x86/speculation/l1tf: Fix overflow in l1tf_pfn_limit() on 32bit
On 32bit PAE kernels on 64bit hardware with enough physical bits,
l1tf_pfn_limit() will overflow unsigned long. This in turn affects
max_swapfile_size() and can lead to swapon returning -EINVAL. This has been
observed in a 32bit guest with 42 bits physical address size, where
max_swapfile_size() overflows exactly to 1 << 32, thus zero, and produces
the following warning to dmesg:
[ 6.396845] Truncating oversized swap area, only using 0k out of 2047996k
Fix this by using unsigned long long instead.

x86/speculation/l1tf: Exempt zeroed PTEs from inversion
It turns out that we should *not* invert all not-present mappings,
because the all zeroes case is obviously special.
clear_page() does not undergo the XOR logic to invert the address bits,
i.e. PTE, PMD and PUD entries that have not been individually written
will have val=0 and so will trigger __pte_needs_invert(). As a result,
{pte,pmd,pud}_pfn() will return the wrong PFN value, i.e. all ones
(adjusted by the max PFN mask) instead of zero. A zeroed entry is ok
because the page at physical address 0 is reserved early in boot
specifically to mitigate L1TF, so explicitly exempt them from the
inversion when reading the PFN.
Manifested as an unexpected mprotect(..., PROT_NONE) failure when called
on a VMA that has VM_PFNMAP and was mmap'd to as something other than
PROT_NONE but never used. mprotect() sends the PROT_NONE request down
prot_none_walk(), which walks the PTEs to check the PFNs.
prot_none_pte_entry() gets the bogus PFN from pte_pfn() and returns
-EACCES because it thinks mprotect() is trying to adjust a high MMIO
address.
[ This is a very modified version of Sean's original patch, but all
credit goes to Sean for doing this and also pointing out that
sometimes the __pte_needs_invert() function only gets the protection
bits, not the full eventual pte. But zero remains special even in
just protection bits, so that's ok. - Linus ]

cycle ratios can be adjusted while taking into account things like clk

support for this, but I expect there will be more to come in the

Outside of the core, we have the usual pile of clk driver updates and
additions. The Amlogic meson driver got the most lines in the diffstat
this time around because it added support for a whole bunch of
hardware and duty cycle configuration. After that the Rockchip PX30,
Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the
diff. We're left with the collection of non-critical fixes after that.

Merge tag 'gpio-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.19 kernel cycle.
I don't know if anything in particular stands out. Maybe the Aspeed
coprocessor thing from Benji: Aspeed is doing baseboard management
chips (BMC's) for servers etc.
These Aspeed's are ARM processors that exist inside (I guess) Intel
servers, and they are moving forward to using mainline Linux in those.
This is one of the pieces of the puzzle to achive that. They are doing
OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/
Summary:
Core changes:
- Add a new API for explicitly naming GPIO consumers, when needed.
- Don't let userspace set values on input lines. While we do not
think anyone would do this crazy thing we better plug the hole
before someone uses it and think it's a nifty feature.
- Avoid calling chip->request() for unused GPIOs.
New drivers/subdrivers:
- The Mediatek MT7621 is supported which is a big win for OpenWRT and
similar router distributions using this chip, as it seems every
major router manufacturer on the planet has made products using
this chip: https://wikidevi.com/wiki/MediaTek_MT7621
- The Tegra 194 is now supported.
- The IT87 driver now supports IT8786E and IT8718F super-IO chips.
- Add support for Rockchip RK3328 in the syscon GPIO driver.
Driver changes:
- Handle the get/set_multiple() properly on MMIO chips with inverted
direction registers. We didn't have this problem until a new chip
appear that has get/set registers AND inverted direction bits, OK
now we handle it.
- A patch series making more error codes percolate upward properly
for different errors on gpiochip_lock_as_irq().
- Get/set multiple for the OMAP driver, accelerating these multiple
line operations if possible.
- A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
lines need to be grabbed by a co-processor for doing automated
tasks, sometimes they are available as GPIO lines. By adding an
explicit API in this driver we make it possible for the two line
consumers to coexist. (This work was made available on the
ib-aspeed branch, which may be appearing in other pull requests.)
- Implemented .get_direction() and open drain in the SCH311x driver.
- Continuing cleanup of included headers in GPIO drivers"

ALSA: update dell-wmi mic-mute registration to new world order
Commit 4e3fbe9849e8 ("ALSA: hda - Allow multiple ADCs for mic mute LED
controls") changed the return value of the snd_hda_gen_add_micmute_led()
without actually updating the callers.
Admittedly, almost no callers actually cared about the return value.
But one call site very much did: the Dell wmi code. It would see the
registration return zero, which _used_ to mean "failed" but now means
"success", and clear the dell_micmute_led_set_func pointer.
End result: the successful registration would end up calling the Dell
code that thought it had all failed, and call through a NULL pointer.
To make matters worse, it ends up being a tail-call, and with the
retpoline sequence you don't even see the caller (dell_micmute_update())
in the stack trace, so the error ended up way less obvious than it
should have been.

PCI/AER: Don't clear AER bits if error handling is Firmware-First
If the platform requests Firmware-First error handling, firmware is
responsible for reading and clearing AER status bits. If OSPM also clears
them, we may miss errors. See ACPI v6.2, sec 18.3.2.5 and 18.4.
This race is mostly of theoretical significance, as it is not easy to
reasonably demonstrate it in testing.

Like the NFP4000 and NFP6000, the NFP5000 as an erratum where reading/

generate PCIe completion timeouts.
Limit the NFP5000's PF's config space size to 0x600 bytes as is already

The NFP5000's VF is 0x6003 (PCI_DEVICE_ID_NETRONOME_NFP6000_VF), the same

Pull arm64 updates from Will Deacon:
"A bunch of good stuff in here. Worth noting is that we've pulled in
the x86/mm branch from -tip so that we can make use of the core
ioremap changes which allow us to put down huge mappings in the
vmalloc area without screwing up the TLB. Much of the positive
diffstat is because of the rseq selftest for arm64.
Summary:
- Wire up support for qspinlock, replacing our trusty ticket lock
code
- Add an IPI to flush_icache_range() to ensure that stale
instructions fetched into the pipeline are discarded along with the
I-cache lines
- Support for the GCC "stackleak" plugin
- Support for restartable sequences, plus an arm64 port for the
selftest
- Kexec/kdump support on systems booting with ACPI
- Rewrite of our syscall entry code in C, which allows us to zero the
GPRs on entry from userspace
- Support for chained PMU counters, allowing 64-bit event counters to
be constructed on current CPUs
- Ensure scheduler topology information is kept up-to-date with CPU
hotplug events
- Re-enable support for huge vmalloc/IO mappings now that the core
code has the correct hooks to use break-before-make sequences
- Miscellaneous, non-critical fixes and cleanups"

PCI/MSI: Set IRQCHIP_ONESHOT_SAFE for PCI-MSI irqchips
If flag IRQCHIP_ONESHOT_SAFE isn't set for an irqchip and we have a
threaded interrupt with no primary handler, flag IRQF_ONESHOT needs to be
set for the interrupt, causing some overhead in the threaded interrupt
handler. For more detailed explanation also check following comment in
__setup_irq():
The interrupt was requested with handler = NULL, so we use the default
primary handler for it. But it does not have the oneshot flag set. In
combination with level interrupts this is deadly, because the default
primary handler just wakes the thread, then the irq lines is reenabled,
but the device still has the level irq asserted. Rinse and repeat....
While this works for edge type interrupts, we play it safe and reject
unconditionally because we can't say for sure which type this interrupt
really has. The type flags are unreliable as the underlying chip
implementation can override them.
Another comment in __setup_irq() gives a hint already that this
overhead can be avoided for PCI-MSI:
Some irq chips like MSI based interrupts are per se one shot safe. Check
the chip flags, so we can avoid the unmask dance at the end of the
threaded handler for those.
Following this let's mark all PCI-MSI irqchips as oneshot-safe.

x86/init: fix build with CONFIG_SWAP=n
The introduction of generic_max_swapfile_size and arch-specific versions has
broken linking on x86 with CONFIG_SWAP=n due to undefined reference to
'generic_max_swapfile_size'. Fix it by compiling the x86-specific
max_swapfile_size() only with CONFIG_SWAP=y.

Merge tag 'regmap-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"Several small new features for regmap this time around:
- Support for SCCB, an I2C variant used on some media cards. This has
also pulled in an I2C commit from Peter Rosin as a dependency.
- Addition of an API for reading repeatedly from registers where the
address doesn't automatically increment like some ADC outputs or
GPIO status registers.
- Support for bulk I/O on Slimbus"
