Teach idr_remove to accept failure.
But teach it to return the data if it succeeds too.

Define idr_init_base.
Nothing actually uses this at the moment, because callers already
specify the base. Not really sure what the point is!

Draft rewrite of idr preload.
Previous idr code assumed every caller would definitely call
idr_preload, idr_alloc, idr_preload_end, but some callers skip
idr_alloc if an intermediate failure happens
Draft rewrite of idr preload.
Previous idr code assumed every caller would definitely call
idr_preload, idr_alloc, idr_preload_end, but some callers skip
idr_alloc if an intermediate failure happens first, and would
therefore leak idr nodes.
Use a per-lwp single-node cache instead, and print warnings about
leakers.

Tweak slightly sketchy logic in linux_idr.
1. idr_preload can fail if you don't set __GFP_WAIT.
2. If idr_preload fails, it is wrong for idr_alloc to assert.
3. There is no way for idr_alloc to know
Tweak slightly sketchy logic in linux_idr.
1. idr_preload can fail if you don't set __GFP_WAIT.
2. If idr_preload fails, it is wrong for idr_alloc to assert.
3. There is no way for idr_alloc to know what flags idr_preload got.
Probably won't *fix* any bugs, but if there is a bug with a missing
__GFP_WAIT, then we will learn about a trifle sooner.

Make it build and boot on my test machines.
Screen blanks on boot on the Ivy Bridge system with
DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun
But after that everything is OK
Make it build and boot on my test machines.
Screen blanks on boot on the Ivy Bridge system with
DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun
But after that everything is OK. Appears to be an upstream problem.
To investigate...
I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.
