Subject: s390: Put allocated ELF notes in read-only data segment
X-Git-Tag: v2.6.23-rc1~390
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=86ead9caf9a9f265f6065c46080d046230e25d78;p=linux-2.6-omap-h63xx.git

s390: Put allocated ELF notes in read-only data segment

This changes the s390 linker script to use the asm-generic NOTES macro so that
ELF note sections with SHF_ALLOC set are linked into the kernel image along
with other read-only data.  The PT_NOTE also points to their location.

This paves the way for putting useful build-time information into ELF notes
that can be found easily later in a kernel memory dump.
