nvme-pci: fix error handling in nvme_pci_enable()
There are two issues in nvme_pci_enable():
1) If pci_alloc_irq_vectors() fails, device is left enabled. Fix this by
adding a goto disable statement.
2) nvme_pci_configure_admin_queue could return -ENODEV, in this case,
we will need to free IRQ properly. Otherwise the following warning
could be triggered:

nvme-pci: add NVME_QUIRK_IDENTIFY_CNS quirk to Apple T2 controllers
This mirrors the quirk added to Apple Silicon controllers in apple.c.
These controllers do not support the Active NS ID List command and
behave identically to the SoC version judging by existing user
reports/syslogs, so will need the same fix. This quirk reverts
back to NVMe 1.0 behavior and disables the broken commands.

block: don't allow splitting of a REQ_NOWAIT bio
If we split a bio marked with REQ_NOWAIT, then we can trigger spurious EAGAIN if constituent parts of that split bio end up failing request allocations. Parts will complete just fine, but just a single failure in one of the chained bios will yield an EAGAIN final result for the parent bio. Return EAGAIN early if we end up needing to split such a bio, which allows for saner recovery handling.

Commands like Write Zeros can change the contents of a namespaces without
actually transferring data. To protect against this, check the Commands
Supported and Effects log is supported by the controller for any
unprivileg command passthrough and refuse unprivileged passthrough if the
command has any effects that can change data or metadata.
Note: While the Commands Support and Effects log page has only been
mandatory since NVMe 2.0, it is widely supported because Windows requires
it for any command passthrough from userspace.

nvme-pci: fix mempool alloc size
Convert the max size to bytes to match the units of the divisor that
calculates the worst-case number of PRP entries.
The result is used to determine how many PRP Lists are required. The
code was previously rounding this to 1 list, but we can require 2 in the
worst case. In that scenario, the driver would corrupt memory beyond the
size provided by the mempool.
While unlikely to occur (you'd need a 4MB in exactly 127 phys segments
on a queue that doesn't support SGLs), this memory corruption has been
observed by kfence.

nvme-pci: fix doorbell buffer value endianness
When using shadow doorbells, the event index and the doorbell values are
written to host memory. Prior to this patch, the values written would
erroneously be written in host endianness. This causes trouble on
big-endian platforms. Fix this by adding missing endian conversions.
This issue was noticed by Guenter while testing various big-endian
platforms under QEMU[1]. A similar fix required for hw/nvme in QEMU is
up for review as well[2].

For blk-mq, queue release handler is usually called after
blk_mq_freeze_queue_wait() returns. However, the
q_usage_counter->release() handler may not be run yet at that time, so
this can cause a use-after-free.
Fix the issue by moving percpu_ref_exit() into blk_free_queue_rcu().
Since ->release() is called with rcu read lock held, it is agreed that
the race should be covered in caller per discussion from the two links.

blk-iolatency: Fix memory leak on add_disk() failures
When a gendisk is successfully initialized but add_disk() fails such as when
a loop device has invalid number of minor device numbers specified,
blkcg_init_disk() is called during init and then blkcg_exit_disk() during
error handling. Unfortunately, iolatency gets initialized in the former but
doesn't get cleaned up in the latter.
This is because, in non-error cases, the cleanup is performed by
del_gendisk() calling rq_qos_exit(), the assumption being that rq_qos
policies, iolatency being one of them, can only be activated once the disk
is fully registered and visible. That assumption is true for wbt and iocost,
but not so for iolatency as it gets initialized before add_disk() is called.
It is desirable to lazy-init rq_qos policies because they are optional
features and add to hot path overhead once initialized - each IO has to walk
all the registered rq_qos policies. So, we want to switch iolatency to lazy
init too. However, that's a bigger change. As a fix for the immediate
problem, let's just add an extra call to rq_qos_exit() in blkcg_exit_disk().
This is safe because duplicate calls to rq_qos_exit() become noop's.

loop: Fix the max_loop commandline argument treatment when it is set to 0
Currently, the max_loop commandline argument can be used to specify how
many loop block devices are created at init time. If it is not
specified on the commandline, CONFIG_BLK_DEV_LOOP_MIN_COUNT loop block
devices will be created.
The max_loop commandline argument can be used to override the value of
CONFIG_BLK_DEV_LOOP_MIN_COUNT. However, when max_loop is set to 0
through the commandline, the current logic treats it as if it had not
been set, and creates CONFIG_BLK_DEV_LOOP_MIN_COUNT devices anyway.
Fix this by starting max_loop off as set to CONFIG_BLK_DEV_LOOP_MIN_COUNT.
This preserves the intended behavior of creating
CONFIG_BLK_DEV_LOOP_MIN_COUNT loop block devices if the max_loop
commandline parameter is not specified, and allowing max_loop to
be respected for all values, including 0.
This allows environments that can create all of their required loop
block devices on demand to not have to unnecessarily preallocate loop
block devices.

block/blk-iocost (gcc13): keep large values in a new enum
Since gcc13, each member of an enum has the same type as the enum [1]. And that is inherited from its members. Provided: VTIME_PER_SEC_SHIFT = 37, VTIME_PER_SEC = 1LLU << VTIME_PER_SEC_SHIFT, ... AUTOP_CYCLE_NSEC = 10LLU * NSEC_PER_SEC, the named type is unsigned long. This generates warnings with gcc-13: block/blk-iocost.c: In function 'ioc_weight_prfill': block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int' block/blk-iocost.c: In function 'ioc_weight_show': block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' So split the anonymous enum with large values to a separate enum, so that they don't affect other members.

EFI updates for v6.2:
- Refactor the zboot code so that it incorporates all the EFI stub
logic, rather than calling the decompressed kernel as a EFI app.
- Add support for initrd= command line option to x86 mixed mode.
- Allow initrd= to be used with arbitrary EFI accessible file systems
instead of just the one the kernel itself was loaded from.
- Move some x86-only handling and manipulation of the EFI memory map
into arch/x86, as it is not used anywhere else.
- More flexible handling of any random seeds provided by the boot
environment (i.e., systemd-boot) so that it becomes available much
earlier during the boot.
- Allow improved arch-agnostic EFI support in loaders, by setting a
uniform baseline of supported features, and adding a generic magic
number to the DOS/PE header. This should allow loaders such as GRUB or
systemd-boot to reduce the amount of arch-specific handling
substantially.
- (arm64) Run EFI runtime services from a dedicated stack, and use it to
recover from synchronous exceptions that might occur in the firmware
code.
- (arm64) Ensure that we don't allocate memory outside of the 48-bit
addressable physical range.
- Make EFI pstore record size configurable
- Add support for decoding CXL specific CPER records

"Another fairly sizable pull request, by EFI subsystem standards.
Most of the work was done by me, some of it in collaboration with the
distro and bootloader folks (GRUB, systemd-boot), where the main focus
has been on removing pointless per-arch differences in the way EFI
boots a Linux kernel.
- Refactor the zboot code so that it incorporates all the EFI stub
logic, rather than calling the decompressed kernel as a EFI app.
- Add support for initrd= command line option to x86 mixed mode.
