e1791dae6c md/md-bitmap: pass in mddev directly for md_bitmap_resize()
And move the condition "if (mddev->bitmap)" into md_bitmap_resize() as
well, on the one hand make code cleaner, on the other hand try not to
access bitmap directly.

Since we are here, also change the parameter 'init' from int to bool.

48eb95810a md/md-bitmap: merge md_bitmap_unplug_async() into md_bitmap_unplug()
Add a parameter 'bool sync' to distinguish them, and
md_bitmap_unplug_async() won't be exported anymore, hence
bitmap_operations only need one op to cover them.

014125c64d drm/xe: Support 'nomodeset' kernel command-line option
Setting 'nomodeset' on the kernel command line disables all graphics
drivers with modesetting capabilities, leaving only firmware drivers,
such as simpledrm or efifb.

Most DRM drivers automatically support 'nomodeset' via DRM's module
helper macros. In xe, which uses regular module_init(), manually call
drm_firmware_drivers_only() to test for 'nomodeset'. Do not register
the driver if set.

v2:
- use xe's init table (Lucas)
- do NULL test for init/exit functions

01cc7b2e8a Revert "drm/panel-edp: Add SDC ATNA45AF01"
This reverts commit 8ebb1fc2e6.

The panel should be handled through the samsung-atna33xc20 driver for
correct power up timings. Otherwise the backlight does not work correctly.

We have existing users of this panel through the generic "edp-panel"
compatible (e.g. the Qualcomm X1E80100 CRD), but the screen works only
partially in that configuration: It works after boot but once the screen
gets disabled it does not turn on again until after reboot. It behaves the
same way with the default "conservative" timings, so we might as well drop
the configuration from the panel-edp driver. That way, users with old DTBs
will get a warning and can move to the new driver.

fc953d40bd clk: scmi: add is_prepared hook
Some clocks maybe default enabled by hardware. For clocks that don't
have users, that will be left in hardware default state, because prepare
count and enable count is zero,if there is no is_prepared hook to get
the hardware state. So add is_prepared hook to detect the hardware
state. Then when disabling the unused clocks, they can be simply
turned OFF to save power during kernel boot.

61aa894e7a nvme-pci: Add sleep quirk for Samsung 990 Evo
On some TUXEDO platforms, a Samsung 990 Evo NVMe leads to a high
power consumption in s2idle sleep (2-3 watts).

This patch applies 'Force No Simple Suspend' quirk to achieve a
sleep with a lower power consumption, typically around 0.5 watts.

a84dd0d8ae s390/ftrace: Avoid calling unwinder in ftrace_return_address()
ftrace_return_address() is called extremely often from
performance-critical code paths when debugging features like
CONFIG_TRACE_IRQFLAGS are enabled. For example, with debug_defconfig,
ftrace selftests on my LPAR currently execute ftrace_return_address()
as follows:

ftrace_return_address(0) - 0 times (common code uses __builtin_return_address(0) instead)
ftrace_return_address(1) - 2,986,805,401 times (with this patch applied)
ftrace_return_address(2) - 140 times
ftrace_return_address(>2) - 0 times

The use of __builtin_return_address(n) was replaced by return_address()
with an unwinder call by commit cae74ba8c2 ("s390/ftrace:
Use unwinder instead of __builtin_return_address()") because
__builtin_return_address(n) simply walks the stack backchain and doesn't
check for reaching the stack top. For shallow stacks with fewer than
"n" frames, this results in reads at low addresses and random
memory accesses.

While calling the fully functional unwinder "works", it is very slow
for this purpose. Moreover, potentially following stack switches and
walking past IRQ context is simply wrong thing to do for
ftrace_return_address().

Reimplement return_address() to essentially be __builtin_return_address(n)
with checks for reaching the stack top. Since the ftrace_return_address(n)
argument is always a constant, keep the implementation in the header,
allowing both GCC and Clang to unroll the loop and optimize it to the
bare minimum.

Fixes: cae74ba8c2 ("s390/ftrace: Use unwinder instead of __builtin_return_address()")

57216cc985 s390/build: Avoid relocation information in final vmlinux
Since commit 778666df60 ("s390: compile relocatable kernel without
-fPIE") the kernel vmlinux ELF file is linked with --emit-relocs to
preserve all relocations, so that all absolute relocations can be
extracted using the 'relocs' tool to adjust them during boot.

Port and adapt Petr Pavlu's x86 commit 9d9173e9ce ("x86/build: Avoid
relocation information in final vmlinux") to s390 to strip all
relocations from the final vmlinux ELF file to optimize its size.
Following is his original commit message with minor adaptions for s390:

The Linux build process on s390 roughly consists of compiling all input
files, statically linking them into a vmlinux ELF file, and then taking
and turning this file into an actual bzImage bootable file.

vmlinux has in this process two main purposes:
1) It is an intermediate build target on the way to produce the final
   bootable image.
2) It is a file that is expected to be used by debuggers and standard
   ELF tooling to work with the built kernel.

For the second purpose, a vmlinux file is typically collected by various
package build recipes, such as distribution spec files, including the
kernel's own tar-pkg target.

When building the kernel vmlinux contains also relocation information
produced by using the --emit-relocs linker option. This is utilized by
subsequent build steps to create relocs.S and produce a relocatable
image. However, the information is not needed by debuggers and other
standard ELF tooling.

The issue is then that the collected vmlinux file and hence distribution
packages end up unnecessarily large because of this extra data. The
following is a size comparison of vmlinux v6.10 with and without the
relocation information:

  | Configuration      | With relocs | Stripped relocs |
  | defconfig          |      696 MB |          320 MB |
  | -CONFIG_DEBUG_INFO |       48 MB |           32 MB |

Optimize a resulting vmlinux by adding a postlink step that splits the
relocation information into relocs.S and then strips it from the vmlinux
binary.

ca082333b4 clk: qcom: gcc-x1e80100: Don't use parking clk_ops for QUPs
Per Stephen Boyd's explanation in the link below, QUP RCG clocks do not
need to be parked when switching frequency. A side-effect in parking to a
lower frequency can be a momentary invalid clock driven on an in-use serial
peripheral.

This can cause "junk" to spewed out of a UART as a low-impact example. On
the x1e80100-crd this serial port junk can be observed on linux-next.

Apply a similar fix to the x1e80100 Global Clock controller to remediate.

We definitely could do with one less. Given that undef_access() is

latter loses the battle and is immediately sacrificed.

We also have a large number of instances where undef_access() is

5739a961b5 KVM: arm64: Force SRE traps when SRE access is not enabled
We so far only write the ICH_HCR_EL2 config in two situations:

- when we need to emulate the GICv3 CPU interface due to HW bugs

- when we do direct injection, as the virtual CPU interface needs
  to be enabled

This is all good. But it also means that we don't do anything special
when we emulate a GICv2, or that there is no GIC at all.

What happens in this case when the guest uses the GICv3 system
registers? The *guest* gets a trap for a sysreg access (EC=0x18)
while we'd really like it to get an UNDEF.

Fixing this is a bit involved:

- we need to set all the required trap bits (TC, TALL0, TALL1, TDIR)

- for these traps to take effect, we need to (counter-intuitively)
  set ICC_SRE_EL1.SRE to 1 so that the above traps take priority.

Note that doesn't fully work when GICv2 emulation is enabled, as
we cannot set ICC_SRE_EL1.SRE to 1 (it breaks Group0 delivery as
IRQ).

077b18abde md/md-bitmap: merge md_bitmap_close_sync() into bitmap_operations
So that the implementation won't be exposed, and it'll be possible
to invent a new bitmap by replacing bitmap_operations.

Also change the parameter from bitmap to mddev, to avoid access
bitmap outside md-bitmap.c as much as possible.

9be669bd1b md/md-bitmap: remove the parameter 'aborted' for md_bitmap_end_sync()
For internal callers, aborted are always set to false, while for
external callers, aborted are always set to true.

Hence there is no need to always pass in true for exported api.
