[redhat] New configs in arch/powerpc
Hi,
As part of the ongoing rebase effort, the following configuration options need to be reviewed.
As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.
If the value for a file that is added should be changed, please reply with a better option.
CONFIG_CMDLINE:
On some platforms, there is currently no way for the boot loader to pass arguments to the kernel. For these platforms, you can supply some command-line options at build time by entering them here. In most cases you will need to specify the root device here.
Symbol: CMDLINE [=] Type : string Defined at arch/powerpc/Kconfig:882 Prompt: Initial kernel command string Location: -> Kernel options
CONFIG_PPC_QUEUED_SPINLOCKS:
Say Y here to use queued spinlocks which give better scalability and fairness on large SMP and NUMA systems without harming single threaded performance.
This option is currently experimental, the code is more complex and less tested so it defaults to "N" for the moment.
If unsure, say "N".
