[PATCH 0/2] amd64: add fs_base and gs_base


The next two patches add Linux system registers fs_base and gs_base
in GDB and gdbserver.

First commit align the gdbserver with GDB code  in terms of
HAVE_STRUCT_USER_REGS_STRUCT_(GS|FS)_BASE.

Second patch introduces the registers into GDB and gdbserver.


Walfred Tedeschi (2):
  gdbserver-amd64: add HAVE_STRUCT_USER_REGS_STRUCT_(GS|FS)_BASE for
    gdbserver.
  amd64-linux: expose system register FS_BASE and GS_BASE for Linux.
