Pull powerpc fixes from Michael Ellerman:
"Two weeks worth of fixes since rc1.
- I broke 16-byte alignment of the stack when we moved PPR into
pt_regs. Despite being required by the ABI this broke almost
nothing, we eventually hit it in code where GCC does arithmetic on
the stack pointer assuming the bottom 4 bits are clear. Fix it by
padding the in-kernel pt_regs by 8 bytes.
- A couple of commits fixing minor bugs in the recent SLB rewrite.
- A build fix related to tracepoints in KVM in some configurations.
- Our old "IO workarounds" code written for Cell couldn't coexist in
a kernel that runs on Power9 with the Radix MMU, fix that.
- Remove the NPU DMA ops, these just printed a warning and should
never have been called.
- Suppress an overly chatty message triggered by CPU hotplug in some
configs.
- Two small selftest fixes.

When re-registering a user mr, the mpt information for the
existing mr when running SRIOV is obtained via the QUERY_MPT
fw command. The returned information includes the mpt's lkey.
This retrieved mpt information is used to move the mpt back
to hardware ownership in the rereg flow (via the SW2HW_MPT
fw command when running SRIOV).
The fw API spec states that for SW2HW_MPT, the lkey field
must be zero. Any ConnectX-3 PF driver which checks for strict spec
adherence will return failure for SW2HW_MPT if the lkey field is not
zero (although the fw in practice ignores this field for SW2HW_MPT).
Thus, in order to conform to the fw API spec, set the lkey field to zero
before invoking SW2HW_MPT when running SRIOV.

The life-checking function, which is used by kAFS to make sure that a call
is still live in the event of a pending signal, only samples the received
packet serial number counter; it doesn't actually provoke a change in the
counter, rather relying on the server to happen to give us a packet in the
time window.
Fix this by adding a function to force a ping to be transmitted.
kAFS then keeps track of whether there's been a stall, and if so, uses the
new function to ping the server, resetting the timeout to allow the reply
to come back.
If there's a stall, a ping and the call is *still* stalled in the same
place after another period, then the call will be aborted.

The software counter structure is defined in both the CP ring's structure

counter to the CP ring's structure and the counter won't get displayed
since the ethtool code is looking at the NQ ring's structure.
Since all other counters are contained in the NQ ring's structure, it
makes more sense to count rx_l4_csum_errors in the NQ.

Recent commit has added the reservation of RSS context. This requires
bnxt_hwrm_vnic_qcaps() to be called before allocating any RSS contexts.
The bnxt_hwrm_vnic_qcaps() call sets up proper flags that will
determine how many RSS contexts to allocate to support NTUPLE.
This causes a regression that too many RSS contexts are being reserved
and causing resource shortage when enabling many VFs. Fix it by calling
bnxt_hwrm_vnic_qcaps() earlier.

Currently the selftest wild_bctr can fail to build when an old gcc is
used, notably on gcc using a binutils version <= 2.27, because the
assembler does not support the integer suffix UL.
This patch adjusts the wild_bctr test so the REG_POISON value is still
treated as an unsigned long for the shifts on compilation but the UL
suffix is absent on the stringification, so the inline asm code
generated has no UL suffixes.

Currently, efi_mem_reserve_persistent() may not be called from atomic
context, since both the kmalloc() call and the memremap() call may

The kmalloc() call is easy enough to fix, but the memremap() call

The new memory EFI reservation feature we introduced to allow memory
reservations to persist across kexec may trigger an unbounded number
of calls to memblock_reserve(). The memblock subsystem can deal with
this fine, but not before memblock resizing is enabled, which we can
only do after paging_init(), when the memory we reallocate the array
into is actually mapped.
So break out the memreserve table processing into a separate routine
and call it after paging_init() on arm64. On ARM, because of limited
reviewing bandwidth of the maintainer, we cannot currently fix this,
so instead, disable the EFI persistent memreserve entirely on ARM so
we can fix it later.

Commit:
24d7c494ce46 ("efi/arm-stub: Round up FDT allocation to mapping size")
increased the allocation size for the FDT image created by the stub to a
fixed value of 2 MB, to simplify the former code that made several
attempts with increasing values for the size. This is reasonable
given that the allocation is of type EFI_LOADER_DATA, which is released
to the kernel unless it is explicitly memblock_reserve()d by the early
boot code.
However, this allocation size leaked into the 'size' field of the FDT
header metadata, and so the entire allocation remains occupied by the
device tree binary, even if most of it is not used to store device tree
information.
So call fdt_pack() to shrink the FDT data structure to its minimum size
after populating all the fields, so that the remaining memory is no
longer wasted.

Commit:
3ea86495aef2 ("efi/arm: preserve early mapping of UEFI memory map longer for BGRT")
deferred the unmap of the early mapping of the UEFI memory map to
accommodate the ACPI BGRT code, which looks up the memory type that
backs the BGRT table to validate it against the requirements of the UEFI spec.
Unfortunately, this causes problems on ARM, which does not permit
early mappings to persist after paging_init() is called, resulting
in a WARN() splat. Since we don't support the BGRT table on ARM anway,
let's revert ARM to the old behaviour, which is to take down the
early mapping at the end of efi_init().

Commit 4c2de74cc869 ("powerpc/64: Interrupts save PPR on stack rather

which causes the interrupt frame allocation on kernel entry to put the
kernel stack out of alignment.
Quadword (16-byte) alignment for the stack is required by both the
64-bit v1 ABI (v1.9 § 3.2.2) and the 64-bit v2 ABI (v1.1 § 2.2.2.1).
Add a pad field to fix alignment, and add a BUILD_BUG_ON to catch this

Pull RISC-V fixes from Palmer Dabbelt:
"This contains a few patches that fix various issues in the RISC-V
port:
- enable printk timestamps in the RISC-V defconfig.
- a whitespace fix to "struct pt_regs".
- add a "vdso_install" target for RISC-V.
- a pair of build fixes: one to fix a typo in our makefile, and one
to clean up some warnings.
There will probably be more patches from us for 4.20, but I don't have
anything that's ready to go right now so I'm going to hold off a bit.
Right now the only concrete thing I know I want to make sure gets
sorted out is our 32-bit stat interface, which I don't want sitting in
limbo for another cycle as we have to get RV32I glibc sone"

SMC-D stress workload showed connection stalls. Since the firmware
decides to skip raising an interrupt if the SBA DMBE mask bit is
still set, this SBA DMBE mask bit should be cleared before the
IRQ handling in the SMC code runs. Otherwise there are small windows
possible with missing interrupts for incoming data.
SMC-D currently does not care about the old value of the SBA DMBE
mask.

"These remove a stale DT entry left behind after recent removal of a
cpufreq driver without users, fix up error handling in the imx6q
cpufreq driver, fix two issues in the cpufreq documentation, and
update the ARM cpufreq driver.
Specifics:
- Drop stale DT binding for the arm_big_little_dt driver removed
recently (Sudeep Holla).
- Fix up error handling in the imx6q cpufreq driver to make it report
voltage scaling failures (Anson Huang).
- Fix two issues in the cpufreq documentation (Viresh Kumar, Zhao Wei
Liew).
- Fix ARM cpuidle driver initialization regression from the 4.19 time
frame and rework the driver registration part of it to simplify
code (Ulf Hansson)"

Pull namespace fix from Eric Biederman:
"Benjamin Coddington noticed an unkillable busy loop in the kernel that
anyone who is sufficiently motivated can trigger. This bug did not
exist in earlier kernels making this bug a regression.
I have tested the change personally and confirmed that the bug exists
and that the fix works. This fix has been picked up by linux-next and
hopefully the automated testing bots and no problems have been
reported from those sources.
Ordinarily I would let something like this sit a little longer but I
am going to be away at Linux Plumbers the rest of this week and I am
afraid if I don't send the pull request now this fix will get lost"
