Commit 2a9127fc ("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.

On A20R machines the interrupt pending bits in cause register need to be updated by requesting the chipset to do it. This needs to be done to find the interrupt cause and after interrupt service. In commit 0b888c7f ("MIPS: SNI: Convert to new irq_chip functions") the function to do after service update got lost, which caused spurious interrupts.

'perf stat' displays miss ratio of L1-dcache, L1-icache, dTLB cache, iTLB cache and LL-cache. Take L1-dcache for example, miss ratio is caculated as "L1-dcache-load-misses/L1-dcache-loads". So "of all L1-dcache hits" is unsuitable to describe it, and "of all L1-dcache accesses" seems better. The comments of L1-icache, dTLB cache, iTLB cache and LL-cache are fixed in the same way.

It's dangerous to free the original metric when it's called from resolve_metric() as it's already in the metric_list and might have other resources too. Instead, it'd better let them bail out and be released properly at the later stage. So add a check when it's called from metricgroup__add_metric() and release it. Also make sure that mp is set properly.

The metricgroup__add_metric() can find multiple match for a metric group and it's possible to fail. Also it can fail in the middle like in resolve_metric() even for single metric.

If events in a group explicitly set a frequency or period with leader sampling, don't disable the samples on those events. Prior to 5.8: perf record -e '{cycles/period=12345000/,instructions/period=6789000/}:S' would clear the attributes then apply the config terms. In commit 5f342788 leader sampling configuration was moved to after applying the config terms, in the example, making the instructions' event have its period cleared. This change makes it so that sampling is only disabled if configuration terms aren't present.

Yunhai Zhang recently fixed a VGA software scrollback bug in commit ebfdfeea ("vgacon: Fix for missing check in scrollback handling"), but that then made people look more closely at some of this code, and there were more problems on the vgacon side, but also the fbcon software scrollback. We don't really have anybody who maintains this code - probably because nobody actually _uses_ it any more. Sure, people still use both VGA and the framebuffer consoles, but they are no longer the main user interfaces to the kernel, and haven't been for decades, so these kinds of extra features end up bitrotting and not really being used. So rather than try to maintain a likely unused set of code, I'll just aggressively remove it, and see if anybody even notices. Maybe there are people who haven't jumped on the whole GUI badnwagon yet, and think it's just a fad. And maybe those people use the scrollback code. If that turns out to be the case, we can resurrect this again, once we've found the sucker^Wmaintainer for it who actually uses it.

This (and the VGA soft scrollback) turns out to have various nasty small special cases that nobody really is willing to fight. The soft scrollback code was really useful a few decades ago when you typically used the console interactively as the main way to interact with the machine, but that just isn't the case any more. So it's not worth dragging along.

When faulting in the pages for the user supplied buffer for the search ioctl, we are passing only the base address of the buffer to the function fault_in_pages_writeable(). This means that after the first iteration of the while loop that searches for leaves, when we have a non-zero offset, stored in 'sk_offset', we try to fault in a wrong page range. So fix this by adding the offset in 'sk_offset' to the base address of the user supplied buffer when calling fault_in_pages_writeable(). Several users have reported that the applications compsize and bees have started to operate incorrectly since commit a48b73ec ("btrfs: fix potential deadlock in the search ioctl") was added to stable trees, and these applications make heavy use of the search ioctls. This fixes their issues.
