Please find attached an updated patch which uses arm_read_auxv, and
updates the warning messgaes.  I've tested the change on a Cortex-A9
board.

If this patch is okay can someone please commit it as I do not have
commit rights to the GDB repository.

Proposed ChangeLog:

2010-03-19  Matthew Gretton-Dann  <matthew.gretton-dann@arm.com>

        * arm-tdep.h (gdb_regnum): Add ARM_FPSCR_REGNUM
        * arm-linux-nat.c (arm_linux_vfp_register_count): Add new
        variable.
        (fetch_vfp_registers): New function to fetch VFP registers.
        (store_vfp_registers): New function to store VFP registers.
        (arm_linux_fetch_inferior_registers): Add support for VFP
        registers.
        (arm_linux_store_inferior_registers): Likewise.
        (arm_linux_read_description): Likewise.
        (_initialize_arm_linux_nat): Delay initialising iWMMX tdesc
        until we need it.

Thanks,

Matt
