Linus, Please git pull the following tag:
git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.10b-rc1b-tag xen: branch for v5.10-rc1b It contains the following: - A single patch for fixing the Xen security issue XSA-331 (malicious guests can DoS dom0 by triggering NULL-pointer dereferences or access to stale data). - A larger series for fixing the Xen security issue XSA-332 (malicious guests can DoS dom0 by sending events at high frequency leading to dom0's vcpus being busy in IRQ handling for elongated times). Thanks.
