Pull timer updates from Thomas Gleixner. Various trivial conflict fixups in arch Kconfig due to addition of unrelated entries nearby. And one slightly more subtle one for sparc32 (new user of GENERIC_CLOCKEVENTS), fixed up as per Thomas. * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits) timekeeping: Fix a few minor newline issues. time: remove obsolete declaration ntp: Fix a stale comment and a few stray newlines. ntp: Correct TAI offset during leap second timers: Fixup the Kconfig consolidation fallout x86: Use generic time config unicore32: Use generic time config um: Use generic time config tile: Use generic time config sparc: Use: generic time config sh: Use generic time config score: Use generic time config s390: Use generic time config openrisc: Use generic time config powerpc: Use generic time config mn10300: Use generic time config mips: Use generic time config microblaze: Use generic time config m68k: Use generic time config m32r: Use generic time config ...

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
