This interface allows the host to override a table via a
physical address, instead of the logical address required by
acpi_os_table_override. This simplifies the host implementation.
Initial implementation by Thomas Renninger. ACPICA implementation
creates a single function for table overrides that attempts both
a logical and a physical override.

Add warning message to ask users to use this option if corrupt DSDT detected.

During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array.  This array is currently statically defined (see
./drivers/acpi/tables.c).  When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output.  As currently implemented, this message will always
erroneously calculate N as 0.

This patch fixes the calculation that determines how many table entries
will be missing (truncated).

On some boxes there exist both RSDT and XSDT table. But unfortunately
sometimes there exists the following error when XSDT table is used:
   a. 32/64X address mismatch
   b. The 32/64X FACS address mismatch

   In such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.

ACPI 1.0 used an RSDT with 32-bit physical addresses.
ACPI 2.0 adds an XSDT with 32-bit physical addresses.
An ACPI 2.0 aware OS is supposed to use the XSDT
(when present) instead of the RSDT.

However, several systems have failed because the XSDT
contains NULL entries -- while it is missing pointers
to needed tables, such as SSDTs.

When we find an XSDT with NULL entries, discard it
and use the ACPI 1.0 RSDT instead.
