# Merge: 4907a43da831 32118f97f41d
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Wed Oct 14 10:34:45 2020 -0700
# 
#     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*()
