arm64: die(): pass 'err' as long
commit 18906ff9af6517c20763ed63dab602a4150794f7 upstream.
Recently, we reworked a lot of code to consistentlt pass ESR_ELx as a
64-bit quantity. However, we missed that this can be passed into die()
and __die() as the 'err' parameter where it is truncated to a 32-bit
int.
As notify_die() already takes 'err' as a long, this patch changes die()
and __die() to also take 'err' as a long, ensuring that the full value
of ESR_ELx is retained.
At the same time, die() is updated to consistently log 'err' as a
zero-padded 64-bit quantity.
Subsequent patches will pass the ESR_ELx value to die() for a number of
exceptions.
