Replace a modulo operator with the more common pattern for computing the
gfn "offset" of a huge page to fix an i386 build error.

  arch/x86/kvm/mmu/tdp_mmu.c:212: undefined reference to `__umoddi3'

In fact, almost all of tdp_mmu.c can be elided on 32-bit builds, but

435ccfa894 tcp: Prevent low rmem stalls with SO_RCVLOWAT.
With SO_RCVLOWAT, under memory pressure,
it is possible to enter a state where:

1. We have not received enough bytes to satisfy SO_RCVLOWAT.
2. We have not entered buffer pressure (see tcp_rmem_pressure()).
3. But, we do not have enough buffer space to accept more packets.

In this case, we advertise 0 rwnd (due to #3) but the application does
not drain the receive queue (no wakeup because of #1 and #2) so the
flow stalls.

Modify the heuristic for SO_RCVLOWAT so that, if we are advertising
rwnd<=rcv_mss, force a wakeup to prevent a stall.

Without this patch, setting tcp_rmem to 6143 and disabling TCP
autotune causes a stalled flow. With this patch, no stall occurs. This
is with RPC-style traffic with large messages.

df833050cc net: ipa: command payloads already mapped
IPA transactions describe actions to be performed by the IPA
hardware.  Three cases use IPA transactions:  transmitting a socket
buffer; providing a page to receive packet data; and issuing an IPA
immediate command.  An IPA transaction contains a scatter/gather
list (SGL) to hold the set of actions to be performed.

We map buffers in the SGL for DMA at the time they are added to the
transaction.  For skb TX transactions, we fill the SGL with a call
to skb_to_sgvec().  Page RX transactions involve a single page
pointer, and that is recorded in the SGL with sg_set_page().  In
both of these cases we then map the SGL for DMA with a call to
dma_map_sg().

Immediate commands are different.  The payload for an immediate
command comes from a region of coherent DMA memory, which must
*not* be mapped for DMA.  For that reason, gsi_trans_cmd_add()
sort of hand-crafts each SGL entry added to a command transaction.

This patch fixes a problem with the code that crafts the SGL entry
for an immediate command.  Previously a portion of the SGL entry was
updated using sg_set_buf().  However this is not valid because it
includes a call to virt_to_page() on the buffer, but the command
buffer pointer is not a linear address.

Since we never actually map the SGL for command transactions, there
are very few fields in the SGL we need to fill.  Specifically, we
only need to record the DMA address and the length, so they can be
used by __gsi_trans_commit() to fill a TRE.  We additionally need to
preserve the SGL flags so for_each_sg() still works.  For that we
can simply assign a null page pointer for command SGL entries.

9c5743dff4 x86/uaccess: fix code generation in put_user()
Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:

  You can define a local register variable and associate it with a
  specified register...

  The only supported use for this feature is to specify registers for
  input and output operands when calling Extended asm (see Extended
  Asm). This may be necessary if the constraints for a particular
  machine don't provide sufficient control to select the desired
  register.

On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
into the %edx:%eax pair, while all other cases will just use the single
register %eax (%rax on x86-64).  While the _ASM_AX actually just expands
to "%eax", note this comment next to get_user() which does something
very similar:

 * The use of _ASM_DX as the register specifier is a bit of a
 * simplification, as gcc only cares about it as the starting point
 * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
 * (%ecx being the next register in gcc's x86 register sequence), and
 * %rdx on 64 bits.

However, getting this to work requires that there is no code between the
assignment to the local register variable and its use as an input to the
asm() which can possibly clobber any of the registers involved -
including evaluation of the expressions making up other inputs.

In the current code, the ptr expression used directly as an input may
cause such code to be emitted.  For example, Sean Christopherson
observed that with KASAN enabled and ptr being current->set_child_tid
(from chedule_tail()), the load of current->set_child_tid causes a call
to __asan_load8() to be emitted immediately prior to the __put_user_4
call, and Naresh Kamboju reports that various mmstress tests fail on
KASAN-enabled builds.

It's also possible to synthesize a broken case without KASAN if one uses
"foo()" as the ptr argument, with foo being some "extern u64 __user
*foo(void);" (though I don't know if that appears in real code).

Fix it by making sure ptr gets evaluated before the assignment to
__val_pu, and add a comment that __val_pu must be the last thing
computed before the asm() is entered.

2e4564b31b smb3: add support for stat of WSL reparse points for special file types

misinterpret various special files created by Linux (WSL) as symlinks.
An earlier patch addressed readdir.  This patch fixes stat (getattr).

 "Cross-tree/merge window issues:

   - rtl8150: don't incorrectly assign random MAC addresses; fix late in
     the 5.9 cycle started depending on a return code from a function
     which changed with the 5.10 PR from the usb subsystem

  Current release regressions:

   - Revert "virtio-net: ethtool configurable RXCSUM", it was causing
     crashes at probe when control vq was not negotiated/available

  Previous release regressions:

   - ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
     bus, only first device would be probed correctly

   - nexthop: Fix performance regression in nexthop deletion by
     effectively switching from recently added synchronize_rcu() to
     synchronize_rcu_expedited()

   - netsec: ignore 'phy-mode' device property on ACPI systems; the
     property is not populated correctly by the firmware, but firmware
     configures the PHY so just keep boot settings

  Previous releases - always broken:

   - tcp: fix to update snd_wl1 in bulk receiver fast path, addressing

   - icmp: randomize the global rate limiter to prevent attackers from

   - r8169: fix operation under forced interrupt threading, make the
     driver always use hard irqs, even on RT, given the handler is light
     and only wants to schedule napi (and do so through a _irqoff()
     variant, preferably)

   - tipc: re-configure queue limit for broadcast link

   - net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN

   - fix various issues in chelsio inline tls driver

44a4c9e443 parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage
The commit 75ae04206a ("parisc: Define O_NONBLOCK to become
000200000") changed the O_NONBLOCK constant to have only one bit set
(like all other architectures). This change broke some existing
userspace code (e.g.  udevadm, systemd-udevd, elogind) which called
specific syscalls which do strict value checking on their flag
parameter.

This patch adds wrapper functions for the relevant syscalls. The
wrappers masks out any old invalid O_NONBLOCK flags, reports in the
syslog if the old O_NONBLOCK value was used and then calls the target
syscall with the new O_NONBLOCK value.

However, the driver from the 3.10 vendor kernel does not use the
following four interrupt lines:
- INT_MALI_PP3
- INT_MALI_PP3_MMU
- INT_MALI_PP7
- INT_MALI_PP7_MMU

Drop the "pp3" and "ppmmu3" interrupt lines. This is also important
because there is no matching entry in interrupt-names for it (meaning
the "pp2" interrupt is actually assigned to the "pp3" interrupt line).

Pull more arm64 updates from Will Deacon:
 "A small selection of further arm64 fixes and updates. Most of these
  are fixes that came in during the merge window, with the exception of
  the HAVE_MOVE_PMD mremap() speed-up which we discussed back in 2018
  and somehow forgot to enable upstream.

   - Improve performance of Spectre-v2 mitigation on Falkor CPUs (if
     you're lucky enough to have one)

   - Select HAVE_MOVE_PMD. This has been shown to improve mremap()
     performance, which is used heavily by the Android runtime GC, and
     it seems we forgot to enable this upstream back in 2018.

   - Ensure linker flags are consistent between LLVM and BFD

   - Fix stale comment in Spectre mitigation rework

   - Fix broken copyright header

   - Fix KASLR randomisation of the linear map

   - Prevent arm64-specific prctl()s from compat tasks (return -EINVAL)"
