[PATCH] clk: sunxi-ng: a31: Fix CLK_OUT_* clock ops

by Chen-Yu Tsai

When support for the A31/A31s CCU was first added, the clock ops for the CLK_OUT_* clocks was set to the wrong type. The clocks are MP-type, but the ops was set for div (M) clocks. This went unnoticed until now. This was because while they are different clocks, their data structures aligned in a way that ccu_div_ops would access the second ccu_div_internal and ccu_mux_internal structures, which were valid, if not incorrect. Furthermore, the use of these CLK_OUT_* was for feeding a precise 32.768 kHz clock signal to the WiFi chip. This was achievable by using the parent with the same clock rate and no divider. So the incorrect divider setting did not affect this usage. Commit 946797aa3f08 ("clk: sunxi-ng: Support fixed post-dividers on MP style clocks") added a new field to the ccu_mp structure, which broke the aforementioned alignment. Now the system crashes as div_ops tries to look up a nonexistent table.

[PATCH v2] extcon: intel-cht-wc: Also set direction and drv flags for V5 boost GPIO

by Hans de Goede

Sometimes (firmware bug?) the V5 boost GPIO is not configured as output by the BIOS, leading to the 5V boost convertor being permanently on, Explicitly set the direction and drv flags rather then inheriting them from the firmware to fix this.

[RFC] Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking

by Hans de Goede

Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA btusb devices. But it turns out that the resume problems are not caused by the QCA Rome chipset, on most platforms it resumes fine. The resume problems are actually a platform problem (likely the platform cutting all power when suspended). The USB_QUIRK_RESET_RESUME quirk also disable runtime suspend, so by matching on usb-ids, we're causing all boards with these chips to use extra power, to fix resume problems which only happen on some boards. This commit fixes this by applying the quirk based on DMI matching instead of on usb-ids, so that we match the platform and not the chipset.

Up to Coffeelake we could deduce this GT number from the device ID. This doesn't seem to be the case anymore. This change reorders pciids per GT and adds a gt field to intel_device_info. We set this field on the following platforms : - SNB/IVB/HSW/BDW/SKL/KBL/CFL/CNL Before & After : $ modinfo drivers/gpu/drm/i915/i915.ko | grep ^alias | wc -l 209 v2: Add SNB & IVB (Chris) v3: Fix compilation error in early-quirks (Lionel) v4: Fix inconsistency between FEATURE/PLATFORM macros (Ville) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin(a)intel.com> Reviewed-by: Chris Wilson <chris(a)chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20170830161208.29221-2-lionel… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/gpu/drm/i915/i915_drv.h | 1 drivers/gpu/drm/i915/i915_pci.c | 193 +++++++++++++++++++++++++++++++--------- include/drm/i915_pciids.h | 152 +++++++++++++++++++------------ 3 files changed, 246 insertions(+), 100 deletions(-) --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -842,6 +842,7 @@ struct intel_device_info { u8 gen; u16 gen_mask; enum intel_platform platform; + u8 gt; /* GT number, 0 if undefined */ u8 ring_mask; /* Rings supported by the HW */ u8 num_rings; #define DEFINE_FLAG(name) u8 name:1 --- a/drivers/gpu/drm/i915/i915_pci.c +++ b/drivers/gpu/drm/i915/i915_pci.c @@ -224,15 +224,34 @@ static const struct intel_device_info in GEN_DEFAULT_PIPEOFFSETS, \ CURSOR_OFFSETS -static const struct intel_device_info intel_sandybridge_d_info = { -

Patch "mm, memory_hotplug: fix memmap initialization" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled mm, memory_hotplug: fix memmap initialization to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: mm-memory_hotplug-fix-memmap-initialization.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 9bb5a391f9a5707e04763cf14298fc4cc29bfecd Mon Sep 17 00:00:00 2001 From: Michal Hocko <mhocko(a)suse.com> Date: Wed, 31 Jan 2018 16:21:14 -0800 Subject: mm, memory_hotplug: fix memmap initialization From: Michal Hocko <mhocko(a)suse.com> commit 9bb5a391f9a5707e04763cf14298fc4cc29bfecd upstream. Bharata has noticed that onlining a newly added memory doesn't increase the total memory, pointing to commit f7f99100d8d9 ("mm: stop zeroing memory during allocation in vmemmap") as a culprit. This commit has changed the way how the memory for memmaps is initialized and moves it from the allocation time to the initialization time. This works properly for the early memmap init path. It doesn't work for the memory hotplug though because we need to mark page as reserved when the sparsemem section is created and later initialize it completely during onlining. memmap_init_zone is called in the early stage of onlining. With the current code it calls __init_single_page and as such it clears up the whole stage and therefore online_pages_range skips those pages. Fix this by skipping mm_zero_struct_page in __init_single_page for memory hotplug path. This is quite uggly but unifying both early init and memory hotplug init paths is a large project. Make sure we plug the regression at least.

[PATCH] arm64: cpufeature: Fix CTR_EL0 field definitions

by Will Deacon

Our field definitions for CTR_EL0 suffer from a number of problems: - The IDC and DIC fields are missing, which causes us to enable CTR trapping on CPUs with either of these returning non-zero values. - The ERG is FTR_LOWER_SAFE, whereas it should be treated like CWG as FTR_HIGHER_SAFE so that applications can use it to avoid false sharing. - [nit] A RES1 field is described as "RAO" This patch updates the CTR_EL0 field definitions to fix these issues.
