sys/i386/i386 genassym.c locore.s machdep.c support.s
sys/i386/include md_var.h sigframe.h ucontext.h
Log:
Simplification of the signal trampoline and other cleanups.
o Remove unused defines from genassym.c that were needed
by the trampoline.
o Add load_gs_param function to support.s that catches
a fault when %gs is loaded with an invalid descriptor.
The function returns EFAULT in that case.
o Remove struct trapframe from mcontext_t and replace it
with the list of registers.
o Modify sendsig and sigreturn accordingly.
This commit contains a patch by bde.
