x86, um: sanitize uml sigcontext.h uses

2008-10-23T05:55:20Z

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 Signed-off-by: H. Peter Anvin

uml: remove the dead TTY_LOG code

kernel/cpu.c: create a CPU_STARTING cpu_chain notifier

2008-09-08T17:25:24Z

Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.

um: use generic show_mem()

2008-07-26T19:00:10Z

Remove arch-specific show_mem() in favor of the generic version. This also removes the following redundant information display: - free swap pages, printed by show_swap_cache_info() - pages in swapcache, printed by show_swap_cache_info() where show_mem() calls show_free_areas(), which calls show_swap_cache_info().

UML: make several more things static

2008-07-24T17:47:24Z

- Make some variables and functions static, since they don't need to be global. - Remove an unused function - arch/um/kernel/time.c::sched_clock(). - Clean the style a bit as complained by checkpatch.pl.

arch/um/kernel/mem.c: remove arch_validate()

2008-07-24T17:47:24Z

- Remove arch_validate(), because no one uses it. - Remove useless macro HAVE_ARCH_VALIDATE. - Make the variable 'empty_bad_page' static. Cc: Jeff Dike Signed-off-by: WANG Cong Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

arch/um/kernel/irq.c: clean up some functions

2008-07-24T17:47:24Z

Make activate_fd() and free_irq_by_irq_and_dev() static. Remove init_aio_irq() since it has no users. Cc: Jeff Dike Signed-off-by: WANG Cong Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
