Subject: [SPARC32]: Fix bogus ramdisk image location check.
X-Git-Tag: v2.6.23-rc4~127^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f642b263800e6e57c377d630be6d2a999683b579;p=linux-2.6

[SPARC32]: Fix bogus ramdisk image location check.

This mirrors sparc64 commit 715a0ecc29c850d2b2f76e1803d3f22cd5a0ac0d

sparc_ramdisk_image should always be decremented by KERNBASE.
