[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_PPC_PROT_SAO_LPAR:

This option adds support for PROT_SAO mappings from userspace inside LPARs on supported CPUs.

This may cause issues when performing guest migration from a CPU that supports SAO to one that does not.

If unsure, say N here.

Symbol: PPC_PROT_SAO_LPAR [=n] Type : bool Defined at arch/powerpc/Kconfig:863 Prompt: Support PROT_SAO mappings in LPARs Depends on: PPC_BOOK3S_64 [=y] Location: -> Kernel options

Hi Steve,

Sorry to bother, but do you have any comment on this option?
