A new warning in clang points out a few places in this driver where a
bitwise OR is being used with boolean types:

drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]
        data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x",
                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This use of a bitwise OR is intentional, as bitwise operations do not
short circuit, which allows all the calls to touchscreen_get_prop_u32()
to happen so that the last parameter is initialized while coalescing the
results of the calls to make a decision after they are all evaluated.

To make this clearer to the compiler, use the '|=' operator to assign
the result of each touchscreen_get_prop_u32() call to data_present,
which keeps the meaning of the code the same but makes it obvious that
every one of these calls is expected to happen.

On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
associated clock. Accessing the registers requires that this clock is
enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
having the clock enabled results in a complete hang of the machine.
(This usually only happens if snvs_pwrkey is built as a module and the
rtc-snvs driver isn't already bound because at bootup the required clk
is on and only gets disabled when the clk framework disables unused clks
late during boot.)

This completes the fix in commit 135be16d

 ("ARM: dts: imx7s: add
snvs clock to pwrkey").

I received a build failure for a new patch I'm working on the nds32
architecture, and when I went to test it, I couldn't get to my build error,
because it failed to build with a bunch of:

  Error: invalid operands (*UND* and *UND* sections) for `^'

issues with various files. Those files were temporary asm files that looked
like:  kernel/.tmp_mc_fork.s

I decided to look deeper, and found that the "mc" portion of that name
stood for "mcount", and was created by the recordmcount.pl script. One that
I wrote over a decade ago. Once I knew the source of the problem, I was
able to investigate it further.

The way the recordmcount.pl script works (BTW, there's a C version that
simply modifies the ELF object) is by doing an "objdump" on the object
file. Looks for all the calls to "mcount", and creates an offset of those
locations from some global variable it can use (usually a global function
name, found with <.*>:). Creates a asm file that is a table of references
to these locations, using the found variable/function. Compiles it and
links it back into the original object file. This asm file is called
".tmp_mc_<object_base_name>.s".

The problem here is that the objdump produced by the nds32 object file,
contains things that look like:

 0000159a <.L3^B1>:
    159a:       c6 00           beqz38 $r6, 159a <.L3^B1>
                        159a: R_NDS32_9_PCREL_RELA      .text+0x159e
    159c:       84 d2           movi55 $r6, #-14
    159e:       80 06           mov55 $r0, $r6
    15a0:       ec 3c           addi10.sp #0x3c

Where ".L3^B1 is somehow selected as the "global" variable to index off of.

Then the assembly file that holds the mcount locations looks like this:

        .section __mcount_loc,"a",@progbits
        .align 2
        .long .L3^B1 + -5522
        .long .L3^B1 + -5384
        .long .L3^B1 + -5270
        .long .L3^B1 + -5098
        .long .L3^B1 + -4970
        .long .L3^B1 + -4758
        .long .L3^B1 + -4122
        [...]

And when it is compiled back to an object to link to the original object,
the compile fails on the "^" symbol.

Simple solution for now, is to have the perl script ignore using function
symbols that have an "^" in the name.

it finds in sigcontext.  Attacker can store whatever they want in there,
which includes things like S-bit.  Userland shouldn't be able to set

Do the same thing other architectures with protected bits in flags
register do - preserve everything that shouldn't be settable in

Commit 64f7c698 ("drm/nouveau/fifo: add engine_id hook") replaced
fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of
fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned
from the later g84_fifo_engine_id() are incremented by 1 compared to
the previous g84_fifo_chan_engine() return values.

This is fine either way for most of the code, except this one line
where an engine bit programmed into the hardware is derived from the
return value. Decrement the return value accordingly, otherwise the
wrong engine bit is programmed into the hardware and that leads to
the following failure:
nouveau 0000:01:00.0: gr: 00000030 [ILLEGAL_MTHD ILLEGAL_CLASS] ch 1 [003fbce000 DRM] subc 3 class 0000 mthd 085c data 00000420

Hyper-V supports a hardware cursor feature. It is not used by Linux VM,
but the Hyper-V host still draws a point as an extra mouse pointer,
which is unwanted, especially when Xorg is running.

The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer.
When the hyperv_drm driver was developed, the function synthvid_send_ptr()
was not copied from the hyperv_fb driver. Fix the issue by adding the
function into hyperv_drm.

In commit e11f5bd8 ("drm: Add support for DP 1.4 Compliance edid
corruption test") the function connector_bad_edid() started assuming
that the memory for the EDID passed to it was big enough to hold
`edid[0x7e] + 1` blocks of data (1 extra for the base block). It
completely ignored the fact that the function was passed `num_blocks`
which indicated how much memory had been allocated for the EDID.

Let's fix this by adding a bounds check.

This is important for handling the case where there's an error in the
first block of the EDID. In that case we will call
connector_bad_edid() without having re-allocated memory based on
`edid[0x7e]`.
