Kees Cook	918327e9b7	ubsan: Remove CONFIG_UBSAN_SANITIZE_ALL ... For simplicity in splitting out UBSan options into separate rules, remove CONFIG_UBSAN_SANITIZE_ALL, effectively defaulting to "y", which is how it is generally used anyway. (There are no ":= y" cases beyond where a specific file is enabled when a top-level ":= n" is in effect.)

Andrey Konovalov	9fb2047d23	Documentation: ubsan: drop "the" from article title ... Drop "the" from the title of the documentation article for UBSAN, as it is redundant. Also add SPDX-License-Identifier for ubsan.rst.

Kees Cook	c637693b20	ubsan: remove UBSAN_MISC in favor of individual options ... Make each UBSAN option individually selectable and remove UBSAN_MISC which no longer has any purpose. Add help text for each Kconfig, and include a reference to the Clang sanitizer documentation. Disable unsigned overflow by default (not available with GCC and makes x86 unbootable with Clang). Disable unreachable when objtool is in use (redundant and confuses things: instrumentation appears at unreachable locations).
