Subject: [GIT PULL] Compute Express Link (CXL) Fixes for 6.15-rc4

Hi Linus, please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git cxl-fixes-6.15-rc4

...to receive a small set of CXL fixes.

The fixes address global persistent flush (GPF) changes and CXL Features
support changes that went in the 6.15 merge window. And also a fix to
an issue observed on CXL 1.1 platform during device enumeration.

These have all appeared in -next for a few days with no reported issues.
