To ensure the safety of this mitigation, the kernel must ensure that the
safe return sequence is itself free from attacker interference. In Zen3
and Zen4, this is accomplished by creating a BTB alias between the
untraining function srso_untrain_ret_alias() and the safe return
function srso_safe_ret_alias() which results in evicting a potentially
untraining function srso_alias_untrain_ret() and the safe return
function srso_alias_safe_ret() which results in evicting a potentially
poisoned BTB entry and using that safe one for all function returns.
In older Zen1 and Zen2, this is accomplished using a reinterpretation

Newer binutils versions default to ISA spec version 20191213 which
moves some instructions from the I extension to the Zicsr and Zifencei
extensions.
Binutils-2.38 and GCC-12.1.0 bumped the default ISA spec to the newer
20191213 version, which moves some instructions from the I extension to
the Zicsr and Zifencei extensions. This requires explicitly specifying
Zicsr and Zifencei when binutils >= 2.38 or GCC >= 12.1.0. Zicsr
and Zifencei are supported in binutils from version 2.36 onwards.
To make life easier, and avoid forcing toolchains that default to a
newer ISA spec to version 2.2, relax the check to binutils >= 2.36.
For clang < 17 or GCC < 11.1.0, for which this is not possible, this is
dealt with in CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC.

Certain versions of clang do not support zicsr and zifencei via -march
but newer versions of binutils require it for the reasons noted in the
help text of CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI. This
option causes an older ISA spec compatible with these older versions
of clang to be passed to GAS, which has the same result as passing zicsr
and zifencei to -march.
