Subject: powerpc/BSR: add 4096 byte BSR size
X-Git-Tag: v2.6.31-rc2~81^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e4031d52c57b17c76bbdb15fcf1a32a9f87d9756;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

powerpc/BSR: add 4096 byte BSR size

Add a 4096 byte BSR size which will be used on new machines.  Also, remove
the warning when we run into an unknown size, as this can spam the kernel
log excessively.
