df561f6688 treewide: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

3db07e70f0 x86, boot: Pass cmd_line_ptr with unsigned long instead
boot/compressed/misc.c is used for bzImage in 64bit and 32bit, and
cmd_line_ptr could point to buffer that is above 4g, cmd_line_ptr
should be 64bit otherwise high 32bit will be capped out.

So need to change data type to unsigned long, that will be 64bit get
correct address of command line buffer.

And it is still ok with 32bit bzImage, because unsigned long on 32bit kernel
is still 32bit.

16a4baa642 x86, boot: Move checking of cmd_line_ptr out of common path
cmdline.c::__cmdline_find_option... are shared between 16-bit setup code
and 32/64 bit decompressor code.

for 32/64 only path via kexec, we should not check if ptr is less 1M.
as those cmdline could be put above 1M, or even 4G.

Move out accessible checking out of __cmdline_find_option()
So decompressor in misc.c can parse cmdline correctly.

f4ed2877b1 x86, setup: reorganize the early console setup
Separate early_serial_console from tty.c

This allows for reuse of
early_serial_console.c/string.c/printf.c/cmdline.c in boot/compressed/.

-v2: according to hpa, don't include string.c etc
-v3: compressed/misc.c must have early_serial_base as static, so move it back to tty.c
     for setup code

32d0b98980 x86 setup: early cmdline parser handle boolean options
This patch extends the early commandline parser to support boolean options.
The current version in mainline only supports parsing "option=arg" value pairs.

With this it should be easy making other messages like "Uncompressing kernel"
honour the "quiet" parameter, too.
