Subject: Define N_PRIMARY_MAP to actually generate a 64-bit constant on 64-bit
X-Git-Tag: svn/VALGRIND_3_0_0~738
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e014d5790ab780d24387496ac16c95c5d8a573bb;p=thirdparty%2Fvalgrind.git

Define N_PRIMARY_MAP to actually generate a 64-bit constant on 64-bit
platforms, otherwise the address-masking operations to establish
alignment and primary-mappability are wrong on 64-bit platforms.

Also set the size of fast-mapped address space on 64-bit platforms to
16G.
