i915 does not want to see value entries. Switch it to use
find_lock_page() instead, and remove the export of find_lock_entry().
Move find_lock_entry() and find_get_entry() to mm/internal.h to discourage
any future use.Signed-off-by: Matthew Wilcox (Oracle)

The 'struct resource' in 'struct dev_pagemap' is only used for holding
resource span information. The other fields, 'name', 'flags', 'desc',
'parent', 'sibling', and 'child' are all unused wasted space.This is in preparation for introducing a multi-range extension of
devm_memremap_pages().The bulk of this change is unwinding all the places internal to libnvdimm
that used 'struct resource' unnecessarily, and replacing instances of
'struct dev_pagemap'.res with 'struct dev_pagemap'.range.P2PDMA had a minor usage of the resource flags field, but only to report
failures with "%pR". That is replaced with an open coded print of the
range.[dan.carpenter@oracle.com: mm/hmm/test: use after free in dmirror_allocate_chunk()]

As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()

A recent attempt to fix a ref count leak in
amdgpu_display_crtc_set_config() turned out to be doing too much and
"fixed" an intended decrease as if it were a leak. Undo that part to
restore the proper balance. This is the very nature of this function
to increase or decrease the power reference count depending on the
situation.Consequences of this bug is that the power reference would
eventually get down to 0 while the display was still in use,
resulting in that display switching off unexpectedly.Signed-off-by: Jean Delvare
