Also remove all parts of the string table (referenced by the symbol table) that are not needed for kallsyms use (i.e. which were only referenced by symbols discarded by the previous patch, or not referenced at all for whatever reason).

* 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.

This reverts commit c02e3f36 ("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....

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.

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.

(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.
