Hi there, fb3739759474d150a9927b920a80ea2afb4c2a51 (from mainline) should be included in linux-4.19.y, if a589979f345720aca32ff43a2ccaa16a70871b9e stays in. **** ## Long version ## It looks like: ``` hpet: Support 32-bit userspace https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-4.19.y&id=a589979f345720aca32ff43a2ccaa16a70871b9e ``` ...breaks the non-HP-Sim ia64 build ([1]) for us since yesterday: ``` [...] drivers/char/hpet.c: In function 'hpet_read': drivers/char/hpet.c:311:36: error: 'compat_ulong_t' undeclared (first use in this function) 311 | if (count < sizeof(compat_ulong_t)) | ^~~~~~~~~~~~~~ drivers/char/hpet.c:311:36: note: each undeclared identifier is reported only once for each function it appears in [...] ``` ...as it uses a type not known to ia64 (and possibly other architectures) w/o also including: ``` asm-generic: Move common compat types to asm-generic/compat.h https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fb3739759474d150a9927b920a80ea2afb4c2a51 ``` The latter seems to be in mainline only since v4.20-rc1 and fixes the non-HP-Sim ia64 build ([2]) for me. So fb3739759474d150a9927b920a80ea2afb4c2a51 should be included in linux-4.19.y, too, if a589979f345720aca32ff43a2ccaa16a70871b9e stays in.
