led on native i686.
Rename in_compat_syscall() to in_32bit_syscall() for x86-specific code
and make in_compat_syscall() false under !CONFIG_COMPAT.
With a following patch I'll clean generic users which were forced
to check IS_ENABLED(CONFIG_COMPAT) with in_compat_syscall().

Now that in_compat_syscall() == false on native i686, it's possible to
remove some ifdeffery and no more needed helpers.

for ipsec tunnels and to check
that kernel parses correctly the structures those differ in size.
It doesn't depend on any library and compat version can be easy
build with: make CFLAGS=-m32 net/ipsec

hes set according to critics and
separate compat xfrm layer. I've already a selftest to check that 32/64
bit xfrm works - so the most time-taking part is done.
So, if you'll wait a week or two - you may help me to justify acception
of mainstreaming those patches.
