Subject: x86, apic: Use PAGE_SIZE instead of numbers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=46dc281b1bb02527195fe2ad50a3af6d7f7f7325;p=mv-sheeva.git

x86, apic: Use PAGE_SIZE instead of numbers

The whole page is reserved for IO-APIC fixmap
due to non-cacheable requirement. So lets note
this explicitly instead of playing with numbers.
