patch "xhci: Fix perceived dead host due to runtime suspend race with event" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled xhci: Fix perceived dead host due to runtime suspend race with event to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 229bc19fd7aca4f37964af06e3583c1c8f36b5d6 Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Thu, 21 Jun 2018 16:19:41 +0300 Subject: xhci: Fix perceived dead host due to runtime suspend race with event handler Don't rely on event interrupt (EINT) bit alone to detect pending port change in resume. If no change event is detected the host may be suspended again, oterwise roothubs are resumed. There is a lag in xHC setting EINT. If we don't notice the pending change in resume, and the controller is runtime suspeded again, it causes the event handler to assume host is dead as it will fail to read xHC registers once PCI puts the controller to D3 state.

[PATCH] x86/efi: Fix efi_call_phys_epilog() with CONFIG_X86_5LEVEL=y

by Kirill A. Shutemov

Open-coded page table entry checks don't work correctly when we fold the page table level at runtime. pgd_present() on 4-level paging machine always returns true, but open-coded version of the check may return false-negative result and we silently skip the rest of the loop body in efi_call_phys_epilog().

[PATCH] ALSA: hda/realtek - Fix the problem of two front mics on more machines

by Hui Wang

We have 3 more Lenovo machines, they all have 2 front mics on them, so they need the fixup to change the location for one of two mics. Among these 3 Lenovo machines, one of them has the same pin cfg as the machine with subid 0x17aa3138, so use the pin cfg table to apply fixup for them. The rest machines don't share the same pin cfg, so far use the subid to apply fixup for them.
