microblaze-linux-gcc (GCC) 9.3.0 complains about missing __ffssi2
symbol while using __builtin_ffs at runtime.
This is because arch/h8300 is compiled with -fno-builtin option.
so fallback and use kernel ffs() instead to all the arch builds happy!

EFI uses kernel_fpu_begin() to conform to the UEFI calling convention.
This specifically requires initializing FCW (FPU Control Word), whereas
no sane 64-bit kernel code should use legacy 387 operations that
reference FCW.
This should allow to safely change the default semantics of
kernel_fpu_begin() to stop initializing FCW on 64-bit kernels.

The VT-d IOMMU response RESPONSE_FAILURE for a page request in below
cases:
- When it gets a Page_Request with no PASID;
- When it gets a Page_Request with PASID that is not in use for this
device.
This is allowed by the spec, but IOMMU driver doesn't support such cases
today. When the device receives RESPONSE_FAILURE, it sends the device
state machine to HALT state. Now if we try to unload the driver, it hangs
since the device doesn't send any outbound transactions to host when the
driver is trying to clear things up. The only possible responses would be
for invalidation requests.
Let's use RESPONSE_INVALID instead for now, so that the device state
machine doesn't enter HALT state.

It is incorrect to always clear PRO when it's set w/o first checking
whether the overflow condition has been cleared. Current code assumes
that if an overflow condition occurs it must have been cleared by earlier
loop. However since the code runs in a threaded context, the overflow
condition could occur even after setting the head to the tail under some
extreme condition. To be sane, we should read both head/tail again when
seeing a pending PRO and only clear PRO after all pending PRs have been
handled.

Since 5d283b0838 ("clk: imx6: Fix procedure to switch the parent

from reset value on system boot. This warning is printed even if
the bootloader (or a previous kernel that did kexec) followed the
correct procedure for glitch-free reparenting.
As such systems are doing everything correctly, a warning is too
harsh. Demote to a notice, so users are still alerted, but without
cluttering a loglevel=5 boot.

The R-Car System Controller (SYSC) driver registers PM domains from an
early_initcall(). It does not use a platform driver, as secondary CPU
startup on R-Car H1 needs to control the CPU power domains, before
initialization of the driver framework.
As fw_devlink only considers devices, it does not know that the System
Controller is ready. Hence probing of on-chip devices that are part of
the SYSC PM domain fails if fw_devlink is enabled:
probe deferral - supplier e6180000.system-controller not ready
Fix this by setting the OF_POPULATED flag for the SYSC device node after
successful initialization. This will make of_link_to_phandle() ignore
the SYSC device node as a dependency, and consumer devices will be
probed again.
