Merge tag 'for-linus-5.10b-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen updates from Juergen Gross:
- two small cleanup patches
- avoid error messages when initializing MCA banks in a Xen dom0
- a small series for converting the Xen gntdev driver to use
pin_user_pages*() instead of get_user_pages*()
- intermediate fix for running as a Xen guest on Arm with KPTI enabled
(the final solution will need new Xen functionality)
* tag 'for-linus-5.10b-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
x86/xen: Fix typo in xen_pagetable_p2m_free()
x86/xen: disable Firmware First mode for correctable memory errors
xen/arm: do not setup the runstate info page if kpti is enabled
xen: remove redundant initialization of variable ret
xen/gntdev.c: Convert get_user_pages*() to pin_user_pages*()
xen/gntdev.c: Mark pages as dirty
