The kernel does not require PROT_READ for addresses passed to mincore.

v1: https://lore.kernel.org/qemu-devel/20230416195103.607948-1-thomas@t-8ch.de/
v1 -> v2:
* Introduce symbolic flag VERIFY_NONE instead of hardcoding "0"

Thomas Weißschuh (2):
  linux-user: Add new flag VERIFY_NONE
  linux-user: Don't require PROT_READ for mincore
