The old idr code was really a second radix tree implementation - we
already have one in lib/radix-tree.c.
This patch reimplements idr on top of our existing radix trees, using
our shiny new ida implementation for allocating/freeing the ids. The old
idr code was noticably slower than lib/radix-tree
get() implies taking a ref or sometimes an allocation, which this
function definitely does not do - rename it to something more sensible.

Even if I am right the problem is really minor, the patch should
be ignored without the authoritative acks.
I am only sending it because I am curious, and I would like to ask

I can't understand if th
If audit_filter_task() nacks the new thread it makes sense
to clear TIF_SYSCALL_AUDIT which can be copied from parent

A wrong TIF_SYSCALL_AUDIT is not really bad, but it triggers
the "slow" audit paths in entry.S.

This set breaks out some common code from x86/ia64 EFI support
code and puts it into drivers/firmware/efi.
First it takes the definition of the global "efi" data structure
and moves it into global efi.c. Then it implements a common version
of efi_config_init().
Secondly it breaks the efi_lookup_m

Common to (U)EFI support on all platforms is the global "efi" data

addresses to populate that structure with.
This patch adds both of these to the global EFI driver code.

So 'perf trace' has a similar option:

Well we do... both to extract relocations and to sort the exception table.
Perhaps we need to merge those kinds of postprocessing tools?

That's mighty permissive :(
For a demo it might be OK.
BUT: I think I should modify the module to forward a close request

If we can do this generically and without adding 500 lines of
specialized code, my argument obvious

The real rule is that if the scheduler does its outermost rcu_read_unlock()
with one of those locks held, it has to
