Subject: [RFC PATCH] time.h: drop non-standard and out-of-date CLOCK_SGI_CYCLE
This definition was introduced in commit d74e462a ("add CLOCK_TAI (and
CLOCK_SGI_CYCLE) clock ids to time.h added in linux-v3.10 commit
1ff3c9677bff7e468e0c487d0ffefe4e901d33f4"). However, it's actually a
platform specific feature, available only on SGI SN2 IA64 systems. Its
Linux support has been removed later in commit 07903ada9613
("mmtimer: Remove the SGI SN2 mmtimer driver").
Having this definition is known to cause applications misdetect the
environment. There's no reason to keep a non-standard, seldom-available
and removed-since-4.13-kernel macro in a standard header.
