[PATCH v2 0/7] set clang minimum version to 10.0.1

From: Nick Desaulniers
Date: Mon Aug 31 2020 - 20:23:45 EST


Adds a compile time #error to compiler-clang.h setting the effective
minimum supported version to clang 10.0.1. A separate patch has already
been picked up into the Documentation/ tree also confirming the version.

Next are a series of reverts. One for 32b arm is a partial revert.

Then Marco suggested fixes to KASAN docs.

Finally, improve the warning for GCC too as per Kees.

Patches after 001 are new for v2.

kasan: Remove mentions of unsupported Clang versions
