Pull x86 alternatives/paravirt updates from Borislav Petkov:
"First big cleanup to the paravirt infra to use alternatives and thus
eliminate custom code patching.
For that, the alternatives infrastructure is extended to accomodate
paravirt's needs and, as a result, a lot of paravirt patching code
goes away, leading to a sizeable cleanup and simplification.
Work by Juergen Gross"

In null_init, null_add_dev(dev) is called.
In null_add_dev, it calls null_free_zoned_dev(dev) to free dev->zones
via kvfree(dev->zones) in out_cleanup_zone branch and returns err.
Then null_init accept the err code and then calls null_free_dev(dev).
But in null_free_dev(dev), dev->zones is freed again by
null_free_zoned_dev().
My patch set dev->zones to NULL in null_free_zoned_dev() after
kvfree(dev->zones) is called, to avoid the double free.

In command queueing mode, the cache isn't flushed via the mmc_flush_cache()
function, but instead by issuing a CMDQ_TASK_MGMT (CMD48) with a
FLUSH_CACHE opcode. In this path, we need to check if cache has been
enabled, before deciding to flush the cache, along the lines of what's
being done in mmc_flush_cache().
To fix this problem, let's add a new bus ops callback ->cache_enabled() and
implement it for the mmc bus type. In this way, the mmc block device driver
can call it to know whether cache flushing should be done.

The value was never checked here, and the purpose of the function
is only to flush the contents, so restore the old behavior but
add a cast to void and a comment, which hopefully warns with neither
gcc nor clang now.
If anyone has an idea for how to fix it without ignoring the return
code, that is probably better.

When the PF is no longer enforcing an assigned MAC address on a VF, the
VF needs to call bnxt_approve_mac() to tell the PF what MAC address it is
now using. Otherwise it gets out of sync and the PF won't know what
MAC address the VF wants to use. Ultimately the VF will fail when it
tries to setup the L2 MAC filter for the vnic.

Firmware previously only allowed promiscuous mode for VFs associated with
a default VLAN. It is now possible to enable promiscuous mode for a VF
having no VLAN configured provided that it is trusted. In such cases the
VF will see all packets received by the PF, irrespective of destination
MAC or VLAN.
Note, it is necessary to query firmware at the time of bnxt_promisc_ok()
instead of in bnxt_hwrm_func_qcfg() because the trusted status might be
altered by the PF after the VF has been configured. This check must now
also be deferred because the firmware call sleeps.

In the current code, the driver will not shutdown the link during
IFDOWN if there are still VFs sharing the port. Newer firmware will
manage the link down decision when the port is shared by VFs, so
we can just call firmware to shutdown the port unconditionally and

Copy the phy related feature flags from the firmware call
HWRM_PORT_PHY_QCAPS to this new field. We can also remove the flags
field in the bnxt_test_info structure. It's cleaner to have all PHY
related flags in one location, directly copied from the firmware.
To keep the BNXT_PHY_CFG_ABLE() macro logic the same, we need to make
a slight adjustment to check that it is a PF.

The default behavior for source MACVLAN is to duplicate packets to
appropriate type source devices, and then do the normal destination MACVLAN
flow. This patch adds an option to skip destination MACVLAN processing if
any matching source MACVLAN device has the option set.
This allows setting up a "catch all" device for source MACVLAN: create one
or more devices with type source nodst, and one device with e.g. type vepa,
and incoming traffic will be received on exactly one device.

Saeed Mahameed says:
====================
mlx5-updates-2021-04-21
devlink external port attribute for SF (Sub-Function) port flavour
This adds the support to instantiate Sub-Functions on external hosts
E.g when Eswitch manager is enabled on the ARM SmarNic SoC CPU, users
are now able to spawn new Sub-Functions on the Host server CPU.
Parav Pandit Says:
==================
This series introduces and uses external attribute for the SF port to
indicate that a SF port belongs to an external controller.
This is needed to generate unique phys_port_name when PF and SF numbers
are overlapping between local and external controllers.
For example two controllers 0 and 1, both of these controller have a SF.
having PF number 0, SF number 77. Here, phys_port_name has duplicate
entry which doesn't have controller number in it.
Hence, add controller number optionally when a SF port is for an
external controller. This extension is similar to existing PF and VF
eswitch ports of the external controller.
When a SF is for external controller an example view of external SF
port and config sequence:
On eswitch system:
$ devlink dev eswitch set pci/0033:01:00.0 mode switchdev
$ devlink port show
pci/0033:01:00.0/196607: type eth netdev enP51p1s0f0np0 flavour physical port 0 splittable false
pci/0033:01:00.0/131072: type eth netdev eth0 flavour pcipf controller 1 pfnum 0 external true splittable false
function:
hw_addr 00:00:00:00:00:00
$ devlink port add pci/0033:01:00.0 flavour pcisf pfnum 0 sfnum 77 controller 1
pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 splittable false
function:
hw_addr 00:00:00:00:00:00 state inactive opstate detached
phys_port_name construction:
$ cat /sys/class/net/eth1/phys_port_name
c1pf0sf77
Patch summary:
First 3 patches prepares the eswitch to handle vports in more generic
way using xarray to lookup vport from its unique vport number.
Patch-1 returns maximum eswitch ports only when eswitch is enabled
Patch-2 prepares eswitch to return eswitch max ports from a struct
Patch-3 uses xarray for vport and representor lookup
Patch-4 considers SF for an additioanl range of SF vports
Patch-5 relies on SF hw table to check SF support
Patch-6 extends SF devlink port attribute for external flag
Patch-7 stores the per controller SF allocation attributes
Patch-8 uses SF function id for filtering events
Patch-9 uses helper for allocation and free
Patch-10 splits hw table into per controller table and generic one
Patch-11 extends sf table for additional range

Add a platform data bool to tell us whether to

as the corresponding NPE.
We need to drop the memory region request as part of

Currently the netvsc/VF binding logic only checks the PCI serial number.
The Microsoft Azure Network Adapter (MANA) supports multiple net_device
interfaces (each such interface is called a "vPort", and has its unique
MAC address) which are backed by the same VF PCI device, so the binding
logic should check both the MAC address and the PCI serial number.
The change should not break any other existing VF drivers, because
Hyper-V NIC SR-IOV implementation requires the netvsc network
interface and the VF network interface have the same MAC address.

In bnxt_rx_pkt(), the RX buffers are expected to complete in order.
If the RX consumer index indicates an out of order buffer completion,
it means we are hitting a hardware bug and the driver will abort all
remaining RX packets and reset the RX ring. The RX consumer index
that we pass to bnxt_discard_rx() is not correct. We should be
passing the current index (tmp_raw_cons) instead of the old index
(raw_cons). This bug can cause us to be at the wrong index when
trying to abort the next RX packet. It can crash like this:

Supporting SF allocation is currently checked at two places:
(a) SF devlink port allocator and
(b) SF HW table handler.
Both layers are using HCA CAP to identify it using helper routine
mlx5_sf_supported() and mlx5_sf_max_functions().
Instead, rely on the HW table handler to check if SF is supported
or not.

Currently vport number to vport and its representor are mapped using an
array and an index.
Vport numbers of different types of functions are not contiguous. Adding
new such discontiguous range using index and number mapping is increasingly
complex and hard to maintain.
Hence, maintain an xarray of vport and rep whose lookup is done based on
the vport number.
Each VF and SF entry is marked with a xarray mark to identify the function
type. Additionally PF and VF needs special handling for legacy inline
mode. They are additionally marked as host function using additional
HOST_FN mark.

Total vports are already stored during eswitch initialization. Instead
of calculating everytime, read directly from eswitch.
Additionally, host PF's SF vport information is available using
QUERY_HCA_CAP command. It is not available through HCA_CAP of the
eswitch manager PF.
Hence, this patch prepares the return total eswitch vport count from the
existing eswitch struct.
This further helps to keep eswitch port counting macros and logic within
eswitch.
