If irq flags tracing is enabled the TRACE_IRQS_ON macros expands to a function call which clobbers registers %r0-%r5. The macro is used in the code path for single stepped system calls. The argument registers %r2-%r6 need to be restored from the stack before the system call function is called. Cc: stable@kernel.org Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> |
