Subject: [IA64] Add PAL_VM_SUMMARY/PAL_MEM_ATTRIB to bootloader for SKI
X-Git-Tag: v2.6.14-rc1~111^2~1^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dc90e95f310f4f821c905b2aec8e9449bb3270fa;p=linux-2.6

[IA64] Add PAL_VM_SUMMARY/PAL_MEM_ATTRIB to bootloader for SKI

This patch implements PAL_VM_SUMMARY (and PAL_MEM_ATTRIB for good
measure) and pretends that the simulated machine is a McKinley.

Some extra comments and clean-up by Tony Luck.
