Subject: [PATCH v2 11/11] x86/paravirt: remove unneeded mmu related paravirt ops bits
Date: Mon, 13 Aug 2018 09:37:39 +0200	[thread overview]
Message-ID: <20180813073739.26108-12-jgross@suse.com> (raw)
In-Reply-To: <20180813073739.26108-1-jgross@suse.com>

There is no need to have 32-bit code for CONFIG_PGTABLE_LEVELS >= 4.
Remove it.
