    Subject[patch 23/56] ACPICA: Fix table entry truncation calculation
    2.6.27-stable review patch.  If anyone has any objections, please let us know.
    ------------------

    From: Myron Stowe <myron.stowe@hp.com>

    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.
