This reverts commit a135a1b4c4.
This leads to blank screens on some boards after replugging a
display. Revert until we understand the root cause and can
fix both the leak and the blank screen after replug.

From Ard:
"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.
So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."
Disable support until the code can be properly refactored to support this
properly on aarch64.

This patch is to improve the fine grain tuning function for RV/RV2/PCO.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together. So this patch adds one flag to avoid this confusion, the flag
will make these two sysfs nodes work separately.
The flag is set as "disabled" by default, so the fine grain tuning function
will be disabled by default.
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag will be set as "enabled",
and the fine grain tuning function will be enabled.
In other profile modes, including "auto", "high", "low",
"profile_peak", "profile_standard", "profile_min_sclk",
"profile_min_mclk", the flag will be set as "disabled",
and the od range of fine grain tuning function will
be restored default value.

This patch is to improve the fine grain tuning function for RV/RV2/PCO.
This patch adds two new commands: "restore" and "commit".
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency manually or restore the default value.
Command guide:
echo "s level value" > pp_od_clk_voltage
"s" - set the sclk frequency
"level" - 0 or 1, "0" represents the min value, "1" represents
the max value
"value" - the target value of sclk frequency, it should be limited in the
safe range
echo "r" > pp_od_clk_voltage
"r" - reset the sclk frequency, restore the default value instantly
echo "c" > pp_od_clk_voltage
"c" - commit the min and max value of sclk frequency to the system
only after the commit command, the target values set by "s" command
will take effect.
Example:
1)change power profile from "auto" to "manual"
$ cat power_dpm_force_performance_level
auto
$ echo "manual" > power_dpm_force_performance_level
$ cat power_dpm_force_performance_level
manual
2)check the default sclk frequency
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
3)use "s" -- set command to configure the min and max sclk frequency
$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 600Mhz
1: 1000Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
4)use "r" -- reset command to restore the min or max sclk frequency
$ echo "r" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz

BXT/APL has different isr/irr/hpd regs compared with other GEN9. If not
setting these regs bits correctly according to the emulated monitor
(currently a DP on PORT_B), although gvt still triggers a virtual HPD
event, the guest driver won't detect a valid HPD pulse thus no full
display detection will be executed to read the updated EDID.
With this patch, the vfio_edid is enabled again on BXT/APL, which is

KASAN found this problem. find_first_bit() expects to look at a
pointer pointing to a long, but we look at a u32 - this is going to be
an issue with endianness but, KSAN already flags this as out-of-bounds
stack reads. This fixes it by just importing inot a local long.

then proceeeds to use that NULL pointer to compare memory content there
agains the new state to see if it changed. In this case, it's better to
assume that the input changed as there is no old state to compare
against and thus assume the changes happen anyway.

When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.
However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.
commit 48ea1e32c3 ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.

Commit 991fcb77f4 ("drm/edid: Fix uninitialized variable in
drm_cvt_modes()") just replaced one warning with another.
The original warning about a possibly uninitialized variable was due to
the compiler not being smart enough to see that the case statement
actually enumerated all possible cases. And the initial fix was just to
add a "default" case that had a single "unreachable()", just to tell the
compiler that that situation cannot happen.
However, that doesn't actually fix the fundamental reason for the
problem: the compiler still doesn't see that the existing case
statements enumerate all possibilities, so the compiler will still
generate code to jump to that unreachable case statement. It just won't
complain about an uninitialized variable any more.
So now the compiler generates code to our inline asm marker that we told
it would not fall through, and end end result is basically random. We
have created a bridge to nowhere.
And then, depending on the random details of just exactly what the
compiler ends up doing, 'objtool' might end up complaining about the
conditional branches (for conditions that cannot happen, and that thus
will never be taken - but if the compiler was not smart enough to figure
that out, we can't expect objtool to do so) going off in the weeds.
So depending on how the compiler has laid out the result, you might see
something like this:
drivers/gpu/drm/drm_edid.o: warning: objtool: do_cvt_mode() falls through to next function drm_mode_detailed.isra.0()
and now you have a truly inscrutable warning that makes no sense at all
unless you start looking at whatever random code the compiler happened
to generate for our bare "unreachable()" statement.
IOW, don't use "unreachable()" unless you have an _active_ operation
that generates code that actually makes it obvious that something is not
reachable (ie an UD instruction or similar).
Solve the "compiler isn't smart enough" problem by just marking one of
the cases as "default", so that even when the compiler doesn't otherwise
see that we've enumerated all cases, the compiler will feel happy and
safe about there always being a valid case that initializes the 'width'
variable.
This also generates better code, since now the compiler doesn't generate
comparisons for five different possibilities (the four real ones and the
one that can't happen), but just for the three real ones and "the rest"
(which is that last one).
A smart enough compiler that sees that we cover all the cases won't care.

There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control

- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660

- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for

Renesas, and Xilinx SoCs.

Some old ASICs might not implement/require get_dig_frontend helper; in
this scenario, we can have a NULL pointer exception when we try to call
it inside vbios disable operation. For example, this situation might
happen when using Polaris12 with an eDP panel. This commit avoids this
situation by adding a specific get_dig_frontend implementation for DCEx.

Merge misc updates from Andrew Morton:
- a few random little subsystems
- almost all of the MM patches which are staged ahead of linux-next
material. I'll trickle to post-linux-next work in as the dependents
get merged up.
Subsystems affected by this patch series: kthread, kbuild, ide, ntfs,
ocfs2, arch, and mm (slab-generic, slab, slub, dax, debug, pagecache,
gup, swap, shmem, memcg, pagemap, mremap, hmm, vmalloc, documentation,
kasan, pagealloc, memory-failure, hugetlb, vmscan, z3fold, compaction,
oom-kill, migration, cma, page-poison, userfaultfd, zswap, zsmalloc,
uaccess, zram, and cleanups).

mm: cleanup kstrto*() usage
mm: fix fall-through warnings for Clang
mm: slub: convert sysfs sprintf family to sysfs_emit/sysfs_emit_at
mm: shmem: convert shmem_enabled_show to use sysfs_emit_at
mm:backing-dev: use sysfs_emit in macro defining functions
mm: huge_memory: convert remaining use of sprintf to sysfs_emit and neatening
mm: use sysfs_emit for struct kobject * uses
mm: fix kernel-doc markups
zram: break the strict dependency from lzo
zram: add stat to gather incompressible pages since zram set up
zram: support page writeback

We need to move the check under the non-headless case, otherwise
we always reserve the VGA save size.

In Virtualization case, when one VF is sending too many
FLR requests, hypervisor would stop responding to this
VF's request for a long period of time. This is called
event guard. During this period of cooling time, guest
driver should wait instead of doing other things. After
this period of time, guest driver would resume reset
process and return to normal.
Currently, guest driver would wait 12 seconds and return fail
if it doesn't get response from host.
Solution: extend this waiting time in guest driver and poll
response periodically. Poll happens every 6 seconds and it will
last for 60 seconds.
v2: change the max repetition times from number to macro.

[Why]
The OGAM LUT precision was accumulating too much error
in the higher end.
[How]
Instead of calculating all points of the LUT in relation
to the previous ones, perform a full calculation in one
of the intermediate segments to stop error propagation.
