Subject: [SPARC64]: Initialize LMB tables.
X-Git-Tag: v2.6.26-rc1~1089^2~20
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b2a7e23a9808e349bc5fb32327bacc5e81be79c;p=linux-2.6

[SPARC64]: Initialize LMB tables.

Call lmb_add() on available regions, and call lmb_reserve()
on the main kernel image and the ramdisk (if any).
