2012-03-23um: use set_current_blocked() and block_sigmask()Matt Fleming1-14/+6
As described in commit e6fa16ab9c1e ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

2012-03-23um: don't restore current->blocked on errorMatt Fleming1-6/+2
If we fail to setup the signal stack frame then we don't need to restore current->blocked because it is not modified by setup_signal_stack_*.

2008-10-22x86, um: sanitize uml sigcontext.h usesAl Viro1-1/+1
a) the only difference between sigcontext and sysdep/sigcontext is that the former contains externs for two long-dead functions. Removed, switched the only user to sysdep/sigcontext b) asm/sigcontext.h is removable - that of underlying architecture would get used. Signed-off-by: Al Viro <[email protected]> Signed-off-by: H.

2008-02-05uml: style fixes in arch/um/kernelJeff Dike1-8/+8
Joe Perches noticed some printks in smp.c that needed fixing. While I was in there, I did the usual tidying in arch/um/kernel, which should be fairly style-clean at this point: copyright updates emacs formatting comments removal include tidying style fixes Cc: Joe Perches <[email protected]> Signed-off-by: Jeff Dike <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2007-10-16uml: style fixes pass 3Jeff Dike1-32/+26
Formatting changes in the files which have been changed in the course of folding foo_skas functions into their callers. These include: copyright updates header file trimming style fixes adding severity to printks These changes should be entirely non-functional.

2007-10-16uml: remove code made redundant by CHOOSE_MODE removalJeff Dike1-1/+0
This patch makes a number of simplifications enabled by the removal of CHOOSE_MODE. There were lots of functions that looked like int foo(args){ foo_skas(args); } The bodies of foo_skas are now folded into foo, and their declarations (and sometimes entire header files) are deleted. In addition, the union uml_pt_regs, which was a union between the tt and skas register formats, is now a struct, with the tt-mode arm of the union being removed. It turns out that usr2_handler was unused, so it is gone.

2006-07-10[PATCH] uml: move _kern.c filesJeff Dike1-0/+191
Move most *_kern.c files in arch/um/kernel to *.c. This makes UML somewhat more closely resemble the other arches.
