* sparc64: Fix memory leak in pci_register_iommu_region().David S. Miller2010-05-12
| | | | | | | | | | | | | | | | [ Upstream commit e182c77cc291456eed127b1472952ddb59a81a9d ] Found by kmemleak. If request_resource() fails, we leak the struct resource we allocated to represent the IOMMU mapping area. This actually happens on sun4v machines because the IOMEM area is only reported sans the IOMMU region, unlike all previous systems. I'll need to fix that at some point, but for now fix the leak.

* sparc64: Use kstack_valid() in die_if_kernel().David S. Miller2010-05-12
| | | | | | | | | | | [ Upstream commit cb256aa60409efd803806cfb0528a4b3f8397dba ] This gets rid of a local function (is_kernel_stack()) which tries to do the same thing, yet poorly in that it doesn't handle IRQ stacks properly.

* sparc64: Fix hardirq tracing in trap return path.David S. Miller2010-05-12
| | | | | | | | | | | | | [ Upstream commit 28a1f533ae8606020238b840b82ae70a3f87609e ] We can overflow the hardirq stack if we set the %pil here so early, just let the normal control flow do it. This is fine as we are allowed to do the actual IRQ enable at any point after we call trace_hardirqs_on. Signed-off-by: David S.

* sparc64: Properly truncate pt_regs framepointer in perf callback.David S. Miller2010-04-01
| | | | | | | | | | | | | | | | | | [ Upstream commit 9e8307ecaf9f8c8b5b3b22145021204c4e73114a ] For 32-bit processes, we save the full 64-bits of the regs in pt_regs. But unlike when the userspace actually does load and store instructions, the top 32-bits don't get automatically truncated by the cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM address masking enabled). So we have to do it by hand. Reported-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* perf: Provide generic perf_sample_data initializationPeter Zijlstra2010-04-01
| | | | | | | | | | | | | | | | | | | | | This makes it easier to extend perf_sample_data and fixes a bug on arm and sparc, which failed to set ->raw to NULL, which can cause crashes when combined with PERF_SAMPLE_RAW. It also optimizes PowerPC and tracepoint, because the struct initialization is forced to zero out the whole structure.

* sparc: convert to arch_gettimeoffset()John Stultz2010-01-15
| | | | | | | | | | | | | | | | | | | This patch converts sparc (specifically sparc32) to use GENERIC_TIME via the arch_getoffset() infrastructure, reducing the amount of arch specific code we need to maintain. The sparc architecture is one of the last 3 arches that need to be converted. This patch applies on top of Linus' current -git tree I've taken my best swing at converting this, but I'm not 100% confident I got it right. My cross-compiler is now out of date (gcc4.2) so I wasn't able to check if it compiled. Any assistance from arch maintainers or testers to get this merged would be great.

We should only allow I/O ranges for I/O addresses, and only allow CONFIG space ranges for CONFIG space address. However for MEM ranges, they come in 32-bit and 64-bit flavors. And a lack of an exact match is OK if the range is 32-bit and the address is 64-bit. We can assign a 64-bit address properly into a 32-bit parent range just fine. So allow it.
