From ee0c468bb151aad23281660152d2894f1e214238 Mon Sep 17 00:00:00 2001
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>

Subject: [PATCH] alpha: compile fixes
- jensen build: fix conflicting declarations for pci_alloc_consistent()
and undefined virt_to_phys();
- SMP: arch/alpha/kernel/smp.c:124: warning: passing argument 2
of '__cpu_test_and_set' discards qualifiers from pointer target type
Interestingly, this only happens with gcc-4.2; gcc <= 4.1 and gcc-4.3
are OK. Fixed with extra assignment.
