Subject: [GIT PULL] x86/sgx for 6.19-rc1

Hi Linus,

Please pull some x86/sgx changes for 6.19-rc1. The main content here
is adding support for the new EUPDATESVN SGX ISA. Before this, folks
who updated microcode had to reboot before enclaves could attest to
the new microcode. The new functionality lets them do this without a
reboot.

The rest are some nice, but relatively mundane comment and kernel-doc
fixups.
