Drop all uses of deprecated genirq features. The irq_set_affinity() call got a third paramter 'force' which is unused. For now genirq does not use this paramter and it is ignored by sparc.

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.

This is useful for system management software so that it can kick off things like gettys and everything that's started from a tty, before we reuse it from/for something else or shut it down.

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: NDavid S. Miller <davem@davemloft.net>

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.

Since commit f0e98c38 ("[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.

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.
