But jiffies is only updated in the timer interrupt, so when kgdb_cpu_enter() begins to run there may already be nearly one rcu check period after jiffies. Since all interrupts are disabled during kgdb_cpu_enter(), jiffies will not be updated. When kgdb_cpu_enter() returns, rcu_state.jiffies_stall maybe already gets timeout. We can set rcu_state.jiffies_stall to two rcu check periods later, e.g. jiffies + (rcu_jiffies_till_stall_check() * 2) in rcu_cpu_stall_reset() to avoid this problem. But this isn't a complete solution because kgdb may take a very long time in irq disabled context. Instead, update jiffies at the beginning of rcu_cpu_stall_reset() can solve all kinds of problems.

[PATCH] mm: allow a controlled amount of unfairness in the page lock

by Maximilian Heyne

From: Linus Torvalds <torvalds(a)linux-foundation.org> [ upstream commit 5ef64cc8987a9211d3f3667331ba3411a94ddc79 ] Commit 2a9127fcf229 ("mm: rewrite wait_on_page_bit_common() logic") made the page locking entirely fair, in that if a waiter came in while the lock was held, the lock would be transferred to the lockers strictly in order. That was intended to finally get rid of the long-reported watchdog failures that involved the page lock under extreme load, where a process could end up waiting essentially forever, as other page lockers stole the lock from under it. It also improved some benchmarks, but it ended up causing huge performance regressions on others, simply because fair lock behavior doesn't end up giving out the lock as aggressively, causing better worst-case latency, but potentially much worse average latencies and throughput. Instead of reverting that change entirely, this introduces a controlled amount of unfairness, with a sysctl knob to tune it if somebody needs to. But the default value should hopefully be good for any normal load, allowing a few rounds of lock stealing, but enforcing the strict ordering before the lock has been stolen too many times. There is also a hint from Matthieu Baerts that the fair page coloring may end up exposing an ABBA deadlock that is hidden by the usual optimistic lock stealing, and while the unfairness doesn't fix the fundamental issue (and I'm still looking at that), it avoids it in practice. The amount of unfairness can be modified by writing a new value to the 'sysctl_page_lock_unfairness' variable (default value of 5, exposed through /proc/sys/vm/page_lock_unfairness), but that is hopefully something we'd use mainly for debugging rather than being necessary for any deep system tuning. This whole issue has exposed just how critical the page lock can be, and how contended it gets under certain locks. And the main contention doesn't really seem to be anything related to IO (which was the origin of this lock), but for things like just verifying that the page file mapping is stable while faulting in the page into a page table.

[PATCH v2 2/2] riscv: correct pt_level name via pgtable_l5/4_enabled

by Palmer Dabbelt

From: Song Shuai <suagrfillet(a)gmail.com> The pt_level uses CONFIG_PGTABLE_LEVELS to display page table names. But if page mode is downgraded from kernel cmdline or restricted by the hardware in 64BIT, it will give a wrong name. Like, using no4lvl for sv39, ptdump named the 1G-mapping as "PUD" that should be "PGD": 0xffffffd840000000-0xffffffd900000000 0x00000000c0000000 3G PUD D A G . . W R V So select "P4D/PUD" or "PGD" via pgtable_l5/4_enabled to correct it.

[PATCH] rcu/tree: Defer setting of jiffies during stall reset

by Joel Fernandes (Google)

There are instances where rcu_cpu_stall_reset() is called when jiffies did not get a chance to update for a long time. Before jiffies is updated, the CPU stall detector can go off triggering false-positives where a just-started grace period appears to be ages old. In the past, we disabled stall detection in rcu_cpu_stall_reset() however this got changed [1]. This is resulting in false-positives in KGDB usecase [2]. Fix this by deferring the update of jiffies to the third run of the FQS loop. This is more robust, as, even if rcu_cpu_stall_reset() is called just before jiffies is read, we would end up pushing out the jiffies read by 3 more FQS loops. Meanwhile the CPU stall detection will be delayed and we will not get any false positives.

[PATCH] ssb-main: Fix division by zero in ssb_calc_clock_rate()

by Rand Deeb

In the line 910, the value of m1 may be zero, so there is a possibility of dividing by zero, we fixed it by checking the values before dividing (found with SVACE). In the same way, after checking and reading the function, we found that lines 906, 908, 912 have the same situation, so we fixed them as well.
