a48777fdda x86/vsmp: Remove dependency on pv_irq_ops
vSMP dependency on pv_irq_ops has been removed some years ago, but the code
still deals with pv_irq_ops.

In short, "cap & ctl & (1 << 4)" is always returning 0, so all
PARAVIRT/PARAVIRT_XXL code related to that can be removed.

However, the rest of the code depends on CONFIG_PCI, so fix it accordingly.

Rename set_vsmp_pv_ops to set_vsmp_ctl as the original name does not make
sense anymore.

b082f2dd80 x86/ldt: Remove unused variable in map_ldt_struct()
Splitting out the sanity check in map_ldt_struct() moved page table syncing
into a separate function, which made the pgd variable unused. Remove it.

a0e6e0831c x86/ldt: Unmap PTEs for the slot before freeing LDT pages
modify_ldt(2) leaves the old LDT mapped after switching over to the new
one. The old LDT gets freed and the pages can be re-used.

Leaving the mapping in place can have security implications. The mapping is
present in the userspace page tables and Meltdown-like attacks can read
these freed and possibly reused pages.

It's relatively simple to fix: unmap the old LDT and flush TLB before
freeing the old LDT memory.

This further allows to avoid flushing the TLB in map_ldt_struct() as the
slot is unmapped and flushed by unmap_ldt_struct() or has never been mapped
at all.

d52888aa27 x86/mm: Move LDT remap out of KASLR region on 5-level paging
On 5-level paging the LDT remap area is placed in the middle of the KASLR
randomization region and it can overlap with the direct mapping, the
vmalloc or the vmap area.

The LDT mapping is per mm, so it cannot be moved into the P4D page table
next to the CPU_ENTRY_AREA without complicating PGD table allocation for
5-level paging.

The 4 PGD slot gap just before the direct mapping is reserved for
hypervisors, so it cannot be used.

Move the direct mapping one slot deeper and use the resulting gap for the
LDT remap area. The resulting layout is the same for 4 and 5 level paging.

042cb56478 net: phy: Allow BCM54616S PHY to setup internal TX/RX clock delay
This patch allows users to enable/disable internal TX and/or RX clock
delay for BCM54616S PHYs so as to satisfy RGMII timing specifications.

On a particular platform, whether TX and/or RX clock delay is required
depends on how PHY connected to the MAC IP. This requirement can be
specified through "phy-mode" property in the platform device tree.

The patch is inspired by commit 733336262b ("net: phy: Allow BCM5481x
PHYs to setup internal TX/RX clock delay").

a8d6219536 ISDN: eicon: Remove driver
I started looking at the history of this driver, and last time the
maintainer was active on the mailing list was when discussing how to
remove it. This was in 2012:

https://lore.kernel.org/lkml/4F4DE175.30002@melware.de/

It looks to me like this has in practice been an orphan for quite a while.
It's throwing warnings about stack size in a function that is in dire
need of refactoring, and it's probably a case of "it's time to call it".

  syscall table details, what to copy, how many bytes, pid, arg filters from the
  userspace via eBPF maps by the 'perf trace' tool that continues to use all its
  argument beautifiers, just taking advantage of the extra pointer contents.

JVMTI: (Gustavo Romero)

- Fix undefined symbol scnprintf in libperf-jvmti.so

perf top: (Jin Yao)

- Display the LBR stats in callchain entries

e8a308e5f4 acpi/nfit, x86/mce: Validate a MCE's address before using it
The NFIT machine check handler uses the physical address from the mce
structure, and compares it against information in the ACPI NFIT table
to determine whether that location lies on an NVDIMM. The mce->addr
field however may not always be valid, and this is indicated by the
MCI_STATUS_ADDRV bit in the status field.

Export mce_usable_address() which already performs validation for the
address, and use it in the NFIT handler.

5d96c9342c acpi/nfit, x86/mce: Handle only uncorrectable machine checks
The MCE handler for nfit devices is called for memory errors on a
Non-Volatile DIMM and adds the error location to a 'badblocks' list.
This list is used by the various NVDIMM drivers to avoid consuming known
poison locations during IO.

The MCE handler gets called for both corrected and uncorrectable errors.
Until now, both kinds of errors have been added to the badblocks list.
However, corrected memory errors indicate that the problem has already
been fixed by hardware, and the resulting interrupt is merely a
notification to Linux.

As far as future accesses to that location are concerned, it is
perfectly fine to use, and thus doesn't need to be included in the above
badblocks list.

Add a check in the nfit MCE handler to filter out corrected mce events,
and only process uncorrectable errors.

e401fa25cf qtnfmac: add support for Topaz chipsets
This patch adds support for QSR1000/QSR2000 family of chipsets
to qtnfmac_pcie platform driver.

QSR1000/QSR2000 (aka Topaz) is a family of 80MHz, 11ac Wave2,
4x4/2x4/2x2 chips, including single and dual band devices.
Depending on specific chip model and firmware in use, either
STA or both STA and AP modes are supported.

Patch adds Topaz support to qtnfmac_pcie driver. Proper platform
bus will be selected on probing based on chip ID.

29ec3394f0 brcmfmac: Fix ccode from EFI nvram when necessary
In some cases the EFI-var stored nvram contains "ccode=ALL" or "ccode=XV"
to specify "worldwide" compatible settings, but these 2 ccode-s do not work
properly.

I've tested the different known "worldwide" ccode-s used in various nvram
sources with the latest firmwares from linux-firmware for various brcmfmac
models, here is a simplified (*) table with what each setting results in:

ALL: 12-14 disab, U-NII-1, U-NII-2 no-IR/radar, U-NII-3
XV:  12-14 no-IR, disables all 5G channels
XY:  12-13 enab, 14 disab, U-NII-1 enab, U-NII-2 no-IR/radar, U-NII-3 disab
X2:  12-13 no-IR, 14 dis, U-NII-1 no-IR, U-NII-2 no-IR/radar, U-NII-3 no-IR

Where 12,13,14 are 2.4G channels 12-14 and U-NII-1/2/3 are the 3 different
5G channel groups. no-IR is no-Initiate-Radiation, we will never send on
these channels without first having received valid wifi traffic there.

This immediately shows that both ALL and XV are not as worldwide as we want
them to be. ALL causes channels 12 and 13 to not be available and XV causes
all 5GHz channels to not be available. Also ALL unconditionally enables the
U-NII-1 and U-NII-3 5G groups, while we really should be using no-IR for
these.

This commit replace XV and ALL with X2, which allows usage of chan 12-13
and 5G channels, but only after receiving valid wifi traffic there first.

Note that this configure the firmware's channel limits, the kernels own
regulatory restrictions based on e.g. regulatory info received from the
access-point, will be applied on top of this.

This fixes channels 12+13 not working on the Asus T200TA and the Lenovo
Mixx 2 8 and 5G channels not working on the Asus T100HA.

This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a
Lenovo Mixx 2 8.

*) There are some exceptions to this table:
1) On really old firmware e.g. linux-firmware's 2011 brcmfmac4330-sdio.bin
   ALL really means all, unconditionally enabling everything
2) The exact meaning might be influenced by setting the regrev nvram var.
   Specifically using ccode=XV + regrev=1 on brcmfmac43241b4 leads to:
   12-14 no-ir, U-NII-1 no-ir, U-NII-2 no-ir/radar, U-NII-3 no-ir
   But only on the brcmfmac43241b4 and not on e.g. the brcmfmac43340

ce2e6db554 brcmfmac: Add support for getting nvram contents from EFI variables
Various X86 laptops with a SDIO attached brcmfmac wifi chip, store the
nvram contents in a special EFI variable. This commit adds support for
getting nvram directly from this EFI variable, without the user needing
to manually copy it.

This makes Wifi / Bluetooth work out of the box on these devices instead of
requiring manual setup.

This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a
Lenovo Mixx 2 8.

bd1e82bb42 brcmfmac: Set board_type from DMI on x86 based machines
For x86 based machines, set the board_type used for nvram file selection
based on the DMI sys-vendor and product-name strings.

Since on some models these strings are too generic, this commit also adds
a quirk table overriding the strings for models listed in that table.

The board_type setting is used to load the board-specific nvram file with
a board-specific name so that we can ship files for each supported board
in linux-firmware.

eae8e50669 brcmfmac: Add support for first trying to get a board specific nvram file
The nvram files which some brcmfmac chips need are board-specific. To be
able to distribute these as part of linux-firmware, so that devices with
such a wifi chip will work OOTB, multiple (one per board) versions must
co-exist under /lib/firmware.

This commit adds support for callers of the brcmfmac/firmware.c code to
pass in a board_type parameter through the request structure.

If that parameter is set then the code will first try to load
chipmodel.board_type.txt before falling back to the old chipmodel.txt name.
