[Xen-devel] [PATCH v2 1/4] arm: processor: rename iss to res0 in hsr_cond union

Name "iss" in this case was used not exactly correctly, because this
is only part of HSR.ISS field. ARM refence manual denotes this
part of ISS as RES0 when it describes encoding for conditional
exceptions (ARM DDI 0487A.k pages D7-1939 - D7-1949).

Signed-off-by: Volodymyr Babchuk <volodymyr_babchuk@xxxxxxxx>

- Added reference to ARM archtecture manual in the commit message.
