From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/drivers/misc/mei/hw-txe.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'kernel/drivers/misc/mei/hw-txe.c') diff --git a/kernel/drivers/misc/mei/hw-txe.c b/kernel/drivers/misc/mei/hw-txe.c index bae680c64..396d75d9f 100644 --- a/kernel/drivers/misc/mei/hw-txe.c +++ b/kernel/drivers/misc/mei/hw-txe.c @@ -972,11 +972,13 @@ static bool mei_txe_check_and_ack_intrs(struct mei_device *dev, bool do_ack) hisr = mei_txe_br_reg_read(hw, HISR_REG); aliveness = mei_txe_aliveness_get(dev); - if (hhisr & IPC_HHIER_SEC && aliveness) + if (hhisr & IPC_HHIER_SEC && aliveness) { ipc_isr = mei_txe_sec_reg_read_silent(hw, SEC_IPC_HOST_INT_STATUS_REG); - else + } else { ipc_isr = 0; + hhisr &= ~IPC_HHIER_SEC; + } generated = generated || (hisr & HISR_INT_STS_MSK) || -- cgit 1.2.3-korg
