Patches that were posted last week - with review comments addressed.

Hi all: This series introduce basic functionality of doorbell mapping support for vhost-vDPA. Userspace program may use mmap() to map a the doorbell of a specific virtqueue into its address space. This is help to reudce the syscall or vmexit overhead. A new vdpa_config_ops was introduced to report the location of the doorbell, vhost_vdpa may then choose to map the doorbell when: - The doorbell

This patchset applies to klibc mainline. As is it will probably collide with Maximilian's recent patch to rename run-init to switch_root posted last week. To boot an untrusted environment with certain capabilities locked out, we'd like to be able to drop the capabilities up front from early userspace, before we actually transition onto the root volume. This patchset implements this by
