What are the disks hanging off ?
Apply new interface to map external powerpc cpus across multiple
nodes to a range of kernel cpu values. Mapping is intended to
prevent confusion within the kernel about the cpu+node mapping, and
the changes in configuration that may happen due to powerpc LPAR
migration or other associativity
Missing linux/mm.h
Will fix it in the coming patch.

The AFU Descriptor Template in the PCI config space has a Name Space
field which is a 24 Byte ASCII character string of descriptive name
space for the AFU. The OCXL driver read the string four characters at
a time with pci_read_config_dword().
This optimization is valid on a little-endian system

This patch enables CONFIG_VMAP_STACK. For that, a few changes are
done in head_8xx.S to re-activation DATA MMU Translation before
accessing to the stack.
Due to the growing of exception prolog, a few rearrangement is also
done in a few exception handlers.

To support CONFIG_VMAP_STACK, the kernel must be able to activate
Data MMU Translation for accessing the stack. Before doing that
it must save SRR0, SRR1 and DAR in order to not loose them in
case there is a Data TLB Miss once the translation is reactivated.
This patch defines fields in the
In preparation of handling CONFIG_VMAP_STACK, we need DTLB miss handler
to use different scratch registers than other exception handlers in
