Fix a long-standing bug in the stack backtracer where we would print garbage to the console instead of kernel function names, if the kernel wasn't built with symbol support (e.g. mboot). Make sure to tag every line of userspace backtrace output if we actually have the mmap_sem, since that way if there's no tag, we know that it's because we couldn't trylock the semaphore. Stop doing a TLB flush and examining page tables during backtrace. Instead, just trust that __copy_from_user_inatomic() will properly fault and return a failure, which it should do in all cases. Fix a latent bug where the backtracer would directly examine a signal context in user space, rather than copying it safely to kernel memory first. This meant that a race with another thread could potentially have caused a kernel panic. Guard against unaligned sp when trying to restart backtrace at an interrupt or signal handler point in the kernel backtracer. Report kernel symbolic information for the call instruction rather than for the following instruction. We still report the actual numeric address corresponding to the instruction after the call, for the sake of consistency with the normal expectations for stack backtracers.

Commit bd119c69 "Disintegrate asm/system.h for Tile" created the asm/switch_to.h file, but did not add an include of it to all its users. Also, commit b4816afa "Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h" introduced the concept of asm/cmpxchg.h but the tile arch never got one. Fork the cmpxchg content out of the asm/atomic.h file to create one.

This does a sweeping change fixing up all the missing system_misc.h and system_info.h includes from the system.h split-up change. These were the ones I came across when building all defconfigs in arch/arm/configs, there might be more but they lack adequate build coverage to be easily caught. I'm expecting to get a lot of these piecemeal by each maintainer, so we might just as well do one sweeping change to get them all at once.

When processor is being hot-added to the system, acpi_map_lsapic invokes ACPI _MAT method to find APIC ID and flags, verifies that returned structure is indeed ACPI's local APIC structure, and that flags contain MADT_ENABLED bit. Then saves APIC ID, frees structure - and accesses structure when computing arguments for acpi_register_lapic call. Which sometime leads to acpi_register_lapic call being made with second argument zero, failing to bring processor online with error 'Unable to map lapic to logical cpu number'. As lapic->lapic_flags & ACPI_MADT_ENABLED was already confirmed to be non-zero few lines above, we can just pass unconditional ACPI_MADT_ENABLED to the acpi_register_lapic.

This adopts a trimmed down version of the MIPS port mangling interface limited to the I/O swabbing for platforms that can't use little endian accessors. For platforms with mixed I/O spaces involving PCI it will still be necessary to enable byte swapping at the host controller level. Attention needs to be paid to all of host controller endianness, CPU endianness, and whether I/O accesses are explicitly swapped or not via SWAP_IO_SPACE. Fortunately the platforms that need this are in the minority. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
