This param allows forcing all dependencies to be treated as mandatory.
This will be useful for boards in which all optional dependencies like
IOMMUs and DMAs need to be treated as mandatory dependencies.

Firmware allocates memory regions for PFs and VFs in DRAM.
The PFs memory region is used for AF-PF and PF-VF mailbox.
This mbox facilitates communication between AF-PF and PF-VF.

NIX uses unique channel numbers to identify the packet sources/sinks
like CGX,LBK and SDP. The channel numbers assigned to each block are
hardwired in CN9xxx silicon.
The fixed channel numbers in CN9xxx are:
0x0 | a << 8 | b- LBK(0..3)_CH(0..63)
0x0 | a << 8

When stopping a channel, gsi_channel_stop() will ensure NAPI
polling is complete when it calls napi_disable(). So there is no
need to call napi_synchronize() in that case.
Move the call to napi_synchronize() out of __gsi_channel_stop()
and into gsi_channel_suspend(), so it's only used where

Since it's been a while, I've dropped the Reviewed-By's.
It depended on commit 83c4e7a0363b ("KUnit: KASAN Integration") which
hadn't been merged yet, so that caused some kerfuffle with applying them
previously and the series was reverted.
This revives the series but

The bus probe function dax_bus_probe() calls the probe callback without
checking it to be non-NULL. Prevent a NULL pointer exception if a driver
without a probe function is registered by refusing to register this
driver.

As per Intel TDX Virtual Firmware Design Guide, sec 4.3.5 and

The development of this patch was aided by the following coccinelle
script:
//
// SPDX-License-Identifier: GPL-2.0-only
// Find kmap/memset/kunmap pattern and replace with memset*page calls
//
// NOTE: Offsets and other expressions may be more complex than what the script
//
From: Ira Weiny
There are many places where kmap//kunmap patterns occur. We lift
these various patterns to core common functions and use them in the btrfs file
system. At the same time we convert those core functions to use
kmap_local_page() which is more efficient in those calls.
I think
An event ring's state only needs to be known when it is allocated,
reset, or deallocated. We check an event ring's state both before
and after performing an event ring control command that changes
its state. These are only issued at startup and shutdown, so there
is very little value in caching
