None of these functions are used, so remove them.
This renders the two bugs moot:
- get_random_u64_wait() used the wrong pointer type, making it provide
only 32 bits.
- The '#undef' directive used the wrong identifier, leaving the helper
macro defined.

Crystal reports that the PCIe Advanced Error Reporting driver gets stuck
in an infinite loop on PREEMPT_RT:
Both the primary interrupt handler aer_irq() as well as the secondary
handler aer_isr() are forced into threads with identical priority.
Crystal writes that on the ARM system in question, the primary handler
has to clear an error in the Root Error Status register...
"before the next error happens, or else the hardware will set the
Multiple ERR_COR Received bit. If that bit is set, then aer_isr()
can't rely on the Error Source Identification register, so it scans
through all devices looking for errors -- and for some reason, on
this system, accessing the AER registers (or any Config Space above
0x400, even though there are capabilities located there) generates
an Unsupported Request Error (but returns valid data). Since this
happens more than once, without aer_irq() preempting, it causes
another multi error and we get stuck in a loop."
The issue does not show on non-PREEMPT_RT because the primary handler
runs in hardirq context and thus can preempt the threaded secondary
handler, clear the Root Error Status register and prevent the secondary
handler from getting stuck.
Emulate the same behavior on PREEMPT_RT by assigning a lower default
priority to the secondary handler if the primary handler is forced into
a thread.

Add INIT_ERR_PTR() macro to initialize static variables with error
pointers. This might be useful for specific case where there is a static
variable initialized to an error condition and then later set to the
real handle once probe finish/completes.
This is to handle compilation problems like:
error: initializer element is not constant
where ERR_PTR() can't be used.

Phase-adjust values are currently limited by a min-max range. Some
hardware requires, for certain pin types, that values be multiples of
a specific granularity, as in the zl3073x driver.
Add a `phase-adjust-gran` pin attribute and an appropriate field in
dpll_pin_properties. If set by the driver, use its value to validate
user-provided phase-adjust values.

Handle the NIC hardware link state events received from the HW
channel, then set the proper link state accordingly.
And, add a feature bit, GDMA_DRV_CAP_FLAG_1_HW_VPORT_LINK_AWARE,
to inform the NIC hardware this handler exists.
Our MANA NIC only sends out the link state down/up messages
when we need to let the VM rerun DHCP client and change IP
address. So, add netif_carrier_on() in the probe(), let the NIC
show the right initial state in /sys/class/net/ethX/operstate.

Commit 378b7708194f ("sched: Make migrate_{en,dis}able() inline") made

there are four symbols for migrate_{enable,disable}:

Fix the issue by marking migrate_{enable,disable} as always inline.
The alternative is to mark them as notrace/nokprobe which is more

In the parse_adv_monitor_pattern() function, the value of
the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
The size of the 'value' array in the mgmt_adv_pattern structure is 31.
If the value of 'pattern[i].length' is set in the user space
and exceeds 31, the 'patterns[i].value' array can be accessed
out of bound when copied.
Increasing the size of the 'value' array in
the 'mgmt_adv_pattern' structure will break the userspace.
Considering this, and to avoid OOB access revert the limits for 'offset'
and 'length' back to the value of HCI_MAX_AD_LENGTH.

(linuxtesting.org) with SVACE.

For now, all the kernel functions who are hooked by the fprobe will be
added to the hash table "fprobe_ip_table". The key of it is the function
address, and the value of it is "struct fprobe_hlist_node".
The budget of the hash table is FPROBE_IP_TABLE_SIZE, which is 256. And
this means the overhead of the hash table lookup will grow linearly if
the count of the functions in the fprobe more than 256. When we try to
hook all the kernel functions, the overhead will be huge.
Therefore, replace the hash table with rhltable to reduce the overhead.

An ftrace warning was reported in ftrace_init_ool_stub():
WARNING: arch/powerpc/kernel/trace/ftrace.c:234 at ftrace_init_ool_stub+0x188/0x3f4, CPU#0: swapper/0
The problem is that the linker script is placing .text.startup in .text
rather than in .init.text, due to an inadvertent match of the TEXT_MAIN
'.text.[0-9a-zA-Z_]*' pattern.
This bug existed for some configurations before, but is only now coming
to light due to the TEXT_MAIN macro unification in commit 1ba9f8979426
("vmlinux.lds: Unify TEXT_MAIN, DATA_MAIN, and related macros").
The .text.startup section consists of constructors which are used by
KASAN, KCSAN, and GCOV. The constructors are only called during boot,
so .text.startup is supposed to match the INIT_TEXT pattern so it can be
placed in .init.text and freed after init. But since INIT_TEXT comes
*after* TEXT_MAIN in the linker script, TEXT_MAIN needs to manually
exclude .text.startup.
Update TEXT_MAIN to exclude .text.startup (and its .text.startup.*
variant from -ffunction-sections), along with .text.exit and
.text.exit.* which should match EXIT_TEXT.
Specifically, use a series of more specific glob patterns to match
generic .text.* sections (for -ffunction-sections) while explicitly
excluding .text.startup[.*] and .text.exit[.*].
Also update INIT_TEXT and EXIT_TEXT to explicitly match their
-ffunction-sections variants (.text.startup.* and .text.exit.*).

This patch introduces infrastructure for allocating req objects on the
stack for AEADs. The additions mirror the existing sync skcipher APIs.
This can be used in cases where simple sync AEAD operations are being
done. So allocating the request on stack avoides possible out-of-memory
errors.
The struct crypto_sync_aead is a wrapper around crypto_aead and should
be used in its place when sync only requests will be done on the stack.
Correspondingly, the request should be allocated with
SYNC_AEAD_REQUEST_ON_STACK().
Similar to sync_skcipher APIs, the new sync_aead APIs are wrappers
around the regular aead APIs to facilitate sync only operations. The
following crypto APIs are added:
- struct crypto_sync_aead
- crypto_alloc_sync_aead()
- crypto_free_sync_aead()
- crypto_aync_aead_tfm()
- crypto_sync_aead_setkey()
- crypto_sync_aead_setauthsize()
- crypto_sync_aead_authsize()
- crypto_sync_aead_maxauthsize()
- crypto_sync_aead_ivsize()
- crypto_sync_aead_blocksize()
- crypto_sync_aead_get_flags()
- crypto_sync_aead_set_flags()

GPUs typically benefit from contiguous memory via reduced TLB pressure and
improved caching performance, where the maximum size of contiguous block
which adds a performance benefit is related to hardware design.
TTM pool allocator by default tries (hard) to allocate up to the system
MAX_PAGE_ORDER blocks. This varies by the CPU platform and can also be
configured via Kconfig.
If that limit was set to be higher than the GPU can make an extra use of,
lets allow the individual drivers to let TTM know over which allocation
order can the pool allocator afford to make a little bit less effort with.
We implement this by disabling direct reclaim for those allocations, which
reduces the allocation latency and lowers the demands on the page

Drop the QPIC interconnect and BCM nodes for the SDX75 SoC. The reason
is that this QPIC BCM resource is already defined as a RPMh clock in
clk-rpmh driver as like other SDX SoCs. So it is wrong to describe the
same resource in two different providers.
Also, without this series, the NAND driver fails to probe on SDX75 as
the interconnect sync state disables the QPIC nodes as there were no
clients voting for this ICC resource. However, the NAND driver had already
voted for this BCM resource through the clk-rpmh driver. Since both votes
come from Linux, RPMh was unable to distinguish between these two and ends
up disabling the resource during sync state.

As like other SDX targets, SDX75 QPIC BCM resource is also modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect node mistakenly.
Hence, drop the QPIC interconnect IDs and let the clients use clk-rpmh
driver to vote for this resource.
Even though this change is an ABI break, it is necessary to avoid
describing the same resource provider in two different drivers, as it may
lead to votes from clients overriding each other.

Rename drm_client_framebuffer_create() to drm_client_buffer_create_dump()
and adapt callers. The new name reflects the function's purpose. Using
dumb buffers is the easiest way for creating a GEM buffer in a drivers-
independent way.
There's also drm_client_buffer_create(), which creates the client buffer
from a preexisting buffer object. This helper can be exported for drivers
that create their own GEM buffer object.

The client buffer's framebuffer holds a reference and pointer on
each of its GEM buffer objects. Thus the field gem in the client-
buffer struct is not necessary. Deprecated the field and convert
the client-buffer helpers to use the framebuffer's objects.
In drm_client_buffer_delete(), do a possible vunmap before releasing
the framebuffer. Otherwise we'd eventually release the framebuffer
before unmaping its buffer objects.

cgroup1 freezer piggybacks on the PM freezer, which inadvertently allowed
userspace to produce uninterruptible tasks at will. To avoid the issue,
cgroup2 freezer switched to a separate job control based mechanism. While
this happened a long time ago, the code and comment haven't been updated
making it confusing to people who aren't familiar with the history.
Rename cgroup_freezing() to cgroup1_freezing() and update comments on top of
freezing() and frozen() to clarify that cgroup2 freezer isn't covered by the
PM freezer mechanism.
