    parisc: add me to Maintainers
    
    It has been suggested that given my proficiency with less popular
    architectures, I should be officially listed as willing to see to the
    care and feeding of this one.

    parisc: arch/parisc: correct use of SHF_ALLOC
    
    SHF_ALLOC is suitable for testing against the sh_flags field, not the
    sh_type field.

    parisc: only allow access to USER_PSW_BITS in setregs
    
    We don't want to let users fribble bits they don't need to in their
    PSW... only let them set USER_PSW_BITS from setregs functions.

    parisc: unify compat PTRACE_{GET|SET}REGS paths
    
    Just call arch_ptrace for all of them and add some helpers to
    check TIF_32BIT.

    parisc: ptrace {GET,SET}REGS and compat
    
    Add PTRACE_{GET,SET}REGS and wire them up with proper compat handlers.
    user_regset_struct in <asm-parisc/ptrace.h> is the user-visible regset
    format, and the coredump format.

    parisc: first pass of new-style ptrace for parisc
    
    This is going to be super nasty to gdb if we ever try to wire up
    PTRACE_(GET|SET){,FP}REGS since the format is different between
    coredump and pt_regs.

    parisc: stop using task->ptrace for {single,block}step flags
    
    task->ptrace flags belong to generic code, so instead thief some
    TIF_ bits to use. Somewhat risky conversion of code to test TASK_FLAGS
    instead of TASK_PTRACE in assembly, but it looks alright in the end.

    parisc: split syscall_trace into two halves
    
    Instead of fiddling with gr[20], restructure code to return whether
    or not to -ENOSYS. (Also do a bit of fiddling to let them take
    pt_regs directly instead of re-computing it.)

    parisc: add missing TI_TASK macro in syscall.S
    
    LDREG 0(%r1),%r1 really wants to be accessing thread_info.task,
    instead of hardcoding the 0.

    parisc: tracehook_signal_handler
    
    This makes parisc call the standard tracehook_signal_handler hook
    in <linux/tracehook.h> after setting up a signal handler.

    parisc: tracehook_report_syscall
    
    This makes parisc use the standard tracehook_report_syscall_entry
    and tracehook_report_syscall_exit hooks in <linux/tracehook.h>.
    
    To do this, we need to access current->thread.regs, and to know
    whether we're entering or exiting the syscall, so add this to
    syscall_trace.
