Re: [PATCH 6.3 00/29] 6.3.11-rc1 review

Hello!

Early report of failures.

Arm64 fails with GCC-11 on the following configurations:
* lkftconfig
* lkftconfig-64k_page_size
* lkftconfig-debug
* lkftconfig-debug-kmemleak
* lkftconfig-kasan
* lkftconfig-kselftest
* lkftconfig-kunit
* lkftconfig-libgpiod
* lkftconfig-perf
* lkftconfig-rcutorture

lkftconfig is basically defconfig + a few fragments [1]. The suffixes
mean that we're enabling a few other kconfigs.

Failure:
-----8<-----
/builds/linux/arch/arm64/mm/fault.c: In function 'do_page_fault':
/builds/linux/arch/arm64/mm/fault.c:576:9: error: 'vma' undeclared
(first use in this function); did you mean 'vmap'?
576 | vma = lock_mm_and_find_vma(mm, addr, regs);

identifier is reported only once for each function it appears in

arch/arm64/mm/fault.o] Error 1
make[4]: Target 'arch/arm64/mm/' not remade because of errors.
----->8-----

We're expecting to see more failures on other architectures, and so
will follow-up with that.
