Subject: [PATCH] Add 64bit jiffies compares (for use with get_jiffies_64)
X-Git-Tag: v2.6.19-rc1~1077^2~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b171672831b9633c2ed8fa94805255cd4d5af19;p=pandora-kernel.git

[PATCH] Add 64bit jiffies compares (for use with get_jiffies_64)

The current time_before/time_after macros will fail typechecks
when passed u64 values (as returned by get_jiffies_64()). On 64bit
systems, this will just result in a warning about mismatching types
without explicit casts, but since unsigned long and u64
(unsigned long long) are of same size, it will still work.
On 32bit systems, a long is 32bits, so the value from get_jiffies_64()
will be truncated by the cast and thus lose all the precision gained by
64bit jiffies.
