	sys/arch/amd64/amd64/trap.c:   revision 1.95-1.96	(patch)

Remove the osyscall call gate and emulate it. There is a
one-instruction race in it that could panic the kernel.

Restore the ability to run netbsd 1.0 32-bit executables by checking
for the relevant lcall instruction in the trap handler and treating it
as a syscall.

	sys/arch/i386/i386/locore.S: revision 1.103
in osyscall, set the PSL_I bit into the correct field of the trapframe.
it was going into tf_eip instead of tf_eflags, which would sometimes
corrupt %eip and always return to user mode with interrupts disabled.
this was found with a netbsd 1.0 binary, and dsl@ points out that
this should also fix PR 41342.
