[Qemu-devel] [PULL 01/22] translate-all: use glib for all page descriptor allocations

[Paolo Bonzini <pbonzini@redhat.com>]

From: "Emilio G. Cota" <cota@braap.org>

Since commit

  b7b5233a "bsd-user/mmap.c: Don't try to override g_malloc/g_free"

the exception we make here for usermode has been unnecessary.
Get rid of it.
