2008-08-13sparc64: Handle stack trace attempts before irqstacks are setup.David S. Miller2-20/+21
Things like lockdep can try to do stack backtraces before the irqstack blocks have been setup. So don't try to match their ranges so early on. Also, remove unused variable in save_stack_trace(). Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-12sparc64: Implement IRQ stacks.David S. Miller8-30/+161
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-12sparc: remove include of linux/of_device.h from asm/of_device.hStephen Rothwell1-2/+1
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>
2008-08-12sparc64: Fix recursion in stack overflow detection handling.David S. Miller1-3/+14
The calls down into prom_printf() when we detect an overflowed stack can recurse again since the overflow stack will be "below" the current kernel stack limit. Prevent this by just returning straight if we are on the stack overflow safe stack already. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-09sparc64: Don't MAGIC_SYSRQ ifdef smp_fetch_global_regs and support code.David S. Miller2-6/+0
Based upon a report and initial patch by Friedrich Oslage. The intention is to provide this facility for __trigger_all_cpu_backtrace even if MAGIC_SYSRQ is not set. The only part that should have MAGIC_SYSRQ ifdef protection is the sparc_globalreg_op sysrq regitration and immediate code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-07sparc64: Fix end-of-stack checking in save_stack_trace().David S. Miller1-2/+4
Bug reported by Alexander Beregalov. Before we dereference the stack frame or try to peek at the pt_regs magic value, make sure the entire object is within the kernel stack bounds. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-04sparc64: Remove all cpumask_t local variables in xcall dispatch.David S. Miller1-24/+9
All of the xcall delivery implementation is cpumask agnostic, so we can pass around pointers to const cpumask_t objects everywhere. The sad remaining case is the argument to arch_send_call_function_ipi(). Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Kill error_mask from hypervisor_xcall_deliver().David S. Miller1-13/+7
It can eat up a lot of stack space when NR_CPUS is large. We retain some of it's functionality by reporting at least one of the cpu's which are seen in error state. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Build cpu list and mondo block at top-level xcall_deliver().David S. Miller1-44/+69
Then modify all of the xcall dispatch implementations get passed and use this information. Now all of the xcall dispatch implementations do not need to be mindful of details such as "is current cpu in the list?" and "is cpu online?" Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-04sparc64: Make all xcall_deliver's go through common helper function.David S. Miller1-4/+9
This just facilitates the next changeset where we'll be building the cpu list and mondo block in this helper function. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Always allocate the send mondo blocks, even on non-sun4v.David S. Miller1-3/+16
The idea is that we'll use this cpu list array and mondo block even for non-hypervisor platforms. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Make smp_cross_call_masked() take a cpumask_t pointer.David S. Miller1-7/+11
Ideally this could be simplified further such that we could pass the pointer down directly into the xcall_deliver() implementation. But if we do that we need to do the "cpu_online(cpu)" and "cpu != self" checks down in those functions. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Directly call xcall_deliver() in smp_start_sync_tick_client.David S. Miller1-4/+2
We know the cpu is online and not the current cpu here. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-04sparc64: Call xcall_deliver() directly in some cases.David S. Miller1-23/+10
For these cases the callers make sure: 1) The cpus indicated are online. 2) The current cpu is not in the list of indicated cpus. Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.

2008-08-04sparc64: Use xcall_deliver() consistently.David S. Miller1-23/+17

2008-08-04sparc64: Need to disable preemption around smp_tsb_sync().David S. Miller1-1/+4
Based upon a bug report by Mariusz Kozlowski It uses smp_call_function_masked() now, which has a preemption-disabled requirement. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-04add addrespace definition for sh2a.Takashi Yoshii1-0/+10
Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h), but, I'd like to add sh2a specific file here, because 1. the values defined there are not suitable for sh2a. 2. I don't think there is "common" definition for these values. Values are chosen by consideration of followings... P1 is 0. perhaps no question. P2 is from hardware manual, which says no-cache area starts at 20000000. It means that P? space size=20000000. P3 is P2+size since asm/ptrace.h uses P3 as a end of P2. P4 is P3+size since asm/fixup.h uses P4 as a end of P3. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-04sh: Kill off ARCH_SUPPORTS_AOUT and remnants of a.out support.Paul Mundt2-23/+0
SH never really supported a.out, so this was all just copied over blindly from x86 way back when. As we don't reference linux/a.out.h anywhere in the tree, these can now safely be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-04sh: define GENERIC_HARDIRQS_NO__DO_IRQ.Paul Mundt1-0/+3
