Up until commit 7e5fbd1e07 ("net: mdio-gpio: Convert to use gpiod
functions where possible"), the _cansleep variants of the gpio_ API was
used. After that commit and the change to gpiod_ API, the _cansleep()
was dropped. This then results in WARN_ON() when used with GPIO
devices which do sleep. Add back the _cansleep() to avoid this.

These is no need to hold dst before calling rt6_remove_exception_rt().
The call to dst_hold_safe() in ip6_link_failure() was for ip6_del_rt(),
which has been removed in Commit 93531c6743 ("net/ipv6: separate
handling of FIB entries from dst based routes"). Otherwise, it will
cause a dst leak.
This patch is to simply remove the dst_hold_safe() call before calling
rt6_remove_exception_rt() and also do the same in ip6_del_cached_rt().
It's safe, because the removal of the exception that holds its dst's
refcnt is protected by rt6_exception_lock.

Using 2.5G speed relies on the SerDes lanes being configured
accordingly. The lanes have to be reconfigured to switch between
1G and 2.5G, and for now only the bootloader does this configuration.
In the case we add a Comphy driver to handle switching the lanes
dynamically, it's better for now to stick with supporting only 1G and
add advertisement for 2.5G once we really are capable of handling both
speeds without problem.
Since the interface mode is initialy taken from the DT, we want to make
sure that adding comphy support won't break boards that don't update
their dtb.

- 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

- 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.

Hardware can sometimes not generate NQ MSIX with a single pending
CP ring entry. This seems to always happen at the last entry of
the CP ring before it wraps. Add logic to check all the CP rings for
pending entries without the CP ring consumer index advancing. Calling
HWRM_DBG_RING_INFO_GET to read the context of the CP ring will flush
out the NQ entry and MSIX.

The software counter structure is defined in both the CP ring's structure
and the NQ ring's structure on the new devices. The legacy code adds the
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
sleep.
The kmalloc() call is easy enough to fix, but the memremap() call
needs to be moved into an init hook since we cannot control the
memory allocation behavior of memremap() at the call site.

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:
24d7c494ce ("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:
3ea86495ae ("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().
