BKL locking came to efirtc via the big BKL push down, but the access
to the efi functions is protected by efi_rtc_lock already.

Remove it.

Push it down as far as the EFI method calls.  Someone who knows EFI can do
the other bits.  Also fix another wrong unknown ioctl return.

Mark the static struct file_operations in drivers/char as const.  Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
