um: Increase stack frame size threshold for signal.c
The signal.c can't use heap for bit data located on stack. However, by default a compiler warns us about overstepping stack frame size threshold: arch/um/os-Linux/signal.c: In function ‘sig_handler_common’: arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] 51 | } | ^ arch/um/os-Linux/signal.c: In function ‘timer_real_alarm_handler’: arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] 95 | } | ^ Due to above increase stack frame size threshold explicitly for signal.c to avoid unnecessary warning.
