ACPICA: Fix table entry truncation calculation
commit 386e4a8358239f90275e1f93d5ad11cdc93c6453 upstream.
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).
This modification may be used under either the GPL or the BSD-style
license used for Intel ACPI CA code.
