdep and all sorts of spinlock debugging is enabled, figuring out the caller of spin_lock() is difficult when the cpu is stuck on the lock. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-30sparc64: FUTEX_OP_ANDN fixMikael Pettersson
Correct sparc64's implementation of FUTEX_OP_ANDN to do a bitwise negate of the oparg parameter before applying the AND operation. All other archs that support FUTEX_OP_ANDN either negate oparg explicitly (frv, ia64, mips, sh, x86), or do so indirectly by using an and-not instruction (powerpc). Since sparc64 has and-not, I chose to use that solution. I've not found any use of FUTEX_OP_ANDN in glibc so the impact of this bug is probably minor. But other user-space components may try to use it so it should still get fixed. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-29sparc: merge of_platform_{32,64}.hStephen Rothwell

2008-07-29sparc64: Kill isa_bus_type.David S. Miller
I forgot to delete this when I removed the ISA bus layer from the sparc ports. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-27sparc: Add task_pt_regs().David S. Miller

2008-07-27sparc: Create and use TIF_NOTIFY_RESUME.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-27sparc: Add user_stack_pointer().David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-27sparc64: tracehook: TIF_NOTIFY_RESUMERoland McGrath
This adds TIF_NOTIFY_RESUME support for sparc64. When set, we call tracehook_notify_resume() on the way to user mode. Signed-off-by: Roland McGrath <roland@redhat.com>
2008-07-27sparc: Add asm/syscall.hDavid S. Miller
Based upon a patch by Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-27sparc: enable headers_export againSam Ravnborg
Update include/asm/Kbuild so we export all relvant headers for sparc. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-07-27sparc, sparc64: use arch/sparc/includeSam Ravnborg
The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
