[PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 drive

This patch works around a problem with spurious interrupts seen at boot time when
a MAXTOR 6H500F0 drive is present.  An ATA interrupt condition is mysteriously
present at start of day.  If we took too long in issuing the first command,
the kernel would basically get tired of the spurious interrupts and turn the interrupt
off.  Issuing the first command essentially causes the interrupt condition to
get acknowledged.

I haven't seen this happen with any other drives.

What I basically do is ack ATA status by reading it regardless of whether we're
expecting to have to handle an interrupt.  This clears the start-of-day anomalous
interrupt condition, and keeps the kernel from disabling that interrupt due to
too many spurious interrupts.

Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled
in the ISR.  This was not the cause of the spurious interrupts, but it's the right
thing to do anyway.

Previously, the host_build_iv flag couldn't be used at all for WEP, and
not alone (with both host_decrypt and host_encrypt disabled) because the

In 2.6.15, as part of the great powerpc merge, we moved this definition to

arch/ppc/boot/common/util.S:

        .section ".relocate_code","xa"
[...]
_GLOBAL(flush_instruction_cache)
[...]
_GLOBAL(flush_data_cache)
[...]

The addition of the .text section definition in the definition of
_GLOBAL overrides the .relocate_code section definition.  As a result,
these two functions don't end up in .relocate_code, so they don't get
relocated correctly, and the boot fails.

There's another suspicious-looking usage at kernel/swsusp.S:37 that
someone should look into.  I did not exhaustively search the source
tree, though.

The following is the minimal patch that fixes the immediate problem.
I could easily be convinced that the _GLOBAL definition should be
modified to remove the ".text;" line either instead of, or in addition
to, this fix.
