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
