Subject: [PATCH] hvf: arm: Do not advance PC when raising an exception
|
|
cherry-pick from 30a1690f2402e6c1582d5b3ebcf7940bfe2fad4b
|
|
|
|
hvf did not advance PC when raising an exception for most unhandled
|
|
system registers, but it mistakenly advanced PC when raising an
|
|
exception for GICv3 registers.
