xsm: refactor IO hooks/sysctl hooks
- The patch refactors the IO resource checks into the rangeset add/del
code. This produces a much more architecture friendly implementation and
ensures that HVM and paravirtualized guests are checked consistently.
- The patch removes the following hooks in support of the refactoring
of the IO resource checks:
- xsm_irq_permission
- xsm_iomem_permission
- xsm_ioport_permission
- The patch adds the following hooks in support of the refactoring of
the IO resource checks:
- xsm_add_range
- xsm_remove_range
- These IO refactoring changes are transparent to any pre-existing
Flask policies.
- The patch adds also adds hooks for sysctl functionality that was
added since the last major XSM patch. The following hooks were added:
- xsm_set_target
- xsm_debug_keys
- xsm_getcpuinfo
- xsm_availheap
- xsm_firmware_info
- xsm_acpi_sleep
- xsm_change_freq
- xsm_getidletime
- xsm_sendtrigger
- xsm_test_assign_device
- xsm_assign_device
- xsm_deassign_device
- xsm_bind_pt_irq
- xsm_pin_mem_cacheattr
- xsm_ext_vcpucontext
