Subject: [PATCH] scripts/update-linux-headers: Add setup_data.h to import list

Data structures like struct setup_data have been moved to a separate
setup_data.h header which bootparam.h relies on. Add setup_data.h to
the cp_portable() list and sync it along with the other header files.

Note that currently struct setup_data is stripped away as part of
generating bootparam.h, but that handling is no currently needed for
setup_data.h since it doesn't pull in many external
headers/dependencies. However, QEMU currently redefines struct
setup_data in hw/i386/x86.c, so that will need to be removed as part of
any header update that pulls in the new setup_data.h to avoid build
bisect breakage.

Because <asm/setup_data.h> is the first architecture specific #include
in include/standard-headers/, add a new sed substitution to rewrite
asm/ include to the standard-headers/asm-* subdirectory for the current
architecture.

And while at it, remove asm-generic/kvm_para.h from the list of
allowed includes: it does not have a matching substitution, and therefore
it would not be possible to use it on non-Linux systems where there is
no /usr/include/asm-generic/ directory.
