* sparc32: add irq + smp declarations to headersSam Ravnborg2011-03-16
| | | | | | | | | | | | | | | | | | | In preparation for cleaning up a number of files add declarations for irq and smp related data/functions to the relevant headers. This showed that the extern declaration of cputypval differed in the two files where it was used. As cputypval is defined like this: cputypval: .asciz "sun4c" the correct representation is a char array. Fix users to use the new declaration.

* sparc32: remove tick14.cSam Ravnborg2011-03-16

* SPARC/LEON: power down instruction different of different LEONsDaniel Hellstrom2011-03-16
| | | | | | | | | | | | | | | The way a LEON is powered down is implemented differently depending on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB and CHIP. This is for example needed by the GR-LEON4-ITX board and the UT699. Previously the power down support for LEON was limited to SMP, now both SMP and UP systems use the instruction.

* sparc64: rename virt_irq => irq - IISam Ravnborg2011-03-16
| | | | | | | | | | | The generic irq support uses the term 'irq' for the allocated irq number. Fix it so sparc64 use the same term for an irq as the generic irq support does.

| | | | | | | | | | | | | | Drop all uses of deprecated genirq features. The irq_set_affinity() call got a third paramter 'force' which is unused.

* | | futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse2011-03-11
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

| * sparc64: Fix NMI startup bug which also breaks perf.David S. Miller2011-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Doing NMI startup as an early initcall doesn't work because we need to have SMP started up by then. So we'd only NMI startup one cpu, which causes perf PMU grab to BUG because the nmi_active count isn't what it's supposed to be. This also points out that we don't have proper CPU up/down notifiers for the NMI code which will need to be fixed at some point. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc: fix size argument to find_next_zero_bit()Akinobu Mita2011-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iommu_alloc_ctx() finds a zero bit in iommu->ctx_bitmap. It starts searching from iommu->ctx_lowest_free to the end of the bitmap. But the size argument to find_next_zero_bit() in iommu_alloc_ctx() is wrong. It should be the bitmap size, not the maximum size to search from the offset argument. Fortunately iommu->ctx_lowest_free is almost unused and it will not be more than 1. So the bug wasted only 1-bit at the end of iommu->ctx_bitmap.

| * sparc32: unaligned memory access (MNA) trap handler bugDaniel Hellstrom2011-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit f0e98c387e61de00646be31fab4c2fa0224e1efb ("[SPARC]: Fix link errors with gcc-4.3") the MNA trap handler does not emulate stores to unaligned addresses correctly. MNA operation from both kernel and user space are affected. A typical effect of this bug is nr_frags in skbs are overwritten during buffer copying/checksum-calculation, or maximally 6 bytes of data in the network buffer will be overwitten with garbage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pte alloc routines must wait for split_huge_page if the pmd is not present and not null (i.e. pmd_trans_splitting). The additional branches are optimized away at compile time by pmd_trans_splitting if the config option is off. However we must pass the vma down in order to know the anon_vma lock to wait for.

* | mm: unify module_alloc code for vmallocDavid Rientjes2011-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for module_init(). Much of the code is duplicated and can be generalized in a globally accessible function, __vmalloc_node_range(). __vmalloc_node() now calls into __vmalloc_node_range() with a range of [VMALLOC_START, VMALLOC_END) for functionally equivalent behavior. Each architecture may then use __vmalloc_node_range() directly to remove the duplication of code.
