Revert "x86/bugs: Make spectre user default depend on MITIGATION_SPECTRE_V2" on v6.6 and older
This reverts commit 7adb96687ce8819de5c7bb172c4eeb6e45736e06 which is
commit 98fdaeb296f51ef08e727a7cc72e5b5c864c4f4d upstream.
commit 7adb96687ce8 ("x86/bugs: Make spectre user default depend on
MITIGATION_SPECTRE_V2") depends on commit 72c70f480a70 ("x86/bugs: Add
a separate config for Spectre V2"), which introduced
MITIGATION_SPECTRE_V2.
commit 72c70f480a70 ("x86/bugs: Add a separate config for Spectre V2")
never landed in stable tree, thus, stable tree doesn't have
MITIGATION_SPECTRE_V2, that said, commit 7adb96687ce8 ("x86/bugs: Make
spectre user default depend on MITIGATION_SPECTRE_V2") has no value if
the dependecy was not applied.
Revert commit 7adb96687ce8 ("x86/bugs: Make spectre user default
depend on MITIGATION_SPECTRE_V2") in stable kernel which landed in in
5.4.294, 5.10.238, 5.15.185, 6.1.141 and 6.6.93 stable versions.
