Suresh Siddha wants to fix a possible FPU leakage in error conditions,
but the fact that save/restore_i387() are inlines in a header file makes
that harder to do than necessary. So start off with an obvious cleanup.
This just moves the x86-64 version of save/restore_i387() out of the
header file, and moves it to the only file that it is actually used in:
arch/x86/kernel/signal_64.c. So exposing it in a header file was wrong
to begin with.
[ Side note: I'd like to fix up some of the games we play with the
32-bit version of these functions too, but that's a separate
matter. The 32-bit versions are shared - under different names
at that! - by both the native x86-32 code and the x86-64 32-bit
compatibility code ]

IDE probing code used to skip devices attached to EATA SCSI HBA
in ATA emulating mode but because of warm-plug support port I/O
resources are no longer freed if no devices are detected on a port
and the decision about the driver to use is left up to the user.
Remove no longer valid EATA SCSI HBA quirk from do_identify().

cdrom_read_capacity() will blindly return the capacity from the device
without sanity-checking it. This later causes code in fs/buffer.c to
oops.
Fix this by checking that the device is telling us sensible things.

This controller supports UltraDMA up to mode 5 but it should be clocked with
at least twice the data strobe frequency, so enable mode 5 for 100+ MHz IDECLK.
While at it, start passing the correct device to clk_get() -- it worked anyway
but WTF? :-/
