yeah still hitting this.
looking at the issue if I change:
@@ 260
if ((class == 0xffffffff))
continue;
to
if ((class == 0xffffffff || 0xffffffffffffffff))
continue;
I'm able to boot, but don't have enough knowledge to know
what is really happening(or how to execute this).
will continue looking at this
(hopefully I get somewhere on this);

Hmm, I'm discovering the /proc/lock_stat file this evening, did not
know it exist :)
Still, a tree representation can bring another dimension.

Needs more brackets around arguments, otherwise someone calling it with
a complex expression will get very upset.
Or just replace with a static inline function?

The core_text_size test should be enough here.

Much of this code might be neater if you created a helper:
void set_page_attributes(void *start, void *end,
void (*set)(unsigned long start, unsigned long num_pages))
{
unsigned long begin_pfn = PFN_DOWN((unsigned long)start);
unsigned long end_pfn = PFN_DOWN((unsigned long)end);
if (end_pfn > begin_pfn)
set(begin_pfn << PAGE_SHIFT, end_pfn - begin_pfn);
}
But these are minor: patch looks good!
Thanks,
Rusty.

Sorry that I was slow to respond. (I was out of town.)
Thanks for catching __page_cache_release() locking the zone.
I think staying simple for now sounds good. The below locks
and unlocks the zone for each page. Look good?

readahead: retain inactive lru pages to be accessed soon
From: Chris Frost <frost@cs.ucla.edu>
Ensure that cached pages in the inactive list are not prematurely evicted;
move such pages to lru head when they are covered by
- in-kernel heuristic readahead
- an posix_fadvise(POSIX_FADV_WILLNEED) hint from an application
Before this patch, pages already in core may be evicted before the
pages covered by the same prefetch scan but that were not yet in core.
Many small read requests may be forced on the disk because of this
behavior.
In particular, posix_fadvise(... POSIX_FADV_WILLNEED) on an in-core page
has no effect on the page's location in the LRU list, even if it is the
next victim on the inactive list.
This change helps address the performance problems we encountered
while modifying SQLite and the GIMP to use large file prefetching.
Overall these prefetching techniques improved the runtime of large
benchmarks by 10-17x for these applications. More in the publication
_Reducing Seek Overhead with Application-Directed Prefetching_ in
USENIX ATC 2009 and at http://libprefetch.cs.ucla.edu/.

Still not fixed in 2.6.33-rc6. Takashi wrote that the fix was scheduled
for 2.6.33-rc6, but it did not appear. I have gone back to using the
workaround with 2.6.33-rc6.
