Subject: x86-64: fix initrd freeing
X-Git-Tag: v2.6.16-rc1~87
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f74e6670c4a788c9a0c52ab2036d8ac6be12f1d8;p=linux-2.6

x86-64: fix initrd freeing

The comparison of the initrd start address against "&_end" is
unnecessary and incorrect.  Make it match the x86 code that just
compares the passed-in arguments.
