[redhat] New configs in arch/x86

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_X86_SGX:

Intel(R) Software Guard eXtensions (SGX) is a set of CPU instructions that can be used by applications to set aside private regions of code and data, referred to as enclaves. An enclave's private memory can only be accessed by code running within the enclave. Accesses from outside the enclave, including other enclaves, are disallowed by hardware.

If unsure, say N.

Symbol: X86_SGX [=n] Type : bool Defined at arch/x86/Kconfig:1937 Prompt: Software Guard eXtensions (SGX) Depends on: X86_64 [=y] && CPU_SUP_INTEL [=y] && CRYPTO [=y]=y && CRYPTO_SHA256 [=y]=y Location: -> Processor type and features Selects: SRCU [=y] && MMU_NOTIFIER [=y]
