A variety of Lenovo machines with Rembrandt APUs and OLED panels have
stopped showing the display at login. This behavior clears up after
leaving it idle and moving the mouse or touching keyboard.
It was bisected to be caused by commit 559e265522 ("drm/amd/display:
keep eDP Vdd on when eDP stream is already enabled"). Revert this commit
to fix the issue.

Certain GL unit tests for large textures can cause problems
with the OOM killer since there is no way to link this memory
to a process. This was originally mitigated (but not necessarily
eliminated) by limiting the GTT size. The problem is this limit
is often too low for many modern games so just make the limit 1/2
of system memory. The OOM accounting needs to be addressed, but
we shouldn't prevent common 3D applications from being usable
just to potentially mitigate that corner case.
Set default GTT size to max(3G, 1/2 of system ram) by default.
v2: drop previous logic and default to 3/4 of ram
v3: default to half of ram to align with ttm
v4: fix spelling in comment (Kent)

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged
here for calculating the size of the destination buffer (0x10 instead of
0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with
the source and dest being struct fw_section_info_st, so the memcpy should
be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's
responsibility to figure out.
Avoid the whole thing and just do a direct assignment. This results in
no change to the executable code.
[This is a duplicate of commit 2c0ab32b73 ("hinic: Replace memcpy()

fix three such cases
- cache=loose or fscache was broken when trying to write a partial

ago. The fix taken here is just to restore old behavior of using the
special 'writeback_fid' for such reads, which is open as root/RDWR

Long-term it'd be nice to get rid of this and not issue the read at

This reverts commit 8fc74d1863.
BAR0 is the main (only?) register bank for this device. We most
obviously can't unmap it before the netdev is unregistered.
This was pointed out in review but the patch got reposted and
merged, anyway.
The author of the patch was only testing it with a QEMU model,
which I presume does not emulate enough for the netdev to be brought
up (author's replies are not visible in lore because they kept sending

The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call.
Complicating things, however, is that POWER8 systems need some per-cpu
state and kmalloc, which isn't available at this stage. So we split
things up into an early phase and a later opportunistic phase. This
commit also removes some noisy log messages that don't add much.

Simon reports that if two LAN9514 USB adapters are directly connected
without an intermediate switch, the link fails to come up and link LEDs
remain dark. The issue was introduced by commit 1ce8b37241 ("usbnet:
smsc95xx: Forward PHY interrupts to PHY driver to avoid polling").
The PHY suffers from a known erratum wherein link detection becomes
unreliable if Energy Detect Power-Down is used. In poll mode, the
driver works around the erratum by briefly disabling EDPD for 640 msec
to detect a neighbor, then re-enabling it to save power.
In interrupt mode, no interrupt is signaled if EDPD is used by both link
partners, so it must not be enabled at all.
We'll recoup the power savings by enabling SUSPEND1 mode on affected
LAN95xx chips in a forthcoming commit.

[Why&How]
GCC 12 catches the following incorrect comparison in the if arm
drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml/dcn32/display_mode_vba_32.c: In function ‘dml32_ModeSupportAndSystemConfigurationFull’:
drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml/dcn32/display_mode_vba_32.c:3740:33: error: the comparison will always evaluate as ‘true’ for the address of ‘USRRetrainingSupport’ will never be NULL [-Werror=address]

Fix this by remove preceding & so that value is compared instead of
address

[Why&How]
When the a 3d array is used by indexing with only one dimension in an if
condition, the addresses get compared instead of the intended value stored in the
array. GCC 12.1 caught this error:
drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml/dcn32/display_mode_vba_32.c: In function ‘DISPCLKDPPCLKDCFCLKDeepSleepPrefetchParametersWatermarksAndPerformanceCalculation’:

Fix this by explicitly specifying the last two indices.

Use the correct adev variable for the drm_fb_helper in
amdgpu_device_gpu_recover(). Noticed by inspection.

The DRM_RADEON Kconfig code contains:
select BACKLIGHT_CLASS_DEVICE
So the condition these ifdefs test for is always true, drop them.

For DCN20 and above, the code that actually hooks up the provided
input_color_space got lost at some point.
Fixes COLOR_ENCODING and COLOR_RANGE doing nothing on DCN20+.
Tested using Steam Remote Play Together + gamescope.
Update other DCNs the same wasy DCN1.x was updates in
