2014-01-13drivers/char: don't use module_init in non-modular ttyprintk.cPaul Gortmaker
The TTY_PRINTK option is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.

2014-01-13x86, microcode, AMD: Fix early ucode loadingBorislav Petkov
The original idea to use the microcode cache for the APs doesn't pan out because we do memory allocation there very early and with IRQs disabled and we don't want to involve GFP_ATOMIC allocations. Not if it can be helped. Thus, extend the caching of the BSP patch approach to the APs and iterate over the ucode in the initrd instead of using the cache. We still save the relevant patches to it but later, right before we jettison the initrd. While at it, fix early ucode loading on 32-bit too.

2014-01-13perf probe: Fix build when DWARF support libraries not presentArnaldo Carvalho de Melo
On a freshly installed system, after libelf-dev is installed we get: CC /tmp/build/perf/util/probe-event.o util/probe-event.c: In function ‘try_to_find_probe_trace_events’: util/probe-event.c:753:46: error: unused parameter ‘target’ [-Werror=unused-parameter] int max_tevs __maybe_unused, const char *target) ^ CC /tmp/build/perf/util/cgroup.o util/probe-event.c: At top level: util/probe-event.c:193:12: error: ‘get_text_start_address’ defined but not used [-Werror=unused-function] static int get_text_start_address(const char *exec, unsigned long *address) ^ cc1: all warnings being treated as errors make[1]: *** [/tmp/build/perf/util/probe-event.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [install] Error 2 Fix it by enclosing functions only used when those libraries are installed under the suitable preprocessor define and using __maybe_unused to a function that is only built when DWARF support is disabled.
