You'll definitely need to make this work dynamically

No - as noted, not all mempolicy system calls go via libnuma.
Well then show me.
No current version of libcpuset is available.
Wrong. It has not received wide

Hi,
I'd like to propose these patches for the x86 tree for a bit more exposure
and testing. Or at least get some discussion going again.
Just for fun I also had a shot at merging the headers, as they become a
lot more similar after this with the removal of the paravirt crud.

The break_lock data structure and code for spinlocks is quite nasty.
Not only does it double the size of a spinlock but it changes locking to
a potentially less optimal trylock.
Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a
__raw_spin_is_contended that uses the lock data itself
Introduce ticket lock spinlocks for x86 which are FIFO. The implementation
is described in the comments. The straight-line lock/unlock instruction
sequence is slightly slower than the dec based locks on modern x86 CPUs,
however the difference is quite small on Core2 and Opteron when working out
Prepare for merging 32 and 64 bit spinlocks, by making them identical
(except for the OOSTORE thing). raw_read_lock and raw_write_lock get a
relaxed register constraint, and 64-bit has a few =m constraints changed
to +m. I hope these things actually make the code better.

We are both half-right. I reverted my version of that completely,
applied your version verbatim, and pushed it upstream. The result:
atapi_xlat _did_ start programming lbam/lbah for DMA (another behavior

Hi!
Remove the need for having CAP_SYS_RAWIO when doing a FIBMAP call on an open
file descriptor.
It would be nice to allow users to have permission to see where their data is
landing on disk, and there really isn't a good reason to keep them from
getting at this information.
