* rwsem: fully separate code paths to wake writers vs readersMichel Lespinasse2010-08-09
| | | | | | | | | | | | | | | | | | | | | | This is in preparation for later changes in the series. In __rwsem_do_wake(), the first queued waiter is checked first in order to determine whether it's a writer or a reader. The code paths diverge at this point. The code that checks and increments the rwsem active count is duplicated on both sides - the point is that later changes in the series will be able to independently modify both sides.

* hwmon: f71882fg: add support for the Fintek F71808EGiel van Schijndel2010-08-09
| | | | | | | | | | | | | | | | | | | | | | Allow device probing to recognise the Fintek F71808E. Sysfs interface: * Fan/pwm control is the same as for F71889FG * Temperature and voltage sensor handling is largely the same as for the F71889FG - Has one temperature sensor less (doesn't have temp3) - Misses one voltage sensor (doesn't have V6, thus in6_input refers to what in7_input refers for F71889FG) For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up such that it can largely be reused.

Because even none of online cpus supports coretemp, we can't assume new onlined cpu doesn't support it either. If related driver is unregistered there we have no chance to use coretemp from then on.

* checkpatch: fix extraneous EXPORT_SYMBOL* warningsPatrick Pannuto2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are caused by checkpatch incorrectly parsing its internal representation of a statement block for struct's (or anything else that is a statement block encapsulated in {}'s that also ends with a ';'). Fix this by properly parsing a statement block. An example: +struct dummy_type dummy = { + .foo = "baz", +}; +EXPORT_SYMBOL_GPL(dummy); + +static int dummy_func(void) +{ + return -EDUMMYCODE; +} +EXPORT_SYMBOL_GPL(dummy_func); WARNING: EXPORT_SYMBOL(foo); should immediately \ follow its function/variable #19: FILE: dummy.c:4: +EXPORT_SYMBOL_GPL(dummy); The above warning is issued when it should not be.

Most of the drivers don't check the return value of misc_deregister(). (It is not bad thing because most of kernel *_unregister() API always succeed and do not return value) So it is better to indicate the error by WARN_ON() in misc_deregister().

* x86, ia64, smp: use workqueues unconditionally during do_boot_cpu()Suresh Siddha2010-08-09
| | | | | | | | | | | | | | | Workqueues are now initialized as part of the early_initcall(). So they are available for use during cold boot process aswell.

* init/main.c: mark do_one_initcall* as __init_or_moduleKevin Winchester2010-08-09
| | | | | | | | | | | | Andrew Morton suggested that the do_one_initcall and do_one_initcall_debug functions can be marked __init_or_module such that they can be discarded for the CONFIG_MODULES=N case.

* init/main.c: fix warning: 'calltime.tv64' may be used uninitializedKevin Winchester2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | Using: gcc (GCC) 4.5.0 20100610 (prerelease) The following warning appears: init/main.c: In function `do_one_initcall': init/main.c:730:10: warning: `calltime.tv64' may be used uninitialized in this function This warning is actually correct, as the global initcall_debug could arguably be changed by the initcall. Correct this warning by extracting a new function, do_one_initcall_debug, that performs the initcall for the debug case.
