Subject: [PATCH 0/5] [v3] fix illegal use of __pa() in KVM code
Date: Tue, 22 Jan 2013 13:24:28 -0800 [thread overview]
Message-ID: <20130122212428.8DF70119@kernel.stglabs.ibm.com> (raw)
This series fixes a hard-to-debug early boot hang on 32-bit
NUMA systems. It adds coverage to the debugging code,
adds some helpers, and eventually fixes the original bug I
was hitting.
[v3]
* Remove unnecessary initializations in slow_virt_to_phys(),
and convert 'level' to use the new enum pg_level.
* Add some text to slow_virt_to_phys() to make it clear
that we are not using it in any remotely fast paths.
[v2]
* Moved DEBUG_VIRTUAL patch earlier in the series (it has no
dependencies on anything else and stands on its own.
* Created page_level_*() helpers to replace a nasty switch()
at hpa's suggestion
