[Qemu-devel] [PATCH] target-arm: Avoid g_hash_table_get_keys()

[Peter Maydell <peter.maydell@linaro.org>]

g_hash_table_get_keys() was only introduced in glib 2.14, and we're
still targeting a minimum version of 2.12.  Rewrite the offending
code (introduced in commit 721fae1) to use g_hash_table_foreach()
to build the list of keys.
