This returns the FADT support to the original behavior, which is
to use default register widths. However, now check each register
definition and report a warning if it differs from the default.
This is a first step to moving away from the default widths,
rather than outright believing the widths in all FADTs for all
machines, considered rather dangerous until more data is obtained.

1) Update the register lengths for the PM1 event blocks. The
length must be divided by two in order to use these to access
the status registers.
2) Add run-time option to use default register lengths to override a
faulty FADT.
3) Add warning message if any of the X64 address structures contain a length
that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.

acpi.h now includes only the "public" acpica headers. All other
acpica headers are "private" and should not be included by acpica
users. One new file, accommon.h is used to include the commonly
used private headers for acpica code generation. Future plans
are to move all private headers to a new subdirectory.

The (1.0 inherited) separate length fields in the FADT are byte granular.
Further, PM1a/b may have distinct lengths (if using the v2 fields was
okay) and may live in distinct address spaces. acpi_tb_convert_fadt()
should account for all of these conditions.
Apart from these changes I'm puzzled by the fact that, not just for
acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an
explicit size passed rather than using the size found in the passed GAS.
What happens on a platform that defines PM1{a,b} wider than 16 bits? Of
course, acpi_hw_low_level_{read,write}() at present are entirely
un-prepared to deal with sizes other than 8, 16, or 32, not to speak of a
non-zero bit_offset or access_width...

This reverts commit 01a5bba576b9364b33f61f0cd9fa70c2cf5535e2.
There seem to be some FADTs around with bogus information
in the v2 fields. Revert this patch for now until
this can be properly resolved.

No longer needed; replaced mostly with u32, but also acpi_size
where a type that changes 32/64 bit on 32/64-bit platforms is
required.
v2: Fix a cast of a 32-bit int to a pointer in ACPI to avoid a compiler warning.

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.)

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.
