Add SPDX GPL-2.0 to all PCI files that referred to the kernel default
"COPYING" file, which specifies GPL version 2.
Remove the boilerplate language referring to the GPL and "COPYING", relying
on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0
license identifier to files with no license") that the SPDX identifier may
be used instead of the full boilerplate text.

b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to
files with no license") added SPDX GPL-2.0 to several PCI files that
previously contained no license information.
Add SPDX GPL-2.0 to all other PCI files that did not contain any license
information and hence were under the default GPL version 2 license of the
kernel.

This reverts commit 04e35f4495dd560db30c25efca4eecae8ec8c375.
SELinux runs with secureexec for all non-"noatsecure" domain transitions,
which means lots of processes end up hitting the stack hard-limit change
that was introduced in order to fix a race with prlimit(). That race fix
will need to be redesigned.

Pull Page Table Isolation (PTI) v4.14 backporting base tree from Ingo Molnar:
"This tree contains the v4.14 PTI backport preparatory tree, which
consists of four merges of upstream trees and 7 cherry-picked commits,
which the upcoming PTI work depends on"
NOTE! The resulting tree is exactly the same as the original base tree
(ie the diff between this commit and its immediate first parent is
empty).
The only reason for this merge is literally to have a common point for
the actual PTI changes so that the commits can be shared in both the
4.15 and 4.14 trees.

[ Note, this is a Git cherry-pick of the following commit:
d17a1d97dc20: ("x86/mm/kasan: don't use vmemmap_populate() to initialize shadow")
... for easier x86 PTI code testing and back-porting. ]
The KASAN shadow is currently mapped using vmemmap_populate() since that
provides a semi-convenient way to map pages into init_top_pgt. However,
since that no longer zeroes the mapped pages, it is not suitable for
KASAN, which requires zeroed shadow memory.
Add kasan_populate_shadow() interface and use it instead of
vmemmap_populate(). Besides, this allows us to take advantage of
gigantic pages and use them to populate the shadow, which should save us
some memory wasted on page tables and reduce TLB pressure.

a47ba4d77e12 ("perf/x86: Enable free running PEBS for REGS_USER/INTR")
... for easier x86 PTI code testing and back-porting. ]
Currently free running PEBS is disabled when user or interrupt
registers are requested. Most of the registers are actually
available in the PEBS record and can be supported.
So we just need to check for the supported registers and then
allow it: it is all except for the segment register.
For user registers this only works when the counter is limited
to ring 3 only, so this also needs to be checked.

If this feature is set, the FXSAVE, XSAVE, FXSAVEOPT, XSAVEC, XSAVES
/ FXRSTOR, XRSTOR, XRSTORS always save/restore error pointers,
thus making the X86_BUG_FXSAVE_LEAK workaround obsolete on such CPUs.

3522c2a6a4f3 ("x86/cpufeature: Add User-Mode Instruction Prevention definitions")
... for easier x86 PTI code testing and back-porting. ]
User-Mode Instruction Prevention is a security feature present in new
Intel processors that, when set, prevents the execution of a subset of
instructions if such instructions are executed in user mode (CPL > 0).
Attempting to execute such instructions causes a general protection
exception.
The subset of instructions comprises:
* SGDT - Store Global Descriptor Table
* SIDT - Store Interrupt Descriptor Table
* SLDT - Store Local Descriptor Table
* SMSW - Store Machine Status Word
* STR - Store Task Register
This feature is also added to the list of disabled-features to allow
a cleaner handling of build-time configuration.

timer_create() specifies via sigevent->sigev_notify the signal delivery for
the new timer. The valid modes are SIGEV_NONE, SIGEV_SIGNAL, SIGEV_THREAD
and (SIGEV_SIGNAL | SIGEV_THREAD_ID).
The sanity check in good_sigevent() is only checking the valid combination
for the SIGEV_THREAD_ID bit, i.e. SIGEV_SIGNAL, but if SIGEV_THREAD_ID is
not set it accepts any random value.
This has no real effects on the posix timer and signal delivery code, but
it affects show_timer() which handles the output of /proc/$PID/timers. That
function uses a string array to pretty print sigev_notify. The access to
that array has no bound checks, so random sigev_notify cause access beyond
the array bounds.
Add proper checks for the valid notify modes and remove the SIGEV_THREAD_ID
masking from various code pathes as SIGEV_NONE can never be set in
combination with SIGEV_THREAD_ID.

However, there are other error paths were the previously enabled
clocks are not disabled.
To fix the problem, fsl_disable_clocks() now takes the number of clocks
that shall be disabled + unprepared. For existing calls were all clocks
were already successfully prepared + enabled, DMAMUX_NR is passed to
disable + unprepare all clocks.
In error paths were only some clocks were successfully prepared +
enabled the loop counter is passed, in order to disable + unprepare
all successfully prepared + enabled clocks.

Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()")
introduced a bug (that is in fact documented by the patch commit text)
that leaves behind a dangling pointer. Since the done_wait structure is
allocated on the stack, future invocations to the DMATEST can produce
undesirable results (e.g., corrupted spinlocks).
Commit a9df21e34b42 ("dmaengine: dmatest: warn user when dma test times
out") attempted to WARN the user that the stack was likely corrupted but
did not fix the actual issue.
This patch fixes the issue by pushing the wait queue and callback
structs into the the thread structure. If a failure occurs due to time,
dmaengine_terminate_all will force the callback to safely call
wake_up_all() without possibility of using a freed pointer.

_xt_ is being dereferenced before it is null checked, hence there is a
potential null pointer dereference.
Fix this by moving the pointer dereference after _xt_ has been null
checked.

This adds a more specific Kconfig dependency to avoid the broken

Alternatively we could make CRAMFS itself depend on "MTD || !MTD" with a
similar result.

On a ppc64 machine, when mounting a fuzzed ext2 image (generated by
fsfuzzer) the following call trace is seen,
VFS: brelse: Trying to free free buffer
WARNING: CPU: 1 PID: 6913 at /root/repos/linux/fs/buffer.c:1165 .__brelse.part.6+0x24/0x40

This happens because the directory that ext4_find_entry() looks up has
inode->i_size that is less than the block size of the filesystem. This
causes 'nblocks' to have a value of zero. ext4_bread_batch() ends up not
reading any of the directory file's blocks. This renders the entries in
bh_use[] array to continue to have garbage data. buffer_uptodate() on
bh_use[0] can then return a zero value upon which brelse() function is
invoked.
This commit fixes the bug by returning -ENOENT when the directory file
has no associated blocks.

It's possible for ext4_get_acl() to return an ERR_PTR. So we need to
add a check for this case in __ext4_new_inode(). Otherwise on an
error we can end up oops the kernel.
This was getting triggered by xfstests generic/388, which is a test
which exercises the shutdown code path.

Currently, fallocate(2) with KEEP_SIZE followed by a fdatasync(2)
then crash, we'll see wrong allocated block number (stat -c %b), the
blocks allocated beyond EOF are all lost. fstests generic/468
exposes this bug.
Commit 67a7d5f561f4 ("ext4: fix fdatasync(2) after extent
manipulation operations") fixed all the other extent manipulation
operation paths such as hole punch, zero range, collapse range etc.,
but forgot the fallocate case.
So similarly, fix it by recording the correct journal tid in ext4
inode in fallocate(2) path, so that ext4_sync_file() will wait for
the right tid to be committed on fdatasync(2).
This addresses the test failure in xfstests test generic/468.

407cd7fb83c0 (ext4: change fast symlink test to not rely on i_blocks)
broke ~10 years old ext3 file systems created by 2.6.17. Any ELF
executable fails because the /lib/ld-linux.so.2 fast symlink
cannot be read anymore.
The patch assumed fast symlinks were created in a specific way,
but that's not true on these really old file systems.
The new behavior is apparently needed only with the large EA inode
feature.
Revert to the old behavior if the large EA inode feature is not set.
This makes my old VM boot again.

Only insert our special drain CQEs to support ib_drain_sq/rq() after
the wq is flushed. Otherwise, existing but not yet polled CQEs can be
returned out of order to the user application. This can happen when the
QP has exited RTS but not yet flushed the QP, which can happen during
a normal close (vs abortive close).
In addition never count the drain CQEs when determining how many CQEs
need to be synthesized during the flush operation. This latter issue
should never happen if the QP is properly flushed before inserting the
drain CQE, but I wanted to avoid corrupting the CQ state. So we handle
it and log a warning once.

In __flush_qp(), the CQ ARMED bit was being cleared regardless of
whether any notification is actually needed. This resulted in the iser
termination logic getting stuck in ib_drain_sq() because the CQ was not
marked ARMED and thus the drain CQE notification wasn't triggered.

The RDMA netlink core code checks validity of messages by ensuring
that type and operand are in range. It works well for almost all
clients except NLDEV, which has cb_table less than number of operands.
Request to access such operand will trigger the following kernel panic.
This patch updates all places where cb_table is declared for the
consistency, but only NLDEV is actually need it.

Mistakenly the driver didn't allow RSS hash fields combinations which
involve both IPv4 and IPv6 protocols. This bug caused to failures for
user's use cases for RSS.
Consequently, this patch fixes this bug and allows any combination that
the HW can support.
Additionally, the patch fixes the driver to return an error in case the
user provides an unsupported mask for RSS hash fields.

Per the infiniband spec an SMI MAD can have any PKey. Checking the pkey
on SMI MADs is not necessary, and it seems that some older adapters
using the mthca driver don't follow the convention of using the default
PKey, resulting in false denials, or errors querying the PKey cache.
SMI MAD security is still enforced, only agents allowed to manage the
subnet are able to receive or send SMI MADs.

The port number shift is still hard-coded to 1 while it now depends
on the hardware.
Thankfully 0 is always 0 no matter how you shift it, so this was a
bug without consequences.

The at24 driver creates dummy I2C devices to access offsets in the chip
that are outside the area supported using a single I2C address. It is not
meaningful to use runtime PM to such devices; the system firmware (ACPI)
does not know about these devices nor runtime PM was enabled for them.
Always use the real device instead of the dummy ones.
