This series copies the files syscall.tbl from linux v5.5 and generates
the file syscall_nr.h from them.

This is done for all the QEMU targets that have a syscall.tbl
in the linux source tree: mips, mips64, i386, x86_64, sparc, s390x,
ppc, arm, microblaze, sh4, xtensa, m68k, hppa and alpha.

tilegx and cris are depecrated in linux (tilegx has no maintainer in QEMU)

aarch64, nios2, openrisc and riscv have no syscall.tbl in linux and files
are generated manually with the help of a script from the asm-generic/unistd.h

Define do_arch_prctl() with -TARGET_ENOSYS for i386 as the syscall number
is defined now.

I have also removed all syscalls in s390x/syscall_nr.h defined for
!defined(TARGET_S390X).

I have added a script to copy all these files from linux and updated
them at the end of the series with their latest version for today.

Two patches manage the special case for mips O32 that needs
to know the number of arguments. We find them in strace sources.

v3:
   Add a patch to define do_arch_prctl() for i386

v2:
    fix a typo (double comma) in $(call quiet-command)
    add a script to remove dependencies to syscall_nr.h in source directory

ppc, mips64:

        we don't need to split syscall_nr.h as it is generated
        according TARGET_SYSTBL_ABI to TARGET_ABI_DIR
        and generated values are incorrect according to the file name.

arm:

        manage TARGET_NR_arm_sync_file_range

Once the syscall_nr.h are built in the build directory, the following script
allows to compare them with the original one (first argument is the path
to build directory), it must be run from the source directory:

cat > check_syscall_nr.sh <<EOF
BUILD="$1"

ARCHS="i386 alpha arm hppa i386 m68k microblaze s390x sh4 sparc sparc64 xtensa ppc"

syscall_nr_diff()
{
        arch=$1
        target=$2
        syscall_nr=linux-user/$arch/syscall_nr.h
        offset=$3
        REFERENCE=$(git log -1 --format=format:%h -- $syscall_nr)^
        if [ "$offset" = "" ] ; then
                git show $REFERENCE:$syscall_nr | \
                        sed 's/[[:blank:]]\/\*[^*]*\*\///' | \
                        sed 's/(\([^)]*\))/\1/'  > /tmp/old
        else
                git show $REFERENCE:$syscall_nr | \
                        sed 's/[[:blank:]]\/\*[^*]*\*\///' | \
                        sed "s/TARGET_NR_Linux/$offset/" > /tmp/old
        fi
        diff -wu --color=always /tmp/old \
                                $BUILD/$target/$syscall_nr | less -R
}

for arch in $ARCHS ; do
        syscall_nr_diff $arch $arch-linux-user
done

syscall_nr_diff ppc    ppc64-linux-user

syscall_nr_diff mips   mips-linux-user    4000
syscall_nr_diff mips64 mips64-linux-user  5000
syscall_nr_diff mips64 mipsn32-linux-user 6000
