55f8f3cc4f ACPICA: Clear reserved fields for incoming ACPI 1.0 FADTs
Fixed a problem with the internal FADT conversion where ACPI 1.0
FADTs that contained invalid non-zero values in reserved fields
could cause later failures because these fields have meaning in
later revisions of the FADT. For incoming ACPI 1.0 FADTs, these
fields are now always zeroed. (Preferred_PM_Profile, PSTATE_CNT,
CST_CNT, IAPC_BOOT_FLAGS.)

79fff27002 ACPICA: clear fields reserved before FADT r3
Linux-2.6.21 stopped booting on a P4/HT because Linux
wrote the FADT.CST_CNT value to the SMI_CMD.
Apparently this stumbled over some SMM instability,
such as confusing SMM when invoking it from cpu1.

Linux did this because even though the r2 FADT reserves
the CST_CNT field, this BIOS set that field and Linux
used it.

Turns out that up through 2.6.20 we explicitly cleared
cst_control for r2 FADTs.  So here we go back to doing that,
plus also clear some additional fields that are reserved
until FADT r3.
