From 538f127cd3bcf76071139f4bfe9cc3b2a46f3b3d Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Sun, 22 Dec 2019 23:34:04 +0000 Subject: [PATCH] x86/hyper-v: Add "polling" bit to hv_synic_sint That bit is documented in TLFS 5.0c as follows: Setting the polling bit will have the effect of unmasking an interrupt source, except that an actual interrupt is not generated.
