s390/traps: Fix test_monitor_call() inline assembly

s390/traps: Fix test_monitor_call() inline assembly

commit 5623bc23a1cb9f9a9470fa73b3a20321dc4c4870 upstream.

The test_monitor_call() inline assembly uses the xgr instruction, which
also modifies the condition code, to clear a register. However the clobber
list of the inline assembly does not specify that the condition code is
modified, which may lead to incorrect code generation.

Use the lhi instruction instead to clear the register without that the
condition code is modified. Furthermore this limits clearing to the lower
32 bits of val, since its type is int.

s390/traps: improve panic message for translation-specification exception

There are many different types of translation exceptions but only a
translation-specification exception leads to a kernel panic since it
indicates corrupted page tables, which must never happen.

Improve the panic message so it is a bit more obvious what this is about.
