When a divider clock has CLK_DIVIDER_READ_ONLY set, it means that the
register shall be left un-touched, but it does not mean the clock
should stop rate propagation if CLK_SET_RATE_PARENT is set
This is properly handled in qcom clk-regmap-divider but it was not in
the generic divider

A read-only divider may also have CLK_SET_RATE_PARENT flag set, in which
case it should propagate the requested rate to its parent, taking the

Then I'm really confused. It says "ro" above, which means _PAGE_RW is

Not broken - simply no one needed it until now. I'm looking
While the implementation of the "slices" address space allows
a significant amount of high slices, it limits the number of
low slices to 16 due to the use of a single u64 low_slices element
in struct slice_mask.
In order to override this limitation, this patch switches the
handling of low_slices
When an app has some regular pages allocated (e.g. see below) and tries
to mmap() a huge page at a hint address covered by the same PMD entry,
the kernel accepts the hint allthough the 8xx cannot handle different
page sizes in the same PMD entry.
1000-10001000 r-xp 00:0f 2597
On the 8xx, we can have as many slices as PMD entries.
This means we could have 1024 slices in 4k size pages mode
and 64 slices in 16k size pages.
However, due to a stack overflow in slice_get_unmapped_area(),
we limit to 512 slices.

Hi Andy,

This patch set improves stability and accuracy of the system clock
when synchronized to precise time sources like the new PTP KVM clock or
NTP/PTP with hardware timestamping. The biggest difference is expected
on mostly idle systems

Hi,
we have two more fixes for 4.15, aimed for stable. The leak fix is
obvious, the second patch fixes a bug revealed by the refcount API, when
it behaves differently than previous atomic_t and reports refs going
from 0 to 1 in one case.
No merge conflicts. Please pull, thanks.
