2009-09-24sh: Fix up uninitialized variable use caught by gcc 4.4.Paul Mundt1-6/+6
In the unaligned kernel exception fixup case the printk() was ordered before the copy_from_user(), resulting in a nonsensical instruction value. This fixes up the ordering properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-09-24sh: Handle unaligned 16-bit instructions on SH-2A.Paul Mundt1-3/+8
This adds some sanity checking in the unaligned instruction handler to verify the instruction size, which enables basic support for 16-bit fixups on SH-2A parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* remove asm/atomic.h inclusion from linux/utsname.h -- not needed after kref conversion * remove linux/utsname.h inclusion from files which do not need it NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however due to some personality stuff it _is_ needed -- cowardly leave ELF-related headers and files alone.

2009-09-23Revert "kmod: fix race in usermodehelper code"Sebastian Andrzej Siewior1-8/+5
This reverts commit c02e3f361c7 ("kmod: fix race in usermodehelper code") The patch is wrong. UMH_WAIT_EXEC is called with VFORK what ensures that the child finishes prior returing back to the parent. No race. In fact, the patch makes it even worse because it does the thing it claims not do: - It calls ->complete() on UMH_WAIT_EXEC - the complete() callback may de-allocated subinfo as seen in the following call chain: [<c009f904>] (__link_path_walk+0x20/0xeb4) from [<c00a094c>] (path_walk+0x48/0x94) [<c00a094c>] (path_walk+0x48/0x94) from [<c00a0a34>] (do_path_lookup+0x24/0x4c) [<c00a0a34>] (do_path_lookup+0x24/0x4c) from [<c00a158c>] (do_filp_open+0xa4/0x83c) [<c00a158c>] (do_filp_open+0xa4/0x83c) from [<c009ba90>] (open_exec+0x24/0xe0) [<c009ba90>] (open_exec+0x24/0xe0) from [<c009bfa8>] (do_execve+0x7c/0x2e4) [<c009bfa8>] (do_execve+0x7c/0x2e4) from [<c0026a80>] (kernel_execve+0x34/0x80) [<c0026a80>] (kernel_execve+0x34/0x80) from [<c004b514>] (____call_usermodehelper+0x130/0x148) [<c004b514>] (____call_usermodehelper+0x130/0x148) from [<c0024858>] (kernel_thread_exit+0x0/0x8) and the path pointer was NULL. Good that ARM's kernel_execve() doesn't check the pointer for NULL or else I wouldn't notice it. The only race there might be is with UMH_NO_WAIT but it is too late for me to investigate it now. UMH_WAIT_PROC could probably also use VFORK and we could save one exec. So the only race I see is with UMH_NO_WAIT and recent scheduler changes where the child does not always run first might have trigger here something but as I said, it is late....

2009-09-24cpumask: remove unused deprecated functions, avoid accusations of insanityRusty Russell1-111/+1
We're not forcing removal of the old cpu_ functions, but we might as well delete the now-unused ones. Especially CPUMASK_ALLOC and friends. I actually got a phone call (!) from a hacker who thought I had introduced them as the new cpumask API. He seemed bewildered that I had lost all taste.

2009-09-24cpumask: remove unused mask field from struct irqaction.Rusty Russell1-1/+0
Up until 1.1.83, the primitive human tribes used struct sigaction for interrupts. The sa_mask field was overloaded to hold a pointer to the name. When someone created the new "struct irqaction" they carried across the "mask" field as a kind of ancestor worship: the fact that it was unused makes clear its spiritual significance.

2009-09-24cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL.: mipsRusty Russell1-1/+1
(Thanks to Al Viro for reminding me of this, via Ingo) CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so: #define CPU_MASK_ALL (cpumask_t) { { ... } } Taking the address of such a temporary is questionable at best, unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added CPU_MASK_ALL_PTR: #define CPU_MASK_ALL_PTR (&CPU_MASK_ALL) Which formalizes this practice. One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real struct cpumask *), and remove CPU_MASK_ALL_PTR altogether.
