In [0], we added support for storing struct task_struct * objects as
kptrs. This patch set extends this effort to also include storing struct
cgroup * object as kptrs.
As with tasks, there are many possible use cases for storing cgroups in

statistics such as PSI averages, or tracking which tasks are migrating
to and from the cgroup.

struct cgroup * objects have a variably sized struct cgroup *ancestors[]
field which stores pointers to their ancestor cgroups. If using a cgroup
as a kptr, it can be useful to access these ancestors, but doing so
requires variable offset accesses for PTR_TO_BTF_ID, which is currently
unsupported.
This is a very useful field to access for cgroup kptrs, as programs may
wish to walk their ancestor cgroups when determining e.g. their
proportional cpu.weight. So as to enable this functionality with cgroup
kptrs before var_off is supported for PTR_TO_BTF_ID, this patch adds a
bpf_cgroup_ancestor() kfunc which accesses the cgroup node on behalf of
the caller, and acquires a reference on it. Once var_off is supported
for PTR_TO_BTF_ID, and fields inside a struct can be marked as trusted
so they retain the PTR_TRUSTED modifier when walked, this can be
removed.

Now that tasks can be used as kfuncs, and the PTR_TRUSTED flag is
available for us to easily add basic acquire / get / release kfuncs, we
can do the same for cgroups. This patch set adds the following kfuncs
which enable using cgroups as kptrs:
struct cgroup *bpf_cgroup_acquire(struct cgroup *cgrp);
struct cgroup *bpf_cgroup_kptr_get(struct cgroup **cgrpp);
void bpf_cgroup_release(struct cgroup *cgrp);
A follow-on patch will add a selftest suite which validates these
kfuncs.

We face some regressions on a few IXP42x systems when
accessing flash, the following unrelated error prints
appear from the PCI driver:
ixp4xx-pci c0000000.pci: PCI: abort_handler addr = 0xff9ffb5f,
isr = 0x0, status = 0x22a0
ixp4xx-pci c0000000.pci: imprecise abort
(...)
It turns out that while bit 7 is masked "reserved" it is
not unused, so masking it off as zero is dangerous, and
breaks flash access on some systems such as the NSLU2.
Be more careful and avoid masking off any of the reserved
bits 7, 8, 9 or 30. Only keep masking EXP_WORD (bit 2)
on IXP43x which is necessary in some setups.

After commit cbfecb927f ("fs: record I_DIRTY_TIME even if inode

I_DIRTY_TIME set to b_dirty_time list. In case of freeing inode with
I_DIRTY_TIME set this can happen after deletion of inode from i_io_list
at evict. Stack trace is following.
evict
fat_evict_inode
fat_truncate_blocks
fat_flush_inodes
writeback_inode
sync_inode_metadata(inode, sync=0)
writeback_single_inode(inode, wbc) <- wbc->sync_mode == WB_SYNC_NONE
This will lead to use after free in flusher thread.

When the amd_pstate driver is built-in users still need a method to be

There is some performance degradation on a number of ASICs in the
passive mode. This performance issue was originally discovered in
shared memory systems but it has been proven that certain workloads
on MSR systems also suffer performance issues.
Set the amd-pstate driver as disabled by default to temporarily
mitigate the performance problem.
1) with `amd_pstate=disable`, pstate driver will be disabled to load at
kernel booting.
2) with `amd_pstate=passive`, pstate driver will be enabled and loaded
as non-autonomous working mode supported in the low-level power
management firmware.
3) If neither parameter is specified, the driver will be disabled by

MSR_AMD_PERF_CTL is guaranteed to be 0 on a cold boot. However, on a
kexec boot, for instance, it may have a non-zero value (if the cpu was
in a non-P0 Pstate). In such cases, the cores with non-P0 Pstates at
boot will never be pushed to P0, let alone boost frequencies.
Kexec is a common workflow for reboot on Linux and this creates a
regression in performance. Fix it by explicitly setting the
MSR_AMD_PERF_CTL to 0 during amd_pstate driver init.

If there's a disconnection while operating in eSS, there may be a delay
in VBUS drop response from the connector. In that case, the internal
link state may drop to operate in usb2 speed while the controller thinks
the VBUS is still high. The driver must make sure to disable
GUSB2PHYCFG.SUSPHY when sending endpoint command while in usb2 speed.
The End Transfer command may be called, and only that command needs to
go through at this point. Let's keep it simple and unconditionally
disable GUSB2PHYCFG.SUSPHY whenever we issue the command.
This scenario is not seen in real hardware. In a rare case, our
prototype type-c controller/interface may have a slow response
triggerring this issue.

If PTP synchronisation is done every second, then sporadic the interval
is higher than one second:

^^^^^^^ Should be 698.582!
This problem is caused by rotten packets, which are received after
polling but before interrupts are enabled again. This can be fixed by
checking for pending work and rescheduling if necessary after interrupts
has been enabled again.

Colin Foster says:
====================
cleanup ocelot_stats exposure
The ocelot_stats structures became redundant across all users. Replace
this redundancy with a static const struct. After doing this, several
definitions inside include/soc/mscc/ocelot.h no longer needed to be
shared. Patch 2 removes them.
Checkpatch throws an error for a complicated macro not in parentheses. I
understand the reason for OCELOT_COMMON_STATS was to allow expansion, but
interestingly this patch set is essentially reverting the ability for
expansion. I'm keeping the macro in this set, but am open to remove it,
since it doesn't _actually_ provide any immediate benefits anymore.

Ocelot uses regmap_bulk_read() operations to efficiently read stats
registers. Currently the implementation relies on the stats layout to be
ordered to be most efficient.

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.

Here are the steps to install the latest grep:
