Subject: [PATCH 5/9] x86/uv: Use the right tlbflush API
Date: Tue, 05 Dec 2017 13:34:50 +0100 [thread overview]
Message-ID: <20171205123820.134563117@infradead.org> (raw)
In-Reply-To: <20171205123444.990868007@infradead.org>
[-- Attachment #1: peterz-tlb-uv.patch --]
[-- Type: text/plain, Size: 938 bytes --]
Since uv_flush_tlb_others() implements flush_tlb_others() which is
about flushing user mappings, we should use __flush_tlb_single(),
which too is about flushing user mappings.
