Pull power management updates from Rafael Wysocki:
"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.
There are also other cpufreq updates (in the core, intel_pstate, ARM
drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.

Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification

- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.

Merge tag 'slab-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- Separate struct slab from struct page - an offshot of the page folio
work.
Struct page fields used by slab allocators are moved from struct page
to a new struct slab, that uses the same physical storage. Similar to
struct folio, it always is a head page. This brings better type
safety, separation of large kmalloc allocations from true slabs, and
cleanup of related objcg code.
- A SLAB_MERGE_DEFAULT config optimization.

Pull random number generator updates from Jason Donenfeld:
"These a bit more numerous than usual for the RNG, due to folks
resubmitting patches that had been pending prior and generally renewed
interest.
There are a few categories of patches in here:
1) Dominik Brodowski and I traded a series back and forth for a some
weeks that fixed numerous issues related to seeds being provided
at extremely early boot by the firmware, before other parts of the
kernel or of the RNG have been initialized, both fixing some
crashes and addressing correctness around early boot randomness.
One of these is marked for stable.
2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
extractor, and made the construction a bit safer and more
standard. This was sort of a long overdue low hanging fruit, as we
were supposed to have phased out SHA-1 usage quite some time ago
(even if all we needed here was non-invertibility). Along the way
it also made extraction 131% faster. This required a bit of
Kconfig and symbol plumbing to make things work well with the
crypto libraries, which is one of the reasons why I'm sending you
this pull early in the cycle.
3) I got rid of a truly superfluous call to RDRAND in the hot path,
which resulted in a whopping 370% increase in performance.
4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
the full series of which wasn't ready yet, but the first two
preparatory cleanups were good on their own. One of them touches
files in kernel/irq/, which is the other reason why I'm sending
you this pull early in the cycle.
5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
Mark Brown, Dominik Brodowski, and myself"

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top
box based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908.

== Problem ==
Nathan Chancellor reported an oops when aceessing the
'sgx_total_bytes' sysfs file:
https://lore.kernel.org/all/YbzhBrimHGGpddDM@archlinux-ax161/
The sysfs output code accesses the sgx_numa_nodes[] array
unconditionally. However, this array is allocated during SGX
initialization, which only occurs on systems where SGX is
supported.
If the sysfs file is accessed on systems without SGX support,
sgx_numa_nodes[] is NULL and an oops occurs.
== Solution ==
To fix this, hide the entire nodeX/x86/ attribute group on
systems without SGX support using the ->is_visible attribute
group callback.
Unfortunately, SGX is initialized via a device_initcall() which
occurs _after_ the ->is_visible() callback. Instead of moving
SGX initialization earlier, call sysfs_update_group() during
SGX initialization to update the group visiblility.
This update requires moving the SGX sysfs code earlier in
sgx/main.c. There are no code changes other than the addition of
arch_update_sysfs_visibility() and a minor whitespace fixup to
arch_node_attr_is_visible() which checkpatch caught.

The PCI Write Barrier instruction ignores the registers encoded in it.
There is thus no need to explicitly set the register to zero or to
associate it with a variable at all. In the resulting binary this removes
an unnecessary lghi and it makes the code simpler.

In preparation for using blake2s in the RNG, we change the way that it
is wired-in to the build system. Instead of using ifdefs to select the
right symbol, we use weak symbols. And because ARM doesn't need the
generic implementation, we make the generic one default only if an arch
library doesn't need it already, and then have arch libraries that do
need it opt-in. So that the arch libraries can remain tristate rather
than bool, we then split the shash part from the glue code.

page->freelist is for the use of slab. Using page->index is the same
set of bits as page->freelist, and by using an integer instead of a
pointer, we can avoid casts.

The following error is reported when running "./test_progs -t for_each"
under arm64:
bpf_jit: multi-func JIT bug 58 != 56
[...]
JIT doesn't support bpf-to-bpf calls
The root cause is the size of BPF_PSEUDO_FUNC instruction increases
from 2 to 3 after the address of called bpf-function is settled and
there are two bpf-to-bpf calls in test_pkt_access. The generated
instructions are shown below:
0x48: 21 00 C0 D2 movz x1, #0x1, lsl #32
0x4c: 21 00 80 F2 movk x1, #0x1
0x48: E1 3F C0 92 movn x1, #0x1ff, lsl #32
0x4c: 41 FE A2 F2 movk x1, #0x17f2, lsl #16
0x50: 81 70 9F F2 movk x1, #0xfb84
Fixing it by using emit_addr_mov_i64() for BPF_PSEUDO_FUNC, so
the size of jited image will not change.

Nomap regions are treated as "reserved". When region boundaries are not
page aligned, we usually increase the "reserved" regions rather than
decrease them. So, we should use memblock_region_reserved_base_pfn()/
memblock_region_reserved_end_pfn() instead of memblock_region_memory_
base_pfn()/memblock_region_memory_base_pfn() to calculate boundaries.

As started by commit 05a5f51ca5 ("Documentation: Replace lkml.org links
with lore"), an effort was made to replace lkml.org links with lore to
better use a single source that's more likely to stay available long-term.
However, it seems these links don't offer much value here, so just
remove them entirely.

The current EPB "normal" is defined as 6 and set whenever power-up EPB
value is 0. This setting resulted in the desired out of box power and
performance for several CPU generations. But this value is not suitable
for AlderLake mobile CPUs, as this resulted in higher uncore power.
Since EPB is model specific, this is not unreasonable to have different
behavior.
Allow a capability where "normal" EPB can be redefined. For AlderLake
mobile CPUs this desired normal value is 7.
