This just adds the zl2006 voltage regulators / power monitors and the
onboard I2C eeproms. The ICS9FG108 clock chip doesn't seem to have a

the SPD eeproms are tagged as such.

Hi all,
the dma_get_required_mask dma API implementation has always been a little
odd, in that we by default don't wire it up struct dma_map_ops, but
instead hard code a default implementation. powerpc and ia64 override
this default and either call a method or otherwise duplicate the default.
This is somewhat modelled after the powerpc version, and differs from
the legacy fallback in use fls64 instead of pointlessly splitting up the
address into low and high dwords and in that it takes (__)phys_to_dma
into account.

This save some duplication for ia64, and makes the interface more
general. In the long run we want each dma_map_ops instance to fill this
out, but this will take a little more prep work.

This way an architecture with less than 4G of RAM can support dma_mask

Currently we limit the max addressable memory to 128TB. This patch increase the
limit to 2PB. We can have devices like nvdimm which adds memory above 512TB
limit.
We still don't support regular system ram above 512TB. One of the challenge with
that is the percpu allocator, that allocates per node
We will be adding get_kernel_context later. Update function name to indicate
this handle context allocation user space address.

asm-generic/hugetlb.h proposes generic implementations of hugetlb
related functions: use __HAVE_ARCH_HUGE* defines in order to make arch
specific implementations of hugetlb functions consistent with pgtable.h

Hi Andrew,
As suggested by people who reviewed/acked this series, please consider
including this series into -mm tree.
In order to reduce copy/paste of functions across architectures and then
make riscv hugetlb port (and future ports) simpler and smaller, this
