[PATCH v2 0/7] MPU mm subsystem skeleton

[Luca Fancellu <luca.fancellu@xxxxxxx>]

Hi all,

this serie implements the skeleton for the MPU memory management subsystem,
at the end of the serie it will be possible to compile the Arm64 arch using MPU.

The minimum Arm Kconfig configuration is this one:

CONFIG_UNSUPPORTED=y
CONFIG_MPU=y
CONFIG_XEN_START_ADDRESS=0x0


Luca Fancellu (5):
  arm/mpu: Add HYPERVISOR_VIRT_START and avoid a check in xen.lds.S
  xen/arm: Introduce frame_table and virt_to_page
  arm/mpu: Kconfig symbols for MPU build
  arm/mpu: Implement stubs for ioremap_attr on MPU
  arm/mpu: Create the skeleton for MPU compilation

Penny Zheng (2):
  xen/arm: Implement virt/maddr conversion in MPU system
  xen: introduce Kconfig HAS_PAGING_MEMPOOL
