syzkaller and the fault injector showed that I was wrong to assume that
we could ignore percpu shadow allocation failures.
Handle failures properly. Merge all the allocated areas back into the
free list and release the shadow, then clean up and return NULL. The
shadow is released unconditionally, which relies upon the fact that the
release function is able to tolerate pages not being present.
Also clean up shadows in the recovery path - currently they are not
released, which leaks a bit of memory.

apply_to_page_range() takes an address range, and if any parts of it are
not covered by the existing page table hierarchy, it allocates memory to
fill them in.
In some use cases, this is not what we want - we want to be able to
operate exclusively on PTEs that are already in the tables.
Add apply_to_existing_page_range() for this. Adjust the walker
functions for apply_to_page_range to take 'create', which switches them
between the old and new modes.
This will be used in KASAN vmalloc.

With CONFIG_KASAN_VMALLOC=y any use of memory obtained via vm_map_ram()
will crash because there is no shadow backing that memory.
Instead of sprinkling additional kasan_populate_vmalloc() calls all over
the vmalloc code, move it into alloc_vmap_area(). This will fix
vm_map_ram() and simplify the code a bit.

The comment says "this should never fail", but it definitely can fail
when you have odd initial boot filesystems, or kernel configurations.
So get the error handling right: filp_open() returns an error pointer.

case of a NULL mount data pointer. And while I had "tested" it (and
presumably Dominik had too) that bug was hidden by me having options.

commit 781fa0a954 ("ARM: bcm: Add support for BCM2711 SoC")
breaks boot of many other platforms (e.g. OMAP or i.MX6) if
CONFIG_ARCH_BCM2835 is enabled in addition to some multiplatform
config (e.g. omap2plus_defconfig). The symptom is that the OMAP
based board does not show any activity beyond "Starting Kernel ..."
even with earlycon.
Reverting the mentioned commit makes it work again.
The real fix is to add the missing NULL sentinel to the
bcm2711_compat[] variable-length array.

because we wanted to use it in a fix. There's also a bug fix that is
going to render the 5.5 kernel's soft-RoCE driver incompatible with
all soft-RoCE versions prior, but it's required to actually implement
the protocol according to the RoCE spec and required in order for the

hardware.

Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
"This small series replaces all in-kernel calls to the
userspace-focused ksys_mount() and ksys_dup() with calls to
kernel-centric functions:
For each replacement of ksys_mount() with do_mount(), one needs to
verify that the first and third parameter (char *dev_name, char *type)
are strings allocated in kernelspace and that the fifth parameter
(void *data) is either NULL or refers to a full page (only occurence
in init/do_mounts.c::do_mount_root()). The second and fourth
parameters (char *dir_name, unsigned long flags) are passed by
ksys_mount() to do_mount() unchanged, and therefore do not require
particular care.
Moreover, instead of pretending to be userspace, the opening of
/dev/console as stdin/stdout/stderr can be implemented using in-kernel
functions as well. Thereby, ksys_dup() can be removed for good"
[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
case, but it at least removes _some_ of the users of "treat kernel
pointers as user pointers for our magical init sequence".
One day we'll hopefully be rid of it all, and can initialize our
init_thread addr_limit to USER_DS. - Linus ]

Here are 6 small fixes for some reported char/misc driver issues:
- fix build warnings with new 'awk' with the raid6 code
- 4 interconnect driver bugfixes
- binder fix for reported problem
All of these except the binder fix have been in linux-next with no
reported issues. The binder fix is "new" but Todd says it is good as he
has tested it :)

Here are two small driver core fixes to resolve some reported issues
The first is to handle the much-reported (by the build systems) problem
that superH does not boot anymore.
The second handles an issue in the new platform logic that a number of
people ran into with the automated tests in kbuild
Both of these have been in linux-next with no reported issues.
