This was causing a "sleeping function called from invalid context"
warning.
I don't think we need the set_and_test_bit() here; clients move from
unconfirmed to confirmed only once, under the client_lock.
The (conf == unconf) is a way to check whether we're in that confirming
case, hopefully that's not too obscure.

pipeline stall
This patch will reduce cpu usage dramatically in kernel space especially
for application which use sys-call with large buffer size, such as
network applications. The main reason behind this is that every
unaligned memory access will raise exceptions and switch between s-mode
and m-mode causing large overhead.
First copy in bytes until reaches the first word aligned boundary in
destination memory address. This is the preparation before the bulk
aligned word copy.
The destination address is aligned now, but oftentimes the source
address is not in an aligned boundary. To reduce the unaligned memory
access, it reads the data from source in aligned boundaries, which will
cause the data to have an offset, and then combines the data in the next
iteration by fixing offset with shifting before writing to destination.
The majority of the improving copy speed comes from this shift copy.
In the lucky situation that the both source and destination address are
on the aligned boundary, perform load and store with register size to
copy the data. Without the unrolling, it will reduce the speed since the
next store instruction for the same register using from the load will
stall the pipeline.
At last, copying the remainder in one byte at a time.

In preparation to enable -Wimplicit-fallthrough for Clang, fix a
warning by explicitly adding a fallthrough; statement.
Notice that this seems to be a Duff device for performance[1]. So,
although the code looks a bit _funny_, I didn't want to refactor
or modify it beyond merely adding a fallthrough marking, which
might be the least disruptive way to fix this issue.

This patch adds stack overflow detection to riscv, usable when
CONFIG_VMAP_STACK=y.
Overflow is detected in kernel exception entry(kernel/entry.S), if the
kernel stack is overflow and been detected, the overflow handler is
invoked on a per-cpu overflow stack. This approach preserves GPRs and
the original exception information.
The overflow detect is performed before any attempt is made to access
the stack and the principle of stack overflow detection: kernel stacks
are aligned to double their size, enabling overflow to be detected with
a single bit test. For example, a 16K stack is aligned to 32K, ensuring
that bit 14 of the SP must be zero. On an overflow (or underflow), this
bit is flipped. Thus, overflow (of less than the size of the stack) can
be detected by testing whether this bit is set.
This gives us a useful error message on stack overflow, as can be
trigger with the LKDTM overflow test:

The code in xcs_resume() probably didn't work as intended. It uses
struct drm_device.irq, which is allocated to 0, but never initialized
by i915 to the device's interrupt number.
Change all calls to synchronize_hardirq() to intel_synchronize_irq(),
which uses the correct interrupt. _hardirq() functions are not needed
in this context.
v5:
* go back to _hardirq() after PCI probe reported wrong
context; add rsp comment
v4:
* switch everything to intel_synchronize_irq() (Daniel)
v3:
* also use intel_synchronize_hardirq() at another callsite
v2:
* wrap irq code in intel_synchronize_hardirq() (Ville)

_DG1_DPCLKA0_CFGCR0 maps between DPLL 0 and 1 with one bit for phy A
and B while _DG1_DPCLKA1_CFGCR0 maps between DPLL 2 and 3 with one
bit for phy C and D.
Reusing _cnl_ddi_get_pll() don't take that into cosideration returing
DPLL 0 and 1 for phy C and D.
That is a regression introduced in the refactor done in
commit 351221ffc5e5 ("drm/i915: Move DDI clock readout to
encoder->get_config()").
While at it also dropping the macros previously used, not reusing it
