When the connection between host and storage server is lost, the
dasd device driver usually blocks all I/O on affected devices and
waits for them to reappear. In some setups however it would be
better if the I/O is returned as error so that device can be
recovered by some other means, eg. in a raid or multipath setup.

The clear_fixmap() routine issues map_page() with flags set to 0.

The patch replaces internal registers dump implementation with
ppc_save_regs(). From now on PPC64 and PPC32 are using the same
code for crash_setup_regs().

NOTE: The old regs dump implementation was capturing SP (r1) directly
as is, so you could see crash_kexec() function on top of the back-trace.
But ppc_save_regs() goes up one stack frame, so you'll not see it
anymore, at the top-level you'll see who actually triggered the crash
dump instead.
