Opening files in /proc/pid/map_files when the current user is
CAP_CHECKPOINT_RESTORE capable in the root namespace is useful for
checkpointing and restoring to recover files that are unreachable via
the file system such as deleted files, or memfd files.

This patch introduces CAP_CHECKPOINT_RESTORE, a new capability facilitating
checkpoint/restore for non-root users.
Over the last years, The CRIU (Checkpoint/Restore In Userspace) team has
been asked numerous times if it is possible to checkpoint/restore a
process as non-root. The answer usually was: 'almost'.
The main blocker to restore a process as non-root was to control the PID
of the restored process. This feature available via the clone3 system
call, or via /proc/sys/kernel/ns_last_pid is unfortunately guarded by
CAP_SYS_ADMIN.
In the past two years, requests for non-root checkpoint/restore have
increased due to the following use cases:
* Checkpoint/Restore in an HPC environment in combination with a
resource manager distributing jobs where users are always running as
non-root. There is a desire to provide a way to checkpoint and
restore long running jobs.
* Container migration as non-root
* We have been in contact with JVM developers who are integrating
CRIU into a Java VM to decrease the startup time. These
checkpoint/restore applications are not meant to be running with
CAP_SYS_ADMIN.
We have seen the following workarounds:
* Use a setuid wrapper around CRIU:
See https://github.com/FredHutch/slurm-examples/blob/master/checkpointer/lib/checkpointer/checkpointer-suid.c
* Use a setuid helper that writes to ns_last_pid.
Unfortunately, this helper delegation technique is impossible to use
with clone3, and is thus prone to races.
See https://github.com/twosigma/set_ns_last_pid
* Cycle through PIDs with fork() until the desired PID is reached:
This has been demonstrated to work with cycling rates of 100,000 PIDs/s
See https://github.com/twosigma/set_ns_last_pid
* Patch out the CAP_SYS_ADMIN check from the kernel
* Run the desired application in a new user and PID namespace to provide
a local CAP_SYS_ADMIN for controlling PIDs. This technique has limited
use in typical container environments (e.g., Kubernetes) as /proc is
typically protected with read-only layers (e.g., /proc/sys) for
hardening purposes. Read-only layers prevent additional /proc mounts
(due to proc's SB_I_USERNS_VISIBLE property), making the use of new
PID namespaces limited as certain applications need access to /proc
matching their PID namespace.
The introduced capability allows to:
* Control PIDs when the current user is CAP_CHECKPOINT_RESTORE capable
for the corresponding PID namespace via ns_last_pid/clone3.
* Open files in /proc/pid/map_files when the current user is
CAP_CHECKPOINT_RESTORE capable in the root namespace, useful for
recovering files that are unreachable via the file system such as
deleted files, or memfd files.
See corresponding selftest for an example with clone3().

p9_read_work and p9_fd_cancelled may be called concurrently.
In some cases, req->req_list may be deleted by both p9_read_work
and p9_fd_cancelled.
We can fix it by ignoring replies associated with a cancelled
request and ignoring cancelled request if message has been received
before lock.

p9_fd_open just fgets file descriptors passed in from userspace, but
doesn't verify that they are valid for read or writing. This gets
cought down in the VFS when actually attempting a read or write, but
a new warning added in linux-next upsets syzcaller.
Fix this by just verifying the fds early on.

Currently the check on bits 25:24 on ISPSSPM0 is always 0 because
the mask and shift operations are incorrect. Fix this by shifting
by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking
with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits
to check.

vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.
This confuses Makefile.build which interprets the EFI stub as a target
$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]
Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.

Some builds of GCC enable stack protector by default. Simply removing
the arguments is not sufficient to disable stack protector, as the stack
protector for those GCC builds must be explicitly disabled. Remove the
argument removals and add -fno-stack-protector. Additionally include
missed x32 argument updates, and adjust whitespace for readability.

Use the DMA API bypass mechanism for direct window mappings. This uses
common code and speed up the direct mapping case by avoiding indirect
calls just when not using dma ops at all. It also fixes a problem where
the sync_* methods were using the bypass check for DMA allocations, but
those are part of the streaming ops.
Note that this patch loses the DMA_ATTR_WEAK_ORDERING override, which
has never been well defined, as is only used by a few drivers, which
IIRC never showed up in the typical Cell blade setups that are affected
by the ordering workaround.

Right now, there are two versions of system_global.h headers.
Both share a lot of common code. There are some ISP2401 specific
types on one of the headers, but it doesn't conflict with the
ISP2400 ones.
Also, the common code is identical.
So, remove code duplication by moving such code into a
common header.

There is an abstraction at the code in order to support
32 or 64 bits address/data length. However, for all
Atom chipsets supported by this version, the size is fixed.
So, cleanup the mess, removing the uused code and placing
the data sizes on a single place.
The end goal is to completely remove those local/global
headers, replacing them by some ISP-version dependent struct,
in order for the driver to decide what version it would need
in runtime.

The firmware on Turris MOX secure processor offers signing messages
with ECDSA private key stored in protected OTP memory.
The optimal solution would be to register an akcipher provider via
kernel's crypto API, but crypto API does not yet support accessing
akcipher API from userspace (and probably won't for some time, see
https://www.spinics.net/lists/linux-crypto/msg38388.html).
At first I tried to put this via standard sysfs API, but the way I
designed it is not compatible with sysfs's standard "one file per
attribute".
This patch therefore adds support for accessing this signature
generation mechanism via debugfs. Since CZ.NIC's Turris MOX is the only
user of this module, the potential future change to akcipher API should
not cause problems, since we can just change our userspace software then.

It has been observed that Toshiba DT01ACA family drives have
WRITE FPDMA QUEUED command timeouts and sometimes just freeze until
power-cycled under heavy write loads when their temperature is getting
polled in SCT mode. The SMART mode seems to be fine, though.
Let's make sure we don't use SCT mode for these drives then.
While only the 3 TB model was actually caught exhibiting the problem let's
play safe here to avoid data corruption and extend the ban to the whole
family.
