From c6ac4c18fbc92a26df71ece609b082bc3099676b Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 20 May 2009 11:26:09 -0700 Subject: [PATCH] x86, boot: correct the calculation of ZO_INIT_SIZE Correct the calculation of ZO_INIT_SIZE (the amount of memory we need during decompression). One symbol (ZO_startup_32) was missing from zoffset.h, and another (ZO_z_extract_offset) was misspelled. [ Impact: build fix ] Signed-off-by: H.
