Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

According to the CRB over FF-A specification [1], a TPM that implements
the ABI must comply with the TCG PTP specification. This requires support
for the Idle and Ready states.
This patch implements CRB control area requests for goIdle and
cmdReady on FF-A based TPMs.
The FF-A message used to notify the TPM of CRB updates includes a
locality parameter, which provides a hint to the TPM about which
locality modified the CRB. This patch adds a locality parameter
to __crb_go_idle() and __crb_cmd_ready() to support this.

commit 337bf13aa9dda ("PCI/VGA: Replace vga_is_firmware_default() with a
screen info check") introduced an implicit dependency upon SCREEN_INFO by
removing the open coded implementation.
If a user didn't have CONFIG_SCREEN_INFO set, vga_is_firmware_default()
would now return false. SCREEN_INFO is only used on X86 so add a
conditional select for SCREEN_INFO to ensure that the VGA arbiter works as
intended.

- Explicitly encode the XZR register if the value passed to
write_sysreg_s() is 0.
The GIC CDEOI instruction is encoded as a system register write with
XZR as the source register. However, clang does not honour the "Z"
register constraint, leading to incorrect code generation

exit_to_user_mode().
With pseudo-NMIs, interrupts are (additionally) masked at the PMR_EL1

Since commit 54f45a30c0d0 ("PCI/MSI: Add startup/shutdown for per
device domains") set callback irq_startup() and irq_shutdown() of
the struct pci_msi[x]_template, __irq_startup() will always invokes
irq_startup() callback instead of irq_enable() callback overridden
in vmd_init_dev_msi_info(). This will not start the IRQ correctly.
Also override irq_startup()/irq_shutdown() in vmd_init_dev_msi_info(),
so the irq_startup() can invoke the real logic.

We intend that EL0 exception handlers unmask all DAIF exceptions
before calling exit_to_user_mode().
When completing single-step of a suspended breakpoint, we do not call
local_daif_restore(DAIF_PROCCTX) before calling exit_to_user_mode(),
leaving all DAIF exceptions masked.
When pseudo-NMIs are not in use this is benign.
When pseudo-NMIs are in use, this is unsound. At this point interrupts
are masked by both DAIF.IF and PMR_EL1, and subsequent irq flag
manipulation may not work correctly. For example, a subsequent
local_irq_enable() within exit_to_user_mode_loop() will only unmask
interrupts via PMR_EL1 (leaving those masked via DAIF.IF), and
anything depending on interrupts being unmasked (e.g. delivery of
signals) will not work correctly.
This was detected by CONFIG_ARM64_DEBUG_PRIORITY_MASKING.
Move the call to `try_step_suspended_breakpoints()` outside of the check
so that interrupts can be unmasked even if we don't call the step handler.

KASAN reports a stack-out-of-bounds access in validate_region_offset()
while running the cxl-poison.sh unit test because the printk format
specifier, %pr format, is not a match for the resource_size_t type of
the variables. %pr expects struct resource pointers and attempts to
dereference the structure fields, reading beyond the bounds of the
stack variables.
Since these messages emit an 'A exceeds B' type of message, keep
the resource_size_t's and use the %pa specifier to be architecture
safe.

The commit a43ac325c7cb ("PCI: Set up bridge resources earlier") moved
bridge window resources set up earlier than before. The change was
necessary to support another change that got pulled on the last minute
due to breaking s390 and other systems.
The presence of valid bridge window resources earlier than before allows
pci_assign_unassigned_root_bus_resources() call from pci_host_probe()
assign the bridge windows. Some host bridges, however, have to wait first
for the link up event before they can enumerate successfully (see e.g.
qcom_pcie_global_irq_thread()) and thus the bus has not been enumerated yet
while calling pci_host_probe().
Calling pci_assign_unassigned_root_bus_resources() without results from
enumeration can result in sizing bridge windows with too small sizes which
cannot be later corrected after the enumeration has completed because
bridge windows have become pinned in place by the other resources.
Interestingly, it seems pci_read_bridge_bases() is not called at all in the
problematic case and the bridge window resource type setup is done by
pci_bridge_check_ranges() and sizing by the usual resource fitting logic.
The root problem behind all this looks pretty generic. If resource fitting
is called too early, the hotplug reservation and old size lower bounding
cause the bridge windows to be assigned without children but with non-zero
size, which leads to these pinning problems. As such, this can likely be
solved on the general level but the solution does not look trivial.
As the commit a43ac325c7cb ("PCI: Set up bridge resources earlier") was
prequisite for other change that did not end up into kernel yet, revert it
to resolve the resource assignment failures and give time to code and test
a generic solution.
