um: Increase stack frame size threshold for signal.c

2020-12-13T21:22:00Z

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.

um: Support kcov

2016-08-03T22:18:06Z

This adds support for kcov to UML. There is a small problem where UML will randomly segfault during boot; this is because current_thread_info() occasionally returns an invalid (non-NULL) pointer and we try to dereference it in __sanitizer_cov_trace_pc(). I consider this a bug in UML itself and this patch merely exposes it.

um: merge os-Linux/tls.c into arch/x86/um/os-Linux/tls.c

it's i386-specific; moreover, analogs on other targets have incompatible interface - PTRACE_GET_THREAD_AREA does exist elsewhere, but struct user_desc does *not* Signed-off-by: Al Viro Signed-off-by: Richard Weinberger
