At the very end of the MACsec block initialization in the MSCC PHY driver, the MACsec "protocol mode" is set. This setting should be set based on the PHY id within the package, as the bank used to access the register used depends on this. This was not done correctly, and only the first bank was used leading to the two upper PHYs being unstable when using the VSC8584. This patch fixes it.

Commit 14b41a29 ("net: stmmac: Delete txtimer in suspend") was the first attempt to fix a race between mod_timer() and setup_timer() during stmmac_resume(). However the issue still exists as the commit only addressed half of the issue. Same race can still happen as stmmac_resume() re-attaches interface way too early - even before hardware is fully initialized. Worse, doing so allows network traffic to restart and stmmac_tx_timer_arm() being called in the middle of stmmac_resume(), which re-init tx timers in stmmac_init_coalesce(). timer_list will be corrupted and system crashes as a result of race between mod_timer() and setup_timer(). systemd--1995 2.... 552950018us : stmmac_suspend: 4994 ksoftirq-9 0..s2 553123133us : stmmac_tx_timer_arm: 2276 systemd--1995 0.... 553127896us : stmmac_resume: 5101 systemd--320 7...2 553132752us : stmmac_tx_timer_arm: 2276 (sd-exec-1999 5...2 553135204us : stmmac_tx_timer_arm: 2276 --------------------------------- pc : run_timer_softirq+0x468/0x5e0 lr : run_timer_softirq+0x570/0x5e0 Call trace: run_timer_softirq+0x468/0x5e0 __do_softirq+0x124/0x398 irq_exit+0xd8/0xe0 __handle_domain_irq+0x6c/0xc0 gic_handle_irq+0x60/0xb0 el1_irq+0xb8/0x180 arch_cpu_idle+0x38/0x230 default_idle_call+0x24/0x3c do_idle+0x1e0/0x2b8 cpu_startup_entry+0x28/0x48 secondary_start_kernel+0x1b4/0x208 Fix this by deferring netif_device_attach() to the end of stmmac_resume().

The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to page table entry to access srmmu_nocache_pool. But since sparc32 has only three actual page table levels, pgd, p4d and pud are essentially the same thing and pgd_offset() and p4d_offset() are no-ops, the __nocache_fix() should be done only at PUD level. Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it only for PUD and lower levels.

During early boot, while KASAN is not yet initialized, it is possible to enter reporting code-path and end up in kasan_report(). While uninitialized, the branch there prevents generating any reports, however, under certain circumstances when branches are being traced (TRACE_BRANCH_PROFILING), we may recurse deep enough to cause kernel reboots without warning. To prevent similar issues in future, we should disable branch tracing for the core runtime.

Assume we have kmem configured and loaded: [root@localhost ~]# cat /proc/iomem ... 140000000-33fffffff : Persistent Memory$ 140000000-1481fffff : namespace0.0 150000000-33fffffff : dax0.0 150000000-33fffffff : System RAM Assume we try to unload kmem. This force-unloading will work, even if memory cannot get removed from the system. [root@localhost ~]# rmmod kmem [ 86.380228] removing memory fails, because memory [0x0000000150000000-0x0000000157ffffff] is onlined ... [ 86.431225] kmem dax0.0: DAX region [mem 0x150000000-0x33fffffff] cannot be hotremoved until the next reboot Now, we can reconfigure the namespace: [root@localhost ~]# ndctl create-namespace --force --reconfig=namespace0.0 --mode=devdax [ 131.409351] nd_pmem namespace0.0: could not reserve region [mem 0x140000000-0x33fffffff]dax [ 131.410147] nd_pmem: probe of namespace0.0 failed with error -16namespace0.0 --mode=devdax ... This fails as expected due to the busy memory resource, and the memory cannot be used. However, the dax0.0 device is removed, and along its name. The name of the memory resource now points at freed memory (name of the device): [root@localhost ~]# cat /proc/iomem ... 140000000-33fffffff : Persistent Memory 140000000-1481fffff : namespace0.0 150000000-33fffffff : �_�^7_��/_��wR��WQ���^��� ... 150000000-33fffffff : System RAM We have to make sure to duplicate the string.

This reverts commit 4ef12f71. Guenter reports: All my arm64be (arm64 big endian) boot tests crash with this patch applied. Reverting it fixes the problem. Crash log and bisect results (from pending-fixes branch) below. And also: arm64 images don't crash but report lots of "poison overwritten" backtraces like the one below. On arm, I see "refcount_t: underflow", also attached. I didn't bisect those, but given the context I would suspect the same culprit.

Pull drm fixes from Dave Airlie: "Things seemed to have quieten down, though no i915 pull (I even gave them an extra 12 hours in case they were late). The amdgpu floating point fix is probably the largest, but it just moves some code around to it doesn't do fpu stuff outside the fpu boundaries.
