Merge tag 'for-linus-6.7a-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
- A small cleanup patch for the Xen privcmd driver
- A fix for the swiotlb-xen driver which was missing the advertising of
the maximum mapping length
- A fix for Xen on Arm for a longstanding bug, which happened to occur
only recently: a structure in percpu memory crossed a page boundary,
which was rejected by the hypervisor
* tag 'for-linus-6.7a-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
arm/xen: fix xen_vcpu_info allocation alignment
xen: privcmd: Replace zero-length array with flex-array member and use __counted_by
swiotlb-xen: provide the "max_mapping_size" method
