[Qemu-devel] [PATCH 03/22] spapr: Use named enum for function remove_hpte

[Alexander Graf <agraf@suse.de>]

From: Stefan Weil <sw@weilnetz.de>

The function returned a target_ulong which was made from unnamed enum
values. The target_ulong was then assigned to an int variable which
was used in a switch statement.

Using a named enum in both cases makes reviews easier.
