Subject: [IA64] Use atomic64_read to read an atomic64_t.
X-Git-Tag: v2.6.23-rc4~124^2~13
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6cba986298105a87a09d65baa2658fb5111459c6;p=linux-2.6

[IA64] Use atomic64_read to read an atomic64_t.

The routines ia64_atomic64_{add,sub} mistakenly use
atomic_read() to grab the old value instead of using
atomic64_read().
