MIPS ptrace build fixes
Since Pedro's ptrace cleanups, the MIPS buildbot compilation fails.
Code in MIPS native uses ptrace with 3 arguments, where ptrace requires
4. When looking at the definition of ptrace in
/usr/include/sys/ptrace.h, it shows that it takes a variable number of
arguments. The wrapper macro in nat/gdb_ptrace.h takes a fixed number
of arguments (4). That would explain why it used to work and stopped.
I am pushing this as obvious, tell me if there is any problem.
I built-tested this with a MIPS toolchain (ct-ng), but I don't have any
setup to test it. At least it should put back the buildbot builder in a
better shape.
gdb/ChangeLog:
* mips-linux-nat.c (write_watchpoint_regs): Add NULL as ptrace's 4th
parameter.
(mips_linux_new_thread): Likewise.
* nat/mips-linux-watch.c (mips_linux_read_watch_registers): Likewise.
gdb/gdbserver/ChangeLog:
* linux-mips-low.c (mips_linux_prepare_to_resume): Add NULL as
ptrace's 4th parameter.
