The REG_FLD_MOD function takes the start and end bits as parameter and
will generate a mask out of them.
This makes it difficult to share the masks between callers, since we now
need two arguments and to keep them consistent.
Let's change REG_FLD_MOD to take the mask as an argument instead, and
let the caller create the mask. Eventually, this mask will be moved to a

The dispc driver uses upper-cased, inlined, functions to provide
macro-like accessors to the dispc registers.
This is confusing, since upper-case is usually used by macros, and that
pattern will create gcc errors later on in this series.
Let's switch to macros to make it more consistent, and prevent those

x->id.spi == 0 means "no SPI assigned", but since commit
94f39804d8 ("xfrm: Duplicate SPI Handling"), we now create states
and add them to the byspi list with this value.
__xfrm_state_delete doesn't remove those states from the byspi list,
since they shouldn't be there, and this shows up as a UAF the next
time we go through the byspi list.

Userspace jobs have drm_file.client_id as a unique identifier
as job's owners. For kernel jobs, we can allocate arbitrary
values - the risk of overlap with userspace ids is small (given
that it's a u64 value).
In the unlikely case the overlap happens, it'll only impact
trace events.
Since this ID is traced in the gpu_scheduler trace events, this
allows to determine the source of each job sent to the hardware.
To make grepping easier, the IDs are defined as they will appear
in the trace output.

Currently, hfs_brec_remove() executes moving records
towards the location of deleted record and it updates
offsets of moved records. However, the hfs_brec_remove()
logic ignores the "mess" of b-tree node's free space and
it doesn't touch the offsets out of records number.
Potentially, it could confuse fsck or driver logic or
to be a reason of potential corruption cases.
This patch reworks the logic of hfs_brec_remove()
by means of clearing freed space of b-tree node
after the records moving. And it clear the last
offset that keeping old location of free space
because now the offset before this one is keeping
the actual offset to the free space after the record
deletion.

The HFS_SB(sb)->bitmap buffer is allocated in hfs_mdb_get():
HFS_SB(sb)->bitmap = kmalloc(8192, GFP_KERNEL);
Finally, it can trigger the reported issue because kmalloc()
doesn't clear the allocated memory. If allocated memory contains
only zeros, then everything will work pretty fine.
But if the allocated memory contains the "garbage", then
it can affect the bitmap operations and it triggers
the reported issue.
This patch simply exchanges the kmalloc() on kzalloc()
with the goal to guarantee the correctness of bitmap operations.
Because, newly created allocation bitmap should have all
available blocks free. Potentially, initialization bitmap's read
operation could not fill the whole allocated memory and
"garbage" in the not initialized memory will be the reason of
volume coruptions and file system driver bugs.

Add read() and write() APIC callback functions to read and write the x2APIC
registers directly from the guest APIC backing page of a vCPU.
The x2APIC registers are mapped at an offset within the guest APIC backing
page which is the same as their x2APIC MMIO offset. Secure AVIC adds new
registers such as ALLOWED_IRRs (which are at 4-byte offset within the IRR
register offset range) and NMI_REQ to the APIC register space.
When Secure AVIC is enabled, accessing the guest's APIC registers through
RD/WRMSR results in a #VC exception (for non-accelerated register accesses)
with error code VMEXIT_AVIC_NOACCEL.
The #VC exception handler can read/write the x2APIC register in the guest APIC
backing page to complete the RDMSR/WRMSR. Since doing this would increase the
latency of accessing the x2APIC registers, instead of doing RDMSR/WRMSR based
register accesses and handling reads/writes in the #VC exception, directly
read/write the APIC registers from/to the guest APIC backing page of the vCPU
in read() and write() callbacks of the Secure AVIC APIC driver.

With Secure AVIC, the APIC backing page is owned and managed by the guest.
Allocate and initialize APIC backing page for all guest CPUs.
The NPT entry for a vCPU's APIC backing page must always be present when the
vCPU is running in order for Secure AVIC to function. A VMEXIT_BUSY is
returned on VMRUN and the vCPU cannot be resumed otherwise.
To handle this, notify GPA of the vCPU's APIC backing page to the hypervisor
by using the SVM_VMGEXIT_SECURE_AVIC GHCB protocol event. Before executing
VMRUN, the hypervisor makes use of this information to make sure the APIC
backing page is mapped in the NPT.

PCIe `port01` of t8103-j457 (iMac, M1, 2 USB-C ports, 2021) is unused
and disabled. Linux' PCI subsystem assigns the ethernet nic from
`port02` to bus 02. This results into assigning `pcie0_dart_1` from the
disabled port as iommu. The `pcie0_dart_1` instance is disabled and
probably fused off (it is on the M2 Pro Mac mini which has a disabled
PCIe port as well).
Without iommu the ethernet nic is not expected work.
Adjusts the "bus-range" and the PCIe devices "reg" property to PCI
subsystem's bus number.
Fixes: 7c77ab91b3 ("arm64: dts: apple: Add missing M1 (t8103) devices")

- Prevent the CPUID topology hierarchy detection on AMD from overwriting the
correct initial APIC ID
- Fix the case of a machine shipping without microcode in the BIOS, in the AMD
microcode loader
- Correct the Pentium 4 model range which has a constant TSC
