Subject: [PATCHES] uaccess hpsa

	hpsa compat ioctl done (hopefully) saner.  I really want
to kill compat_alloc_user_space() off - it's always trouble and
for a driver-private ioctls it's absolutely pointless.

	Note that this is only compile-tested - I don't have the
hardware to test it on *or* userland to issue the ioctls in
question.  So this series definitely needs a review and testing
from hpsa maintainers before it might go anywhere.

	The series is in vfs.git #uaccess.hpsa, based at v5.7-rc1

Al Viro (4):
      hpsa passthrough: lift {BIG_,}IOCTL_Command_struct copy{in,out} into hpsa_ioctl()
      hpsa: don't bother with vmalloc for BIG_IOCTL_Command_struct
      hpsa: get rid of compat_alloc_user_space()
      hpsa_ioctl(): tidy up a bit
