sh: define __BIG_ENDIAN for math-emu

[ Upstream commit b929926f01f2d14635345d22eafcf60feed1085e ] Fix this by defining both ENDIAN macros in so that they can be utilized in according to the latter's comment: /* Allow sfp-machine to have its own byte order definitions. */ (This is what is done in arch/nds32/include/asm/sfp-machine.h.)

signal/sh: Use force_sig(SIGKILL) instead of do_group_exit(SIGKILL)

2021-11-18T18:17:03+00:00

[ Upstream commit ce0ee4e6ac99606f3945f4d47775544edc3f7985 ] Today the sh code allocates memory the first time a process uses the fpu. If that memory allocation fails, kill the affected task with force_sig(SIGKILL) rather than do_group_exit(SIGKILL). Calling do_group_exit from an exception handler can potentially lead to dead locks as do_group_exit is not designed to be called from interrupt context. Instead use force_sig(SIGKILL) to kill the userspace process. Sending signals in general and force_sig in particular has been tested from interrupt context so there should be no problems.
