This patch fixes a build bug on m68k - gcc decides to emit a call to the strlen library function, which we don't implement. More importantly - my previous patch "init: don't lose initcall return values" (commit e662e1cf) had introduced potential buffer overflow by wrong calculation of string accumulator size. Use strlcat() instead, fixing both bugs. Many thanks Andreas Schwab and Geert Uytterhoeven for helping to catch and fix the bug.

Everybody wants to pass it a function pointer, and in fact, that is what you _must_ pass it for it to make sense (since it knows that ia64 and ppc64 use descriptors for function pointers and fetches the actual address from there). So don't make the argument be a 'unsigned long' and force everybody to add a cast. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The patch aims to fix a performance issue for the syscall personality(PER_LINUX32). On IA-64 box, the syscall personality (PER_LINUX32) has poor performance because it failed to find the Linux/x86 execution domain. Then it tried to load the kernel module however it failed always and it used the default execution domain PER_LINUX instead. Requesting kernel modules is very expensive. It caused the performance issue. (see the function lookup_exec_domain in kernel/exec_domain.c). To resolve the issue, execution domain Linux/x86 is always registered in initialization time for IA-64 architecture.

Both smp_call_function() and __smp_call_function_map() access cpu_online_map. Both functions run with preemption disabled which protects for cpus going offline. However new cpus can be added and therefore the cpu_online_map can change unexpectedly.

Calls to copy_to_user() or copy_from_user() can fail when copying N bytes, where N is a constant less than 8, but not 1, 2, 4, or 8, because 'ret' is not initialized and is only set if the size is 1, 2, 4 or 8, but is tested after the switch statement for any constant size <= 8. This fixes it by initializing 'ret' to 1, causing the code to fall through to the __copy_tofrom_user call for sizes other than 1, 2, 4 or 8.
