[Xen-devel] [PATCH 3/9] xen/arm: traps: Data Abort are always unconditional

[Julien Grall <julien.grall@xxxxxxx>]

The HSR encoding for an exception from a data abort does not contain a
conditional code (see G6-4264 in ARM DDI 0487A.i) because they are
always conditional.

So drop the pointless condition check.
