We want to keep the idle time fixed, so compute based on the current DDR
frequency.
The old properties were deprecated and never used, so we can safely drop
them from the driver.

All of these properties are initialized by ARM Trusted Firmware, and
have been since the early days of this chip. It's redundant (and
possibly wrong) to do this here now. What's more, there seems to be some
confusion about the units and some of the definitions of this timing
struct: the DT docs say MHz for many of these, but downstream users were
in Hz (and therefore, the ATF interface was Hz). Also, the in-driver
usage for some of these (e.g., for comparing to target frequency) were
in Hz too. So doubly wrong.
We can avoid thinking about who got the right units by dropping the
unnecessary code and properties. They are marked deprecated in the
binding schema.

These properties are:
* undocumented
* directly representing software properties, not hardware properties
* unused (no in-tree users, yet; this IP block has so far only been used
in downstream kernels)
Let's just stick the values that downstream users have been using
directly in the driver and call it a day.

I messed up the delayed takover path in the locking conversion in
6e7da3af008b ("fbcon: Move console_lock for register/unlink/unregister").
If CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER is enabled, fbcon take-over
doesn't take place when calling fbcon_fb_registered(). Instead, is deferred
using a workqueue and its fbcon_register_existing_fbs() function calls to
fbcon_fb_registered() again for each registered fbcon fb.
This leads to the console_lock tried to be held twice, causing a deadlock.
Fix it by re-extracting the lockless function and using it in the
delayed takeover path, where we need to hold the lock already to
iterate over the list of already registered fb. Well the current code
still is broken in there (since the list is protected by a
registration_lock, which we can't take here because it nests the other
way round with console_lock), but in the future this will be a list
protected by console_lock when this is all sorted out.
While reviewing the broken commit I realized that I've left some
outdated comments about the locking behind. Fix those too.

Read a record is cleared by others, but the deleted record cache entry is
still created by erst_get_record_id_next. When next enumerate the records,
get the cached deleted record, then erst_read() return -ENOENT and try to
get next record, loop back to first ID will return 0 in function
__erst_record_id_cache_add_one and then set record_id as
APEI_ERST_INVALID_RECORD_ID, finished this time read operation.
It will result in read the records just in the cache hereafter.

Quick boottime is important, so warn about sleeps greater than 10 ms.
Distribution Linux kernels reach initrd in 350 ms, so excessive delays
should be called out. 10 ms is chosen randomly, but three of such delays

Some of the fwnode APIs might return an error pointer instead of NULL
or valid fwnode handle. The result of such API call may be considered
optional and hence the test for it is usually done in a form of
fwnode = fwnode_find_reference(...);
if (IS_ERR(fwnode))
...error handling...
Nevertheless the resulting fwnode may have bumped the reference count
and hence caller of the above API is obliged to call fwnode_handle_put().
Since fwnode may be not valid either as NULL or error pointer the check
has to be performed there. This approach uglifies the code and adds
a point of making a mistake, i.e. forgetting about error point case.
To prevent this, allow an error pointer to be passed to the fwnode APIs.

Currently the sysfs interface maps the BERT error region as "memory"
(through acpi_os_map_memory()) in order to copy the error records into
memory buffers through memory operations (eg memory_read_from_buffer()).
The OS system cannot detect whether the BERT error region is part of
system RAM or it is "device memory" (eg BMC memory) and therefore it
cannot detect which memory attributes the bus to memory support (and
corresponding kernel mapping, unless firmware provides the required
information).
The acpi_os_map_memory() arch backend implementation determines the
mapping attributes. On arm64, if the BERT error region is not present in
the EFI memory map, the error region is mapped as device-nGnRnE; this
triggers alignment faults since memcpy unaligned accesses are not
allowed in device-nGnRnE regions.
The ACPI sysfs code cannot therefore map by default the BERT error
region with memory semantics but should use a safer default.
Change the sysfs code to map the BERT error region as MMIO (through
acpi_os_map_iomem()) and use the memcpy_fromio() interface to read the
error region into the kernel buffer.

get_pf_vdev() tries to check if a PF is a VFIO PF by looking at the driver:
if (pci_dev_driver(physfn) != pci_dev_driver(vdev->pdev)) {
However now that we have multiple VF and PF drivers this is no longer
reliable.
This means that security tests realted to vf_token can be skipped by
mixing and matching different VFIO PCI drivers.
Instead of trying to use the driver core to find the PF devices maintain a
linked list of all PF vfio_pci_core_device's that we have called
pci_enable_sriov() on.
When registering a VF just search the list to see if the PF is present and
record the match permanently in the struct. PCI core locking prevents a PF
from passing pci_disable_sriov() while VF drivers are attached so the VFIO
owned PF becomes a static property of the VF.
In common cases where vfio does not own the PF the global list remains
empty and the VF's pointer is statically NULL.
This also fixes a lockdep splat from recursive locking of the
vfio_group::device_lock between vfio_device_get_from_name() and
vfio_device_get_from_dev(). If the VF and PF share the same group this
would deadlock.

Commit 0fbb4d93b38b ("dm: add dm_submit_bio_remap interface") changed
the alloc_io() function to delay the initialization of struct dm_io's
orig_bio member, leaving it NULL until after the dm_io and associated
user submitted bio is processed by __split_and_process_bio(). This
change causes a NULL pointer dereference in dm_zone_map_bio() when the
original user bio is inspected to detect the need for zone append
command emulation.
Fix this NULL pointer by updating dm_zone_map_bio() to not access
->orig_bio when the same info can be accessed from the clone of the
->orig_bio _before_ any ->map processing. Save off the bio_op() and
bio_sectors() for the clone and then use the saved orig_bio_details as
needed.

During efi initialization, check if coco_secret is defined in the EFI
configuration table; in such case, register platform device
"efi_secret". This allows udev to automatically load the efi_secret
module (platform driver), which in turn will populate the
<securityfs>/secrets/coco directory in guests into which secrets were
injected.
Note that a declared address of an EFI secret area doesn't mean that
secrets where indeed injected to that area; if the secret area is not
populated, the driver will not load (but the platform device will still
be registered).

The new efi_secret module exposes the confidential computing (coco)
EFI secret area via securityfs interface.
When the module is loaded (and securityfs is mounted, typically under
/sys/kernel/security), a "secrets/coco" directory is created in
securityfs. In it, a file is created for each secret entry. The name
of each such file is the GUID of the secret entry, and its content is
the secret data.
This allows applications running in a confidential computing setting to
read secrets provided by the guest owner via a secure secret injection
mechanism (such as AMD SEV's LAUNCH_SECRET command).
Removing (unlinking) files in the "secrets/coco" directory will zero out
the secret in memory, and remove the filesystem entry. If the module is
removed and loaded again, that secret will not appear in the filesystem.

Confidential computing (coco) hardware such as AMD SEV (Secure Encrypted
Virtualization) allows a guest owner to inject secrets into the VMs
memory without the host/hypervisor being able to read them.
Firmware support for secret injection is available in OVMF, which
reserves a memory area for secret injection and includes a pointer to it
the in EFI config table entry LINUX_EFI_COCO_SECRET_TABLE_GUID.
If EFI exposes such a table entry, uefi_init() will keep a pointer to
the EFI config table entry in efi.coco_secret, so it can be used later
by the kernel (specifically drivers/virt/coco/efi_secret). It will also
appear in the kernel log as "CocoSecret=ADDRESS"; for example:
[ 0.000000] efi: EFI v2.70 by EDK II
[ 0.000000] efi: CocoSecret=0x7f22e680 SMBIOS=0x7f541000 ACPI=0x7f77e000 ACPI 2.0=0x7f77e014 MEMATTR=0x7ea0c018

Commit d9f283ae71af ("efi: Disable runtime services on RT") disabled EFI
runtime services by default when the CONFIG_PREEMPT_RT option is enabled.
The rationale for that commit is that some EFI calls could take too much
time, leading to large latencies which is an issue for Real-Time kernels.
But a side effect of that change was that now is not possible anymore to
enable the EFI runtime services by default when CONFIG_PREEMPT_RT is set,
without passing an efi=runtime command line parameter to the kernel.
Instead, let's add a new EFI_DISABLE_RUNTIME boolean Kconfig option, that
would be set to n by default but to y if CONFIG_PREEMPT_RT is enabled.
That way, the current behaviour is preserved but gives users a mechanism
to enable the EFI runtimes services in their kernels if that is required.
For example, if the firmware could guarantee bounded time for EFI calls.
Also, having a separate boolean config could allow users to disable the
EFI runtime services by default even when CONFIG_PREEMPT_RT is not set.

This is a no-op change for style and consistency and has no effect on
the binary output by the compiler. In sysreg.h fields are defined as
the register name followed by the field name and then _MASK. This
allows for grepping for fields by name rather than using magic numbers.

This is a no-op change for style and consistency and has no effect on
the binary output by the compiler. These fields already have macros
to define them so use them instead of magic numbers.

It is possible to set up dm-integrity in such a way that the
"tag_size" parameter is less than the actual digest size. In this
situation, a part of the digest beyond tag_size is ignored.
In this case, dm-integrity would write beyond the end of the
ic->recalc_tags array and corrupt memory. The corruption happened in
integrity_recalc->integrity_sector_checksum->crypto_shash_final.
Fix this corruption by increasing the tags array so that it has enough
padding at the end to accomodate the loop in integrity_recalc() being
able to write a full digest size for the last member of the tags
array.
