Subject: [patch V181 12/54] x86/uv: Use the right tlbflush API
Date: Wed, 20 Dec 2017 22:35:15 +0100	[thread overview]
Message-ID: <20171220215441.592561621@linutronix.de> (raw)
In-Reply-To: <20171220213503.672610178@linutronix.de>

[-- Attachment #1: 0065-x86-uv-Use-the-right-tlbflush-API.patch --]
[-- Type: text/plain, Size: 1782 bytes --]

From: Peter Zijlstra <peterz@infradead.org>

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.
