And if you try to look this up, you'll notice that I typed it wrong.
It's IA32_SGXLEPUBKEYHASH. Whoops.

There's no way to get here with 'err != 0'. Just return 0 to be more
obvious and prevent future changes from accidentally erroring out here
without going through the right error paths.

The regulator framework can return negative error codes via
regulator_get_current_limit() for regulators that don't provide current
information. The subsequent check for postive values isn't very useful,
if the variable is unsigned.
Let's just match the signedness of the return value.

I haven't quite figured out the right way to invert pci_remap_iospace().
I guess no one supports this yet? So currently, if you try to
remove/re-probe we'll hit a BUG() in ioremap code when we call this a
second time.
I post the unfinished work here as a bug repo

Hi all,
This patch series implements a new transport for 9pfs, aimed at Xen
systems.
The transport is based on a traditional Xen frontend and backend drivers
pair. This patch series implements the frontend, which typically runs in
a regular unprivileged guest.
I also sent a series that implement
Upon receiving a notification from the backend, schedule the
p9_xen_response work_struct. p9_xen_response checks if any responses are
available, if so, it reads them one by one, calling p9_client_cb to send
them up to the 9p layer (p9_client_cb completes the request). Handle the
