There's a lot of code here that hard-codes that the
data is a single page, and right now that seems to
be sufficient, but to make it easier to change this
in the future, add a new STUB_DATA_PAGES constant
and use it throughout the code.

Since printf() cannot be used in kernel threads (it
uses too much stack space) don't export it for modules
either.
This should leave us exporting only things that are
absolutely critical (such as memset and friends) and
things that are injected by the compiler (stack guard
and similar.)

Instead of exporting the set of functions provided by
glibc that are needed for hostfs_user.c, just build that
into the kernel image whenever hostfs is built, and then
export _those_ functions cleanly, to be independent of
the libc implementation.

The reason for triggering this warning is __block_write_full_page()
-> i_size_read(inode) - 1 overflow.
inode->i_size is assigned in __nbd_ioctl() -> nbd_set_size() -> bytesize.
We think it is necessary to limit the size of arg to prevent errors.
Moreover, __nbd_ioctl() -> nbd_add_socket(), arg will be cast to int.
Assuming the value of arg is 0x80000000000000001) (on a 64-bit machine),
it will become 1 after the coercion, which will return unexpected results.
Fix it by adding checks to prevent passing in too large numbers.

Commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status")
checked the firmware device status for both DT and ACPI devices. That
caused a regression in some ACPI systems. The exact reason isn't clear.
It's possibly a firmware bug. For now, at least, refactor the check to
be for DT based systems only.
Note that the original implementation leaked a refcount which is now
correctly handled.

warn_on_s0ix_failures will be utilized solely for messaging by

Userspace can't easily discover how much of a sleep cycle was spent in a
hardware sleep state without using kernel tracing and vendor specific sysfs
or debugfs files.
To make this information more discoverable, introduce 3 new sysfs files:
1) The time spent in a hw sleep state for last cycle.
2) The time spent in a hw sleep state since the kernel booted
3) The maximum time that the hardware can report for a sleep cycle.
All of these files will be present only if the system supports s2idle.

Although pKVM supports CPU PMU emulation for non-protected guests since
722625c6f4c5 ("KVM: arm64: Reenable pmu in Protected Mode"), this relies
on the PMU driver probing before the host has de-privileged so that the
'kvm_arm_pmu_available' static key can still be enabled by patching the
hypervisor text.
As it happens, both of these events hang off device_initcall() but the
PMU consistently won the race until 7755cec63ade ("arm64: perf: Move
PMUv3 driver to drivers/perf"). Since then, the host will fail to boot
when pKVM is enabled:

Fix the race properly by deferring the de-privilege step to

the core hypervisor initialisation path.

When the kvm module is unloaded, zpci_setup_aipb() perists some data in the
zpci_aipb structure in s390 pci code. Note that this struct is also passed
to firmware in the zpci_set_irq_ctrl() call and thus the GAIT must be a
physical address.
On module re-insertion, the GAIT is restored from this structure in
zpci_reset_aipb(). But it is a physical address, hence this may cause
issues when the kvm module is unloaded and loaded again.
Fix virtual vs physical address confusion (which currently are the same) by
adding the necessary physical-to-virtual-conversion in zpci_reset_aipb().

The APCB is part of the CRYCB.
The calculation of the APCB origin can be done by adding
the APCB offset to the CRYCB origin.
Current code makes confusing transformations, converting

Convert the driver to immutable irq-chip with a bit of
intuition. Switch some call to use irqd_to_hwirq() in the
process.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
Last minute patch for correct the pasue/resume operation with IPC4. The
issues are hardto reproduce and needs extended stress testing to be hit,
in which case the audio breaks due to DMA errors.

Add some plumbing to the zboot EFI header generation to set the newly
introduced DllCharacteristicsEx flag associated with forward edge CFI
enforcement instructions (BTI on arm64, IBT on x86)
x86 does not currently uses the zboot infrastructure, so let's wire it
up only for arm64.

We don't really care about the size of the decompressed image - what
matters is how much space needs to be allocated for the image to
execute, and this includes space for BSS that is not part of the
loadable image and so it is not accounted for in the decompressed size.
So let's add some zero padding to the end of the image: this compresses
well, and it ensures that BSS is accounted for, and as a bonus, it will
be zeroed before launching the image.
Since all architectures that implement support for EFI zboot carry this
value in the header in the same location, we can just grab it from the
binary that is being compressed.

UEFI heavily relies on so-called protocols, which are essentially
tables populated with pointers to executable code, and these are invoked
indirectly using BR or BLR instructions.
This makes the EFI execution context vulnerable to attacks on forward
edge control flow, and so it would help if we could enable hardware
enforcement (BTI) on CPUs that implement it.
So let's no longer disable BTI codegen for the EFI stub, and set the
newly introduced PE/COFF header flag when the kernel is built with BTI
landing pads.

The latest version of your favorite fork of the PE/COFF spec includes a
new type of header flag that is intended to be used in the context of
EFI firmware to indicate to the image loader that the executable regions
of an image can be mapped with BTI/IBT enforcement enabled.
So let's import these definitions so we can use them in subsequent
patches.

When wx_alloc_page_pool() failed in wx_setup_rx_resources(), it doesn't
release DMA buffer. Add dma_free_coherent() in the error path to release
the DMA buffer.

Commit 2d786e66c966 ("block: ublk: switch to ioctl command encoding")
starts to reset local variable of 'ret' as zero, then if any failure
happens when handling the three IO commands, 0 can be returned to ublk
server.
Fix it by returning -EINVAL in case of command handling failure.

This reverts commit 23f3e3272e7a4d9fb870485cd6df1e4f9539282c.
blk-mq sched bio merge still needs request to grab queue usage counter,
so we can't simply call blk_mq_attempt_bio_merge() when queue usage
counter isn't held.
