Remove the following warnings seen when building with W=1. Warning (unique_unit_address): /soc/timer@40000c00: duplicate unit-address (also used in node /soc/timers@40000c00) This approach is based on some discussions[1], to restructure the dtsi and dts files. Timer5 is enabled by default on stm32f4 series, to act as clockevent. In order to get rid of the W=1 warning, and be compliant with dt-schemas (e.g. dtbs_check): - In stm32f429.dtsi: . Keep the more complete timers5 description . Remove the most simple timer5 node that is duplicate - In each board: . adopt "st,stm32-timer" compatible for timers5, also add the interrupt . use /delete-property/ and /delete-node/ so the it matches the clockevent bindings Note: all this is done in one shot (e.g. not split) to keep clockevent functionality.

By default, timer5 is left enabled to be used as clockevent. Remove all other timer clockevent nodes that are currently unused and duplicated.

Patch series "ocfs2: fix a deadlock case". This fixes a deadlock case in ocfs2. We firstly export jbd2 symbols jbd2_journal_[grab|put]_journal_head as preparation and later use them in ocfs2 insread of jbd_[lock|unlock]_bh_journal_head to fix the deadlock. This patch (of 2): This exports symbols jbd2_journal_[grab|put]_journal_head, which will be used outside modules, e.g. ocfs2.

With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform dynamic checks using __builtin_object_size(ptr), which when failed will panic the kernel. Because the KASAN test deliberately performs out-of-bounds operations, the kernel panics with FORTIFY_SOURCE, for example: | kernel BUG at lib/string_helpers.c:910! | invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI | CPU: 1 PID: 137 Comm: kunit_try_catch Tainted: G B 5.16.0-rc3+ #3 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 | RIP: 0010:fortify_panic+0x19/0x1b | ... | Call Trace: | kmalloc_oob_in_memset.cold+0x16/0x16 | ... Fix it by also hiding `ptr` from the optimizer, which will ensure that __builtin_object_size() does not return a valid size, preventing fortified string functions from panicking.

memory_failure_dev_pagemap() at the moment assumes base pages (e.g. dax_lock_page()). For devmap with compound pages fetch the compound_head in case a tail page memory failure is being handled. Currently this is a nop, but in the advent of compound pages in dev_pagemap it allows memory_failure_dev_pagemap() to keep working. Without this fix memory-failure handling (i.e. MCEs on pmem) with device-dax configured namespaces will regress (and crash).
