Certain GL unit tests for large textures can cause problems
with the OOM killer since there is no way to link this memory
to a process. This was originally mitigated (but not necessarily
eliminated) by limiting the GTT size. The problem is this limit
is often too low for many modern games so just make the limit 1/2
of system memory. The OOM accounting needs to be addressed, but
we shouldn't prevent common 3D applications from being usable
just to potentially mitigate that corner case.
Set default GTT size to max(3G, 1/2 of system ram) by default.
v2: drop previous logic and default to 3/4 of ram
v3: default to half of ram to align with ttm
v4: fix spelling in comment (Kent)

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged
here for calculating the size of the destination buffer (0x10 instead of
0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with
the source and dest being struct fw_section_info_st, so the memcpy should
be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's
responsibility to figure out.
Avoid the whole thing and just do a direct assignment. This results in
no change to the executable code.

BAR0 is the main (only?) register bank for this device. We most
obviously can't unmap it before the netdev is unregistered.
This was pointed out in review but the patch got reposted and
merged, anyway.
The author of the patch was only testing it with a QEMU model,
which I presume does not emulate enough for the netdev to be brought
up (author's replies are not visible in lore because they kept sending

The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call.
Complicating things, however, is that POWER8 systems need some per-cpu
state and kmalloc, which isn't available at this stage. So we split
things up into an early phase and a later opportunistic phase. This
commit also removes some noisy log messages that don't add much.

Simon reports that if two LAN9514 USB adapters are directly connected
without an intermediate switch, the link fails to come up and link LEDs
remain dark. The issue was introduced by commit 1ce8b37241 ("usbnet:
smsc95xx: Forward PHY interrupts to PHY driver to avoid polling").
The PHY suffers from a known erratum wherein link detection becomes
unreliable if Energy Detect Power-Down is used. In poll mode, the
driver works around the erratum by briefly disabling EDPD for 640 msec
to detect a neighbor, then re-enabling it to save power.
In interrupt mode, no interrupt is signaled if EDPD is used by both link
partners, so it must not be enabled at all.
We'll recoup the power savings by enabling SUSPEND1 mode on affected
LAN95xx chips in a forthcoming commit.

Commit 34a897758e ("ice: Add support for inner etype in switchdev")
added the ability to match on inner ethertype. A side effect of that change
is that it is now impossible to add some filters for protocols which do not
contain inner ethtype field. tc requires the protocol field to be specified
when providing certain other options, e.g. src_ip. This is a problem in
case of GTP - when user wants to specify e.g. src_ip, they also need to
specify protocol in tc command (otherwise tc fails with: Illegal "src_ip").
Because GTP is a tunnel, the protocol field is treated as inner protocol.
GTP does not contain inner ethtype field and the filter cannot be added.
To fix this, ignore the ethertype field in case of GTP filters.

During postsuspend dm-era does the following:
1. Archives the current era
2. Commits the metadata, as part of the RPC call for archiving the
current era
3. Stops the worker
Until the worker stops, it might write to the metadata again. Moreover,
these writes are not flushed to disk immediately, but are cached by the
dm-bufio client, which writes them back asynchronously.
As a result, the committed metadata of a suspended dm-era device might
not be consistent with the in-core metadata.
In some cases, this can result in the corruption of the on-disk
metadata. Suppose the following sequence of events:
1. Load a new table, e.g. a snapshot-origin table, to a device with a
dm-era table
2. Suspend the device
3. dm-era commits its metadata, but the worker does a few more metadata
writes until it stops, as part of digesting an archived writeset
4. These writes are cached by the dm-bufio client
5. Load the dm-era table to another device.
6. The new instance of the dm-era target loads the committed, on-disk
metadata, which don't include the extra writes done by the worker
after the metadata commit.
7. Resume the new device
8. The new dm-era target instance starts using the metadata
9. Resume the original device
10. The destructor of the old dm-era target instance is called and
destroys the dm-bufio client, which results in flushing the cached
writes to disk
11. These writes might overwrite the writes done by the new dm-era
instance, hence corrupting its metadata.
Fix this by committing the metadata after the worker stops running.
stop_worker uses flush_workqueue to flush the current work. However, the
work item may re-queue itself and flush_workqueue doesn't wait for
re-queued works to finish.
This could result in the worker changing the metadata after they have
been committed, or writing to the metadata concurrently with the commit
in the postsuspend thread.
Use drain_workqueue instead, which waits until the work and all
re-queued works finish.

Pull signature checking selftest from David Howells:
"The signature checking code, as used by module signing, kexec, etc.,
is non-FIPS compliant as there is no selftest.
For a kernel to be FIPS-compliant, signature checking would have to be
tested before being used, and the box would need to panic if it's not
available (probably reasonable as simply disabling signature checking
would prevent you from loading any driver modules).
Deal with this by adding a minimal test.
This is split into two patches: the first moves load_certificate_list()
to the same place as the X.509 code to make it more accessible
internally; the second adds a selftest"

Pull btrfs fixes from David Sterba:
- print more error messages for invalid mount option values
- prevent remount with v1 space cache for subpage filesystem
- fix hang during unmount when block group reclaim task is running
* tag 'for-5.19-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: add error messages to all unrecognized mount options
btrfs: prevent remounting to v1 space cache for subpage mount
btrfs: fix hang during unmount when block group reclaim task is running
If rq_qos_throttle() ends up blocking, then we will have invalidated and
flushed our current plug. Since blk_mq_get_cached_request() hasn't
popped the cached request off the plug list just yet, we end holding a
pointer to a request that is no longer valid. This insta-crashes with
rq->mq_hctx being NULL in the validity checks just after.
Pop the request off the cached list before doing rq_qos_throttle() to
avoid using a potentially stale request.

The recent patch to make afs_getattr consult the server didn't account
for the pseudo-inodes employed by the dynamic root-type afs superblock
not having a volume or a server to access, and thus an oops occurs if
such a directory is stat'd.
Fix this by checking to see if the vnode->volume pointer actually points
anywhere before following it in afs_getattr().
This can be tested by stat'ing a directory in /afs. It may be
sufficient just to do "ls /afs" and the oops looks something like:
BUG: kernel NULL pointer dereference, address: 0000000000000020

Nothing defined in the header is used by drivers/firmware/efi/sysfb_efi.c
but also, including it can lead to build errors when built on arches that
don't have an asm/efi.h header file.
This can happen for example if a driver that is built when COMPILE_TEST is
enabled selects the SYSFB symbol, e.g. on powerpc with allyesconfig:
drivers/firmware/efi/sysfb_efi.c:29:10: fatal error: asm/efi.h: No such file or directory

Add some selftests for signature checking when FIPS mode is enabled. These
need to be done before we start actually using the signature checking for
things and must panic the kernel upon failure.
Note that the tests must not check the blacklist lest this provide a way to
prevent a kernel from booting by installing a hash of a test key in the
appropriate UEFI table.

Move load_certificate_list(), which loads a series of binary X.509
certificates from a blob and inserts them as keys into a keyring, to be
with the asymmetric keys code that it drives.
This makes it easier to add FIPS selftest code in which we need to load up
a private keyring for the tests to use.
