This is offtopic, but I am wondering if something like the patch below
makes any sense.
It moves the common TIF_ flags into include/asm-generic/thread_info.h
Generated by this script:
#!/usr/bin/perl -w
use strict;
# the (probably incomplete) list of arches which have some bits
# hardcoded
my $SKIP = join '|', qw(c6x sparc);
# the (incomplete) list of "safe" flags which can be moved into
# asm-generic even if not supported
my @SAFE = qw(TIF_SECCOMP TIF_UPROBE);
my %tifs;
my @files = grep {
open my $fd, '<', $_ or die $_;
my $has; local $_;
/^\s*#define\s*(TIF_\w+)\s+\d+\b/ and $has = ++$tifs{$1}
while <$fd>;
$has;
} grep !m{^arch/($SKIP)/}o,
split "\n", qx(find arch/*/include/asm/thread_info*.h);
my %comm = map +($_,1), grep $tifs{$_} == @files, keys %tifs;
$comm{$_} = $tifs{$_} = 1 for @SAFE;
our $ctr;
my @comm = sort keys %comm;
print "--- /dev/null\n+++ x/include/asm-generic/thread_info.h\n";
print "@@ -0,0 +1,@{[2*@...m+3]} @@\n";
print "+#define $_\t@{[$ctr++]}\n" for @comm;
print "+\n+#define TIF__ARCH\t$ctr\n+\n";

sub patch
{
return $_ unless /^(\s*#define\s*)(_)?(TIF_\w+)/ and $tifs{$3};
return if $comm{$3}; return $_ if $2;
(!$ctr && "#include <asm-generic/thread_info.h>\n\n")

open my $fd, '<', $file or die;
open my $diff, "|diff -u --label=x/$file $file --label=x/$file -"
