2020-01-30compat: support building for RHEL-8.2Ilie Halip
RedHat backported some more changes, now released as kernel 4.18.0-168.el8. To maintain compatibility with kernel -147, a new macro is introduced: ISRHEL82. Compile-tested with the -168 and -147 kernels. Signed-off-by: Ilie Halip <ilie.halip@gmail.com> [zx2c4: we normally only support the latest RHEL, but having some beta support for the time being sounds like a good plan, given that there may be interest from RedHat in actually merging this into their kernels.] Signed-off-by: Jason A.

2019-06-25global: switch to coarse ktimeJason A. Donenfeld
Coarse ktime is broken until [1] in 5.2 and kernels without the backport, so we use fallback code there. The fallback code has also been improved significantly. It now only uses slower clocks on kernels < 3.17, at the expense of some accuracy we're not overly concerned about.

2018-12-07compat: don't undef BUILD_BUG_ON for Clang >=8Nathan Chancellor
This has been fixed upstream. To keep this hack working for toolchains that don't have it, use CONFIG_CLANG_VERSION, which was added in commit 469cb7376c06 ("kconfig: add CC_IS_CLANG and CLANG_VERSION"), introduced in 4.18. I have added the '!defined(CONFIG_CLANG_VERSION)' to keep the hack around for Android. Most custom kernel developers are using AOSP's Clang, which currently does not have the fix and might not for a while (although it is probably on Google's mind given that it has been an issue for ChromeOS on 4.19: https://crbug.com/897215). I have verified this change against my Pixel 2 kernel and 4.20-rc3 with the latest ToT Clang.
