At the moment we create a small window only for 32bit devices, the window
maps 0..2GB of the PCI space only. For other devices we either use
a sketchy bypass or hardware bypass but the former can only work if
the amount of RAM is no bigger than the device's DMA mask and the latter
requires devices
We allocate only the first level of multilevel TCE tables for KVM
already (alloc_userspace_copy==true), and the rest is allocated on demand.
This is not enabled though for baremetal.
This removes the KVM limitation (implicit, via the alloc_userspace_copy
parameter) and always allocates just the fi
This is an attempt to allow DMA mask 40 or similar which are not large
enough to use either a PHB3 bypass mode or a sketchy bypass.

commit 8a583c0a8d316d8ea52ea78491174ab1a3e9ef9d upstream.
binutils >= 2.26 now warns about misuse of register expressions in
assembler operands that are actually literals, for example:

Hi Greg,
Please queue up these powerpc patches for 4.9 if you have no objections.
There's one build fix for newer toolchains, and the rest are spectre related.
cheers

How much symbol versioning will be required for this change?

When we want to support more sample rate, for example 12kHz/24kHz
we need update the process_option table, if we want to support more
sample rate next time, the table need to be updated again. which
is not flexible.
We got a function fsl_asrc_sel_proc to replace the table, which can
give the pre-p

Hi Rob and Mark,
I am upgrading the kernel on a Freescale P2040 based system and have
struck an issue with LIODNs not being updated by uboot for an FMAN
ethernet port.
My system has an old uboot running which fails in its attempt to update
the fman rx port node with the required LIODN entry. This
