This is a build fix required after "x86-64: seccomp: fix 32/64 syscall hole" (commit 5b101740). MIPS doesn't have the issue that was fixed for x86-64 by that patch. This also doesn't solve the N32 issue which is that N32 seccomp processes will be treated as non-compat processes thus only have access to N64 syscalls.

Use fixmaps instead of vmap/vunmap in text_poke() for avoiding page allocation and delayed unmapping.

ds_write_config() can write the BTS as well as the PEBS part of the DS config. ds_request_pebs() passes the wrong qualifier, which results in the wrong configuration to be written.

In case a ptraced task is reaped (while the tracer is still attached), ds_exit_thread() is called before ptrace_exit(). The latter will release the bts_tracer and remove the thread's ds_ctx. The former will WARN() if the context is not NULL. Oleg Nesterov submitted patches that move ptrace_exit() before exit_thread() and thus reverse the order of the above calls. Remove the bad warning. I will add it again when Oleg's changes are in.

This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory Controller with Compact Flash True IDE Mode logic. Driver have to switch 8/16 bit bus width when accessing Task Tile or Data Register. Moreover some extra things need to be done when setting PIO mode. Only PIO mode is used, hardware have no DMA support. If interrupt line is connected through GPIO extra quirk is needed to cope with fake interrupts.
