Subject: Blackfin arch: redo our linker script a bit
X-Git-Tag: v2.6.22-rc5~27^2~9
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=de6a9520d4c799ce2079c59457b06251367e67b6;p=linux-2.6-omap-h63xx.git

Blackfin arch: redo our linker script a bit

 - we can start taking advantages of defines in asm-generic/vmlinux.lds.h
 - move our L1 relocated sections into init so it gets freed after relocation
