Subject: HWPOISON: convert pr_debug()s to pr_info()s
X-Git-Tag: next-20110929~2^2~133
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c1163fc19cee72e8724125fc7cdc66d8728d79b0;p=karo-tx-linux.git

HWPOISON: convert pr_debug()s to pr_info()s

Commit fb46e73520940b ("HWPOISON: Convert pr_debugs to pr_info) authored
by Andi Kleen converted a number of pr_debug()s to pr_info()s.

About the same time additional code with pr_debug()s was added by two
other commits 8c6c2ecb4466 ("HWPOSION, hugetlb: recover from free hugepage
error when !MF_COUNT_INCREASED") and d950b95882f3d ("HWPOISON, hugetlb:
soft offlining for hugepage").  And these pr_debug()s failed to get
converted to pr_info()s.

This patch converts them as well.  And does some minor related whitespace
cleanup.
