Subject: [PATCH] x86: parocessor.h - use PAGE_SIZE instead of numeric value v2
Date: Thu, 13 Mar 2008 19:44:56 +0300 [thread overview]
Message-ID: <20080313164456.GA7560@cvg> (raw)
This patch replaces numeric constant with an appropriate macro
Also 0x800000000000UL is changed to bit shifting which is complement
to the code comment (thanks hpa for notice)
