[Linux-stable-mirror] Patch "x86/smpboot: Remove stale TLB flush invocations" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled x86/smpboot: Remove stale TLB flush invocations to the 4.9-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: x86-smpboot-remove-stale-tlb-flush-invocations.patch and it can be found in the queue-4.9 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 322f8b8b340c824aef891342b0f5795d15e11562 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner <tglx(a)linutronix.de> Date: Sat, 30 Dec 2017 22:13:53 +0100 Subject: x86/smpboot: Remove stale TLB flush invocations From: Thomas Gleixner <tglx(a)linutronix.de> commit 322f8b8b340c824aef891342b0f5795d15e11562 upstream. smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector() invoke local_flush_tlb() for no obvious reason. Digging in history revealed that the original code in the 2.1 era added those because the code manipulated a swapper_pg_dir pagetable entry. The pagetable manipulation was removed long ago in the 2.3 timeframe, but the TLB flush invocations stayed around forever. Remove them along with the pointless pr_debug()s which come from the same 2.1 change.

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking advantage of the fact that existing devices work with sendsetup = true too. Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID 0x9090.

USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a off by one in commit 81cf4a45360f ("USB: core: Add type-specific length check of BOS descriptors") It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes the zero based SSAC as argument, not the actual count of sublink speed attributes. USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."

[Linux-stable-mirror] Patch "timers: Use deferrable base independent of base::nohz_active" has been added to the 4.9-stable tree

This is a note to let you know that I've just added the patch titled timers: Use deferrable base independent of base::nohz_active to the 4.9-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: timers-use-deferrable-base-independent-of-base-nohz_active.patch and it can be found in the queue-4.9 subdirectory.

During boot and before base::nohz_active is set in the timer bases, deferrable timers are enqueued into the standard timer base. This works correctly as long as base::nohz_active is false. Once it base::nohz_active is set and a timer which was enqueued before that is accessed the lock selector code choses the lock of the deferred base. This causes unlocked access to the standard base and in case the timer is removed it does not clear the pending flag in the standard base bitmap which causes get_next_timer_interrupt() to return bogus values. To prevent that, the deferrable timers must be enqueued in the deferrable base, even when base::nohz_active is not set. Those deferrable timers also need to be expired unconditional.
