There is a couple of assembly functions, which are invoked only locally
in the file they are defined. In C, we mark them "static". In assembly,

Introduce new C macros for annotations of functions and data in

Here, we change all code which is not marked as functions. In other
words, this code has been using END, not ENDPROC. So switch all of this
to appropriate new markings SYM_CODE_START and SYM_CODE_END.

This avoids indirection and parameter constraint issues. Doing so relaxes the
load_LDT() constraints from %ax to any general purpose register.
The triple-fault reboot method stays as is, to avoid the int3 possibly getting
moved relative to the lidt.

When doing a live migration of a Xen guest with libxl, the images for
block devices are locked by the original QEMU process, and this prevent
the QEMU at the destination to take the lock and the migration fail.

We should consider the early boot period to end when we stop using the
boot allocator. This is inline with x86 and will be helpful to know
whether we should allocate memory from the boot allocator or xenheap.

Currently, it is not possible to specify the permission of a new

with a different set of flags.
Introduce a couple of new flags for the permissions (Non-eXecutable,
Read-Only) and also provides definition that combine the memor
Currently MAIRVAL is defined in term of MAIR0VAL and MAIR1VAL which are

This is based on the Linux ARMv8 naming scheme (see arch/arm64/mm/proc.S). Each
type will contain "NORMAL" or "DEVICE" to make clear whether each attribute
targets device or normal memory.

Hi all,
This patch series contains clean-up for the ARM memory subsystem in preparation
of reworking the page tables handling.
For all changes, see in each patch.
Cheers,

The parameter 'ai' is used either for attribute index or for
permissions. Follow-up patch will rework that parameters to carry more
information. So rename the parameter to 'flags'.
