Subject: Do not use the ia64 clocksource on non-ia64 architectures
X-Git-Tag: v2.6.23-rc5~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b2b64fd311c92f2137eb7cee7025794cd854057;p=pandora-kernel.git

Do not use the ia64 clocksource on non-ia64 architectures

The HPET clocksource in drivers/char/hpet.c was written as generic code
for ia64, but it is not yet ready to replace the native HPET clocksource
implementations that the i386/x86-64 architectures use.

On x86[-64], trying to register this clocksource results in potentially
multiple hpet-based clocksources being registered, and if the ia64 one
is chosen on x86_64 some users have experienced hangs.

Eventually all three architectures may end up using the same code, but
that is not the case right now.
