Subject: [PATCH] alpha: support R_ALPHA_REFLONG relocations for module loading
Date: Sat, 24 Jun 2017 13:37:02 +1200	[thread overview]
Message-ID: <20170624013702.18225-1-mcree@orcon.net.nz> (raw)

Since commit 71810db27c1c853b33 (modversions: treat symbol CRCs
as 32 bit quantities) R_ALPHA_REFLONG relocations can be required
to load modules. This implements it.
