Two users have reported [1] that they have an "extremely unlikely" system
with more than MAX_PA/2 memory and L1TF mitigation is not effective.

Make the warning more helpful by suggesting the proper mem=X kernel boot
parameter to make it effective and a link to the L1TF document to help
decide if the mitigation is worth the unusable RAM.

Two users have reported [1] that they have an "extremely unlikely" system
with more than MAX_PA/2 memory and L1TF mitigation is not effective. In
fact it's a CPU with 36bits phys limit (64GB) and 32GB memory, but due to
holes in the e820 map, the main region is almost 500MB over the 32GB limit:

[    0.000000] BIOS-e820: [mem 0x0000000100000000-0x000000081effffff] usable

Suggestions to use 'mem=32G' to enable the L1TF mitigation while losing the
500MB revealed, that there's an off-by-one error in the check in
l1tf_select_mitigation().

l1tf_pfn_limit() returns the last usable pfn (inclusive) and the range
check in the mitigation path does not take this into account.

Instead of amending the range check, make l1tf_pfn_limit() return the first
PFN which is over the limit which is less error prone. Adjust the other
users accordingly.

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

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 ]

Pull clk updates from Stephen Boyd:
 "The new and exciting feature this time around is in the clk core.
  We've added duty cycle support to the clk API so that clk signal duty
  cycle ratios can be adjusted while taking into account things like clk
  dividers and clk tree hierarchy. So far only one SoC has implemented
  support for this, but I expect there will be more to come in the
  future.

  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.
  Overall it looks pretty quiet this time.

  Core:
   - Clk duty cycle support
   - Proper CLK_SET_RATE_GATE support throughout the tree

  New Drivers:
   - Actions Semi Owl series S700 SoC clk driver
   - Qualcomm SDM845 display clock controller
   - i.MX6SX ocram_s clk support
   - Uniphier NAND, USB3 PHY, and SPI clk support
   - Qualcomm RPMh clk driver

   - Renesas Crypto Engine clocks on R-Car H3
   - Renesas clk support for the new RZ/N1D SoC
   - Allwinner A64 display engine clock support
   - support for Rockchip's PX30 SoC
   - Amlogic Meson axg PCIe and audio clocks
   - Amlogic Meson GEN CLK on gxbb, gxl and axg

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"

Commit c647f806 ("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.

     existing IPSEC tunnels. From Steffen Klassert.

   - Convert GRO over to use a hash table, so that when we have many
     flows active we don't traverse a long list during accumluation.

   - Many new self tests for routing, TC, tunnels, etc. Too many
     contributors to mention them all, but I'm really happy to keep
     seeing this stuff.

   - Hardware timestamping support for dpaa_eth/fsl-fman from Yangbo Lu.

   - Lots of cleanups and fixes in L2TP code from Guillaume Nault.

   - Add IPSEC offload support to netdevsim, from Shannon Nelson.

   - Add support for slotting with non-uniform distribution to netem
     packet scheduler, from Yousuk Seung.

   - Add UDP GSO support to mlx5e, from Boris Pismenny.

   - Support offloading of Team LAG in NFP, from John Hurley.

   - Allow to configure TX queue selection based upon RX queue, from
     Amritha Nambiar.

   - Support ethtool ring size configuration in aquantia, from Anton
     Mikaev.

   - Support DSCP and flowlabel per-transport in SCTP, from Xin Long.

   - Support list based batching and stack traversal of SKBs, this is
     very exciting work. From Edward Cree.

   - Busyloop optimizations in vhost_net, from Toshiaki Makita.

   - Introduce the ETF qdisc, which allows time based transmissions. IGB
     can offload this in hardware. From Vinicius Costa Gomes.

   - Add parameter support to devlink, from Moshe Shemesh.

   - Several multiplication and division optimizations for BPF JIT in
     nfp driver, from Jiong Wang.

   - Lots of prepatory work to make more of the packet scheduler layer
     lockless, when possible, from Vlad Buslov.

   - Add ACK filter and NAT awareness to sch_cake packet scheduler, from
     Toke Høiland-Jørgensen.

   - Support regions and region snapshots in devlink, from Alex Vesker.

   - Allow to attach XDP programs to both HW and SW at the same time on
     a given device, with initial support in nfp. From Jakub Kicinski.

   - Add TLS RX offload and support in mlx5, from Ilya Lesokhin.

   - Use PHYLIB in r8169 driver, from Heiner Kallweit.

   - All sorts of changes to support Spectrum 2 in mlxsw driver, from
     Ido Schimmel.

   - PTP support in mv88e6xxx DSA driver, from Andrew Lunn.

   - Make TCP_USER_TIMEOUT socket option more accurate, from Jon
     Maxwell.

   - Support for templates in packet scheduler classifier, from Jiri
     Pirko.

   - IPV6 support in RDS, from Ka-Cheong Poon.

   - Native tproxy support in nf_tables, from Máté Eckl.

   - Maintain IP fragment queue in an rbtree, but optimize properly for
     in-order frags. From Peter Oskolkov.

   - Improvde handling of ACKs on hole repairs, from Yuchung Cheng"
