When booting the xenbus driver will wait for PV devices to have
connected to their backends before continuing. The timeout is different
between essential and non-essential devices.
Non-essential devices are identified by their nodenames directly in the
xenbus driver, which requires to update this list in case a new device
type being non-essential is added (this was missed for several types
in the past).
In order to avoid this problem, add a "not_essential" flag to struct
xenbus_driver which can be set to "true" by the respective frontend.
Set this flag for the frontends currently regarded to be not essential
(vkbs and vfb) and use it for testing in the xenbus driver.

If a timeout is hit, it can result is incorrect data on the I2C bus

Here is, for example, the start of a slub_debug splat which was
triggered on the next transfer after one transfer was forced to timeout
by setting a breakpoint in the backend (rust-vmm/vhost-device):

There is no simple fix for this (the driver would have to always create
bounce buffers and hold on to them until the device eventually returns
the buffers), so just disable the timeout support for now.

Currently interrupt storm will occur from i2c-i801 after first
transaction if SMB_ALERT signal is enabled and ever asserted. It is
enough if the signal is asserted once even before the driver is loaded
and does not recover because that interrupt is not acknowledged.
This fix aims to fix it by two ways:
- Add acknowledging for the SMB_ALERT interrupt status
- Disable the SMB_ALERT interrupt on platforms where possible since the
driver currently does not make use for it
Acknowledging resets the SMB_ALERT interrupt status on all platforms and
also should help to avoid interrupt storm on older platforms where the
SMB_ALERT interrupt disabling is not available.
For simplicity this fix reuses the host notify feature for disabling and
restoring original register value.

If driver interrupts are enabled, SMBHSTCNT_INTREN will be 1 after
the first transaction, and will stay to that value forever. This
means that interrupts will be generated for both host-initiated
transactions and also SMBus Alert events even after the driver is
unloaded. To be on the safe side, we should restore the initial state
of this bit at suspend and reboot time, as we do for several other
configuration bits already and for the same reason: the BIOS should
be handed the device in the same configuration state in which we
received it. Otherwise interrupts may be generated which nobody

disk->fops->owner is grabbed in blkdev_get_no_open() after the disk
kobject refcount is increased. This way can't make sure that
disk->fops->owner is still alive since del_gendisk() still can move
on if the kobject refcount of disk is grabbed by open() and
disk->fops->open() isn't called yet.
Fixes the issue by moving try_module_get() into blkdev_get_by_dev()
with ->open_mutex() held, then we can drain the in-progress open()
in del_gendisk(). Meantime new open() won't succeed because disk
becomes not alive.
This way is reasonable because blkdev_get_no_open() needn't to touch
disk->fops or defined callbacks.

When __unmap_hugepage_range() calls to huge_pmd_unshare() succeed, a TLB
flush is missing. This TLB flush must be performed before releasing the
i_mmap_rwsem, in order to prevent an unshared PMDs page from being
released and reused before the TLB flush took place.
Arguably, a comprehensive solution would use mmu_gather interface to
batch the TLB flushes and the PMDs page release, however it is not an
easy solution: (1) try_to_unmap_one() and try_to_migrate_one() also call
huge_pmd_unshare() and they cannot use the mmu_gather interface; and (2)
deferring the release of the page reference for the PMDs page until
after i_mmap_rwsem is dropeed can confuse huge_pmd_unshare() into
thinking PMDs are shared when they are not.
Fix __unmap_hugepage_range() by adding the missing TLB flush, and
forcing a flush when unshare is successful.

Merge tag 'arm-soc/for-5.16/devicetree-fixes' of https://github.com/Broadcom/stblinux into arm/fixes
This pull request contains Broadcom ARM-based SoCs Device Tree fixes for
5.16, please pull the following:
- Florian fixes the BCM5310x DTS include file to have the appropriate
I2C controller interrupt line, and allows the BCMA GPIO controller to
be used as an interrupt controller. Finally, the BCM2711 (Raspberry Pi
4) PCIe Device Tree node interrupts are fixed to list the correct
interrupt output as well as the INTB/C/D lines.

This reverts commit 279917e27e.
With the CONFIG_HARDENED_USERCOPY option enabled, this patch triggers
kernel bugs at runtime:
usercopy: Kernel memory overwrite attempt detected to kernel text (offset 2084839, size 6)!
kernel BUG at mm/usercopy.c:99!
Backtrace:
IAOQ[0]: usercopy_abort+0xc4/0xe8
[<00000000406ed1c8>] __check_object_size+0x174/0x238
[<00000000407086d4>] copy_strings.isra.0+0x3e8/0x708

[<0000000040303eb8>] syscall_exit+0x0/0x14
The problem is, that we have an init section of at least 2MB size which
starts at _stext and is freed after bootup.
If then later some kernel data is (temporarily) stored in this free
memory, check_kernel_text_object() will trigger a bug since the data
appears to be inside the kernel text (>=_stext) area:
if (overlaps(ptr, len, _stext, _etext))
usercopy_abort("kernel text");

The extru instruction leaves the most significant 32 bits of the target
register in an undefined state on PA 2.0 systems. If any of these bits
are nonzero, this will break the calculation of the lock pointer.
Fix by using extrd,u instruction via extru_safe macro on 64-bit kernels.

PA-RISC uses a much bigger frame size for functions than other
architectures. So increase it to 2048 for 32- and 64-bit kernels.
This fixes e.g. a warning in lib/xxhash.c.

- Move the command line preparation and the early command line parsing
earlier so that the command line parameters which affect
early_reserve_memory(), e.g. efi=nosftreserve, are taken into
account. This was broken when the invocation of early_reserve_memory()
was moved recently.
- Use an atomic type for the SGX page accounting, which is read and
written lockless, to plug various race conditions related to it.

One item stand out and that is that I delete the <linux/sdb.h> header

Merge tag 's390-5.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
- Add missing Kconfig option for ftrace direct multi sample, so it can
be compiled again, and also add s390 support for this sample.
- Update Christian Borntraeger's email address.
- Various fixes for memory layout setup. Besides other this makes it
possible to load shared DCSS segments again.
- Fix copy to user space of swapped kdump oldmem.
- Remove -mstack-guard and -mstack-size compile options when building
vdso binaries. This can happen when CONFIG_VMAP_STACK is disabled and
results in broken vdso code which causes more or less random
exceptions. Also remove the not needed -nostdlib option.
- Fix memory leak on cpu hotplug and return code handling in kexec
code.
- Wire up futex_waitv system call.
- Replace snprintf with sysfs_emit where appropriate.
