xtensa: fix stack frame size for NPTL
Cancellable syscalls use call8 to call functions that enable/disable cancellation, thus they cannot use the default FRAMESIZE. Redefine FRAMESIZE for such syscalls. This fixes the following testsuite failure: .... tst-mqueue8 FAIL tst-mqueue8 got 1 expected 0 going to cancel mq_receive in-time in-time mq_receive cancellation succeeded going to cancel mq_receive early Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
