x86/acpi: Correct out-of-date comment of __acpi_map_table()

}

/*

 * Temporarily use the virtual area starting from FIX_IO_APIC_BASE_END,

 * to map the target physical address. The problem is that set_fixmap()

 * provides a single page, and it is possible that the page is not

 * sufficient.

 * By using this area, we can map up to MAX_IO_APICS pages temporarily,

 * i.e. until the next __va_range() call.

 *

 * Important Safety Note:  The fixed I/O APIC page numbers are *subtracted*

 * from the fixed base.  That's why we start at FIX_IO_APIC_BASE_END and

 * count idx down while incrementing the phys address.

 * This is just a simple wrapper around early_ioremap(),

 * with sanity checks for phys == 0 and size == 0.
