BUILD_BUG_ON(1) is asking for trouble (and getting it) when used in that manner - dead code elimination happens after we parse it and invalid type is invalid type, dead code or not. It might be version-dependent, but at least 4.0.1 refuses to accept that. Signed-off-by:

Switched cpuset_common_file_read() to simple_read_from_buffer(), killed a bunch of useless (and not quite correct - e.g. min(size_t,ssize_t)) code. Signed-off-by:

Patch from Gen FUKATSU Invalidate BTB entry instruction flushes two instruction at a time. Therefore this instruction should be done four times after invalidate instruction cache line. Signed-off-by: Gen Fukatsu Signed-off-by:

Patch from Catalin Marinas When CONFIG_CPU_CACHE_VIPT is defined, the flush_pfn_alias() function is implicitely declared and it later conflicts with its actual definition. This patch moves the function definition to the beginning of the file. Signed-off-by:

Patch from Daniel Jacobowitz Thread flags are inherited on fork(). In order for a binary which has the iWMMXt coprocessor enabled to run a binary which needs the FPA emulation, we need to explicitly clear TIF_USING_IWMMXT if we are not going to set it. Signed-off-by:

The SMU driver has a small mistake in the locking of the interrupt code, if polled access and interrupt access race, interrupt may take a lock and return without releasing it. This fixes it. With that patch, the driver is rock solid with my experimental thermal control (which bangs it pretty hard) racing with real time clock and cpufreq handling. Signed-off-by:

it seems that readv(2)/writev(2) syscalls do not call file_permission callback. Looks like this is overlook. I have filled the issue into redhat bugzilla as https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169433 and got the recommendation to post this on lsm mailing list. The following trivial patch solves the problem. Signed-off-by:

The attempt to fixup the lockless mce log buffer introduced an infinite loop when trying to find a free entry. And: Using rcu_dereference() to load mcelog.next doesn't seem to be sufficient enough to ensure that mcelog.next is loaded each time around the loop in mce_log(). Instead, use an explicit rmb() to ensure that the compiler gets it right. AK: turned the smp_wmbs into true wmbs to make sure they are not reordered by the compiler on UP. Signed-off-by:

Any tests using < TASK_STOPPED or the like are left over from the time when the TASK_ZOMBIE and TASK_DEAD bits were in the same word, and it served to check for "stopped or dead". I think this one in do_signal_stop is the only such case. It has been buggy ever since exit_state was separated, and isn't testing the exit_state value. Signed-off-by:

Roland points out that the flags end up having non-obvious dependencies elsewhere, so revert aa55a086 and add some comments about why things are as they are. We'll just have to fix up the broken comparisons. Roland has a patch. Signed-off-by:

do_signal_stop: for_each_thread(t) { if (t->state < TASK_STOPPED) ++sig->group_stop_count; } However, TASK_NONINTERACTIVE > TASK_STOPPED, so this loop will not count TASK_INTERRUPTIBLE | TASK_NONINTERACTIVE threads. See also wait_task_stopped(), which checks ->state > TASK_STOPPED. Signed-off-by:Oleg Nesterov <oleg@tv-sign.ru> [ We really probably should always use the appropriate bitmasks to test task states, not do it like this. Using something like #define TASK_RUNNABLE (TASK_RUNNING | TASK_INTERRUPTIBLE | \ TASK_UNINTERRUPTIBLE | TASK_NONINTERACTIVE) and then doing "if (task->state & TASK_RUNNABLE)" or similar. But the ordering of the task states is historical, and keeping the ordering does make sense regardless. ] Signed-off-by:

In arch/ppc/boot/ld.script we need OUTPUT_ARCH(powerpc:common) for the same reasons why we need it in vmlinux.lds.S; when we build on ppc64 box, we need to be explicit about the target. See http://linus.bkbits.net:8080/linux-2.5/cset@1.1784.8.10 for the corresponding fix in vmlinux.lds.S. Signed-off-by:

UML makefiles sanitized: - number of generated headers reduced to 2 (from user-offsets.c and kernel-offsets.c resp.). The rest is made constant and simply includes those two. - mk_... helpers are gone now that we don't need to generate these headers - arch/um/include2 removed since everything under arch/um/include/sysdep is constant now and symlink can point straight to source tree. - dependencies seriously simplified.
