[PATCH] pinctrl: baytrail: Really serialize all register accesses

by Hans de Goede

Commit 39ce8150a079 ("pinctrl: baytrail: Serialize all register access") added a spinlock around all register accesses because: "There is a hardware issue in Intel Baytrail where concurrent GPIO register access might result reads of 0xffffffff and writes might get dropped completely." Testing has shown that this does not catch all cases, there are still 2 problems remaining 1) The original fix uses a spinlock per byt_gpio device / struct, additional testing has shown that this is not sufficient concurent accesses to 2 different GPIO banks also suffer from the same problem. This commit fixes this by moving to a single global lock. 2) The original fix did not add a lock around the register accesses in the suspend/resume handling. Since pinctrl-baytrail.c is using normal suspend/resume handlers, interrupts are still enabled during suspend/resume handling. Nothing should be using the GPIOs when they are being taken down, _but_ the GPIOs themselves may still cause interrupts, which are likely to use (read) the triggering GPIO. So we need to protect against concurrent GPIO register accesses in the suspend/resume handlers too. This commit fixes this by adding the missing spin_lock / unlock calls. The 2 fixes together fix the Acer Switch 10 SW5-012 getting completely confused after a suspend resume. The DSDT for this device has a bug in its _LID method which reprograms the home and power button trigger- flags requesting both high and low _level_ interrupts so the IRQs for these 2 GPIOs continuously fire. This combined with the saving of registers during suspend, triggers concurrent GPIO register accesses resulting in saving 0xffffffff as pconf0 value during suspend and then when restoring this on resume the pinmux settings get all messed up, resulting in various I2C busses being stuck, the wifi no longer working and often the tablet simply not coming out of suspend at all.

[PATCH AUTOSEL 4.20 001/117] netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets

by Sasha Levin

From: Stefano Brivio <sbrivio(a)redhat.com> [ Upstream commit 8cc4ccf58379935f3ad456cc34e61c4e4c921d0e ] There doesn't seem to be any reason to restrict MAC address matching to source MAC addresses in set types bitmap:ipmac, hash:ipmac and hash:mac.

Fix bad backport to stable v3.16+

by Song Liu

Hi, As reported by Thorsten Knabe <linux(a)thorsten-knabe.de>. commit 4f4fd7c5798b ("Don't jump to compute_result state from check_result state") was back ported to v3.16+. However, this fix was wrong. Please back port the following two commits to fix this issue. commit a25d8c327bb4 ("Revert "Don't jump to compute_result state from check_result state"") commit b2176a1dfb51 ("md/raid: raid5 preserve the writeback action after the parity check") Thanks, Song

stable request: PCI: tegra: Enable Relaxed Ordering only for Tegra20 & Tegra30

by Vidya Sagar

Hi Greg, We noticed that the Tegra PCIe host controller driver enabled "Relaxed Ordering" bit in the PCIe configuration space for "all" devices erroneously. We pushed a fix for this through the commit: 7be142caabc4780b13a522c485abc806de5c4114 and it has been soaking in main line for the last four months. Based on the discussion we had @ http://patchwork.ozlabs.org/patch/1127604/ we would now like to push it to the following stable kernels 4.19 : Applies cleanly 3.16, 4.4, 4.9 & 4.14 : Following equivalent patch needs to be used as the file was at drivers/pci/host/pci-tegra.c earlier (and moved to drivers/pci/controller/pci-tegra.c starting 4.19) --- drivers/pci/host/pci-tegra.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/pci/host/pci-tegra.c b/drivers/pci/host/pci-tegra.c index 083cf37ca047..56daa83b041c 100644 --- a/drivers/pci/host/pci-tegra.c +++ b/drivers/pci/host/pci-tegra.c @@ -615,12 +615,15 @@ DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_NVIDIA, 0x0bf1, tegra_pcie_fixup_class); DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_NVIDIA, 0x0e1c, tegra_pcie_fixup_class); DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_NVIDIA, 0x0e1d, tegra_pcie_fixup_class); -/* Tegra PCIE requires relaxed ordering */ +/* Tegra20 and Tegra30 PCIE requires relaxed ordering */ static void tegra_pcie_relax_enable(struct pci_dev *dev) { pcie_capability_set_word(dev, PCI_EXP_DEVCTL, PCI_EXP_DEVCTL_RELAX_EN); } -DECLARE_PCI_FIXUP_FINAL(PCI_ANY_ID, PCI_ANY_ID, tegra_pcie_relax_enable); +DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_NVIDIA, 0x0bf0, tegra_pcie_relax_enable); +DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_NVIDIA, 0x0bf1, tegra_pcie_relax_enable); +DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_NVIDIA, 0x0e1c, tegra_pcie_relax_enable); +DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_NVIDIA, 0x0e1d, tegra_pcie_relax_enable); static int tegra_pcie_setup(int nr, struct pci_sys_data *sys) { -- 2.17.1

[PATCH v3.16] alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP

by Petr Vorel

From: Thadeu Lima de Souza Cascardo <cascardo(a)canonical.com> ENOTSUPP is not supposed to be returned to userspace. This was found on an OpenPower machine, where the RTC does not support set_alarm. On that system, a clock_nanosleep(CLOCK_REALTIME_ALARM, ...) results in "524 Unknown error 524" Replace it with EOPNOTSUPP which results in the expected "95 Operation not supported" error.

[PATCH for 4.19-stable 2/2] mm/memory_hotplug: fix updating the node span

by David Hildenbrand

commit 656d571193262a11c2daa4012e53e4d645bbce56 upstream. We recently started updating the node span based on the zone span to avoid touching uninitialized memmaps. Currently, we will always detect the node span to start at 0, meaning a node can easily span too many pages. pgdat_is_empty() will still work correctly if all zones span no pages. We should skip over all zones without spanned pages and properly handle the first detected zone that spans pages. Unfortunately, in contrast to the zone span (/proc/zoneinfo), the node span cannot easily be inspected and tested. The node span gives no real guarantees when an architecture supports memory hotplug, meaning it can easily contain holes or span pages of different nodes. The node span is not really used after init on architectures that support memory hotplug. E.g., we use it in mm/memory_hotplug.c:try_offline_node() and in mm/kmemleak.c:kmemleak_scan(). These users seem to be fine.
