This change adds a test for libbpf_bpf_prog_type_str. The test retrieves
all variants of the bpf_prog_type enumeration using BTF and makes sure
that the function under test works as expected for them.

Add support for riscv jit to provide bpf_line_info. We need to
consider the prologue offset in ctx->offset, but unlike x86 and
arm64, ctx->offset of riscv does not provide an extra slot for
the prologue, so here we just calculate the len of prologue and
add it to ctx->offset at the end. Both RV64 and RV32 have been
tested.

We found that 32-bit environment can not print BPF line info due to a data
inconsistency between jited_ksyms[0] and jited_linfo[0].
For example:
jited_kyms[0] = 0xb800067c, jited_linfo[0] = 0xffffffffb800067c
We know that both of them store BPF func address, but due to the different
data extension operations when extended to u64, they may not be the same.
We need to unify the data extension operations of them.

This error happens because LLVM's integrated assembler has a one-pass
design, which means it cannot figure out the instruction lengths when
the .org directive is outside of the subsection that contains the
instructions, which was changed by the .option directives added by the
above change.
Move the .org directives before the .previous directive so that these
directives are always within the same subsection, which resolves the
failures and does not introduce any new issues with GNU as. This was
done for arm64 in commit 966a0acce2 ("arm64/alternatives: move length
validation inside the subsection") and commit 22315a2296 ("arm64:
alternatives: Move length validation in alternative_{insn, endif}").
While there is no error from the assembly versions of the macro, they
appear to have the same problem so just make the same change there as
well so that there are no problems in the future.

While it works, for the most part, to assume that the panel has
finished probing when devm_of_dp_aux_populate_ep_devices() returns,
it's a bit fragile. This is talked about at length in commit
a1e3667a98 ("drm/bridge: ti-sn65dsi86: Promote the AUX channel to
its own sub-dev").
When reviewing the ps8640 code, I managed to convince myself that it
was OK not to worry about it there and that maybe it wasn't really
_that_ fragile. However, it turns out that it really is. Simply
hardcoding panel_edp_probe() to return -EPROBE_DEFER was enough to put
the boot process into an infinite loop. I believe this manages to trip
the same issues that we used to trip with the main MSM code where
something about our actions trigger Linux to re-probe previously
deferred devices right away and each time we try again we re-trigger
Linux to re-probe.
Let's fix this using the callback introduced in the patch ("drm/dp:
Callbacks to make it easier for drivers to use DP AUX bus properly").
When using the new callback, we have to be a little careful. The
probe_done() callback is no longer always called in the context of
our probe routine. That means we can't rely on being able to return
-EPROBE_DEFER from it. We re-jigger the order of things a bit to
account for that.
With this change, the device still boots (though obviously the panel
doesn't come up) if I force panel-edp to always return
-EPROBE_DEFER. If I fake it and make the panel probe exactly once it
also works.

This adds a devm managed version of drm_bridge_add(). Like other
"devm" function listed in drm_bridge.h, this function takes an
explicit "dev" to use for the lifetime management. A few notes:
* In general we have a "struct device" for bridges that makes a good
candidate for where the lifetime matches exactly what we want.
* The "bridge->dev->dev" device appears to be the encoder
device. That's not the right device to use for lifetime management.

As talked about in this patch in the kerneldoc of
of_dp_aux_populate_ep_device() and also in the past in commit
a1e3667a98 ("drm/bridge: ti-sn65dsi86: Promote the AUX channel to
its own sub-dev"), it can be difficult for eDP controller drivers to
know when the panel has finished probing when they're using
of_dp_aux_populate_ep_devices().
The ti-sn65dsi86 driver managed to solve this because it was already
broken up into a bunch of sub-drivers. That means we could solve the
problem there by adding a new sub-driver to get the panel. We could
use the traditional -EPROBE_DEFER retry mechansim to handle the case
where the panel hadn't probed yet.
In parade-ps8640 we didn't really solve this. The code just expects
the panel to be ready right away. While reviewing the code originally
I had managed to convince myself it was fine to just expect the panel
right away, but additional testing has shown that not to be the
case. We could fix parade-ps8640 like we did ti-sn65dsi86 but it's
pretty cumbersome (since we're not already broken into multiple
drivers) and requires a bunch of boilerplate code.
After discussion [1] it seems like the best solution for most people
is:
- Accept that there's always at most one device that will probe as a
result of the DP AUX bus (it may have sub-devices, but there will be
one device _directly_ probed).
- When that device finishes probing, we can just have a call back.
This patch implements that idea. We'll now take a callback as an
argument to the populate function. To make this easier to land in
pieces, we'll make wrappers for the old functions. The functions with
the new name (which make it clear that we only have one child) will
take the callback and the functions with the old name will temporarily
wrap.

Commit cfc1d27789 ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.
This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.
So, set the prefix back to "module.".

When the system runs out of enclave memory, SGX can reclaim EPC pages
by swapping to normal RAM. These backing pages are allocated via a
per-enclave shared memory area. Since SGX allows unlimited over
commit on EPC memory, the reclaimer thread can allocate a large
number of backing RAM pages in response to EPC memory pressure.
When the shared memory backing RAM allocation occurs during
the reclaimer thread context, the shared memory is charged to
the root memory control group, and the shmem usage of the enclave
is not properly accounted for, making cgroups ineffective at
limiting the amount of RAM an enclave can consume.
For example, when using a cgroup to launch a set of test
enclaves, the kernel does not properly account for 50% - 75% of
shmem page allocations on average. In the worst case, when
nearly all allocations occur during the reclaimer thread, the
kernel accounts less than a percent of the amount of shmem used
by the enclave's cgroup to the correct cgroup.
SGX stores a list of mm_structs that are associated with
an enclave. Pick one of them during reclaim and charge that
mm's memcg with the shmem allocation. The one that gets picked
is arbitrary, but this list almost always only has one mm. The
cases where there is more than one mm with different memcg's
are not worth considering.
Create a new function - sgx_encl_alloc_backing(). This function
is used whenever a new backing storage page needs to be
allocated. Previously the same function was used for page
allocation as well as retrieving a previously allocated page.
Prior to backing page allocation, if there is a mm_struct associated
with the enclave that is requesting the allocation, it is set
as the active memory control group.

A recent regression in af_packet needed a preliminary debug patch,

The af_packet fix is to make sure MAC headers are contained in

I have a board where these two lines are always printed during boot:
imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.
While here, add the missing \n to one of the format strings.

Our internal teams have identified a few additional engine registers
that are worth inspecting in error state dumps during development &
debug. Let's capture and print them as part of our error dump.
For simplicity we'll just dump these registers on gen11 and beyond.
Most of these registers have existed since earlier platforms (e.g., gen6
or gen7) but were initially introduced only for a subset of the
platforms' engines; gen11 seems to be where they became available on all
engines.

The {pid,uid}_t fields of struct binder_transaction were recently
replaced to use kernel types in commit 169adc2b6b ("android/binder.h:
add linux/android/binder(fs).h to UAPI compile-test coverage").
However, using __kernel_uid_t here breaks backwards compatibility in
architectures using 16-bits for this type, since glibc and some others
still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which
avoids this compatibility problem.

The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.
The Apple PCIe host schema is missing 'power-domains' in the schema.
The example has 3 power domains. However, this is wrong too as actual
dts files have a single power domain and Sven confirmed 1 is correct.

The default mapping of ASPRX1 (DAC source) is slot 0. Change the slot
mapping of right amplifiers (WR and TR) to slot 1 to receive right
channel data. Also update the ACPI instance ID mapping according to HW
configuration.

PVC splits the mask of enabled DSS over two registers. It also changes
the meaning of the EU fuse register such that each bit represents a
single EU rather than a pair of EUs.

As with EU masks, it's easier to store subslice/DSS masks internally in
a format that's more natural for the driver to work with, and then only
covert into the u8[] uapi form when the query ioctl is invoked. Since
the hardware design changed significantly with Xe_HP, we'll use a union
to choose between the old "hsw-style" subslice masks or the newer xehp
mask. HSW-style masks will be stored in an array of u8's, indexed by
slice (there's never more than 6 subslices per slice on older
platforms). For Xe_HP and beyond where slices no longer exist, we only
need a single bitmask. However we already know that this mask is
eventually going to grow too large for a simple u64 to hold, so we'll
represent it in a manner that can be operated on by the utilities in
linux/bitmap.h.
v2:
- Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status()
v3:
- Eliminate sseu->ss_stride and just calculate the stride while
specifically handling uapi. (Tvrtko)
- Use BITMAP_BITS() macro to refer to size of masks rather than
passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko)
- Report compute/geometry DSS masks separately when dumping Xe_HP SSEU
info. (Tvrtko)
- Restore dropped range checks to intel_sseu_has_subslice(). (Tvrtko)
v4:
- Make the bitmap size macro check the size of the .xehp field rather
than the containing union. (Tvrtko)
- Don't add GEM_BUG_ON() intel_sseu_has_subslice()'s check for whether
slice or subslice ID exceed sseu->max_[sub]slices; various loops
in the driver are expected to exceed these, so we should just
silently return 'false.'
v5:
- Move XEHP_BITMAP_BITS() to the header so that we can also replace a
usage of I915_MAX_SS_FUSE_BITS in one of the inline functions.
(Bala)
- Change the local variable in intel_slicemask_from_xehp_dssmask() from
u16 to 'unsigned long' to make it a bit more future-proof.
