Hi,
The following three patches fix minor issues in rpm_suspend() and rpm_resume().
They are on top of the current linux-next branch of the linux-pm.git tree, but
they should apply to the mainline too.
[1/3] - Fix rpm_resume() return value for power.no_callbacks set and active
parent.
The power.deferred_resume can only be set if the runtime PM status
of device is RPM_SUSPENDING and it should be cleared after its
status has been changed, regardless of whether or not the runtime
suspend has been successful. However, it only is cleared on suspend
failure, while it may remain set
If __dev_pm_qos_read_value(dev) returns a negative value,
rpm_suspend() should return -EPERM for dev even if its
power.no_callbacks flag is set. For this to happen, the device's
power.no_callbacks flag has to be checked after the PM QoS check,
so modify the code accordingly.

FYI, here is a different back trace on that commit.
It seems commit 2098e95ce9bb039ff2e7bf836df358d18a176139 (regulator: twl:
adapt twl-regulator driver to dt) accidentally deleted VINTANA1. Also
the same commit defines VINTANA2 twice with TWL4030_ADJUSTABLE_LDO and
TWL4030_FIXED_LDO. This patch changes the fixed one to be VINTANA1.

Depending on the platform, init_memory_mapping() may be called multiple
times. Move it out to setup_arch() to avoid writing to cr4 on every call.

Current logic finds enough space for direct mapping page tables from 0
to end. Instead, we only need to find enough space to cover mr[0].start
to mr[nr_range].end -- the range that is actually being mapped by
init_memory_mapping()
This patch also reportedly fixes suspend/resume issue reported in:
Currently direct mappings are created for [ 0 to max_low_pfnPAGE_SHIFT )
and [ 4GB to max_pfnPAGE_SHIFT ), which may include regions that are not
backed by actual DRAM. This is fine for holes under 4GB which are covered
by fixed and variable range MTRRs to be UC. However, we run into trouble

Currently kernel direct mappings are created for all pfns between
[ 0 to max_low_pfn ) and [ 4GB to max_pfn ). When we introduce memory
holes, we end up mapping memory ranges that are not backed by physical
DRAM. This is fine for lower memory addresses which can be marked as UC
by fixed/variable
Update code that previously assumed pfns [ 0 - max_low_pfn_mapped ) and
[ 4GB - max_pfn_mapped ) were always direct mapped, to now look up
pfn_mapped ranges instead.

Hi,
There are several patches on the subject:

c55ad8e56b983f03589b38b4504b5d1f41161ff8
Add lock to prevent a race with a file closing and also remove
useless and ugly sscanf code. The extra code was never needed
and the case it supposedly protected against is in fact handled
correctly by sock_from_file as pointed out by Al Viro.

A socket fd passed in a SCM_RIGHTS datagram was not getting
updated with the new tasks cgrp prioidx. This leaves IO on
the socket tagged with the old tasks priority.
To fix this add a check in the scm recvmsg path to update the
sock cgrp prioidx with the new tasks value.
Thanks to Al Viro for
A race exists where creating cgroups and also updating the priomap
may result in losing a priomap update. This is because priomap
writers are not protected by rtnl_lock.
Move priority writer into rtnl_lock()/rtnl_unlock().
