Sebastian Andrzej Siewior authored
The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.

On AMD platforms the Out-of-band access is provided by Advanced Platform Management Link (APML), APML is a SMBus v2.0 compatible 2-wire processor client interface. APML is also referred as the sideband interface (SBI). APML is used to communicate with the Side-Band Remote Management Interface (SB-RMI) which provides Soft Mailbox messages to manage power consumption and power limits of the CPU socket. - This module add support to read power consumption, power limit & max power limit and write power limit. - To instantiate this driver on a Board Management Controller (BMC) connected to an AMD CPU with SB-RMI support, the i2c bus number would be the bus connected from the BMC to the CPU.

Linus Torvalds authored
Since commit 1b6b26ae ("pipe: fix and clarify pipe write wakeup logic") we have sanitized the pipe write logic, and would only try to wake up readers if they needed it. In particular, if the pipe already had data in it before the write, there was no point in trying to wake up a reader, since any existing readers must have been aware of the pre-existing data already. Doing extraneous wakeups will only cause potential thundering herd problems. However, it turns out that some Android libraries have misused the EPOLL interface, and expected "edge triggered" be to "any new write will trigger it". Even if there was no edge in sight. Quoting Sandeep Patil: "The commit 1b6b26ae ('pipe: fix and clarify pipe write wakeup logic') changed pipe write logic to wakeup readers only if the pipe was empty at the time of write. However, there are libraries that relied upon the older behavior for notification scheme similar to what's described in [1] One such library 'realm-core'[2] is used by numerous Android applications. The library uses a similar notification mechanism as GNU Make but it never drains the pipe until it is full. When Android moved to v5.10 kernel, all applications using this library stopped working. The library has since been fixed[3] but it will be a while before all applications incorporate the updated library" Our regression rule for the kernel is that if applications break from new behavior, it's a regression, even if it was because the application did something patently wrong. Also note the original report [4] by Michal Kerrisk about a test for this epoll behavior - but at that point we didn't know of any actual broken use case. So add the extraneous wakeup, to approximate the old behavior. [ I say "approximate", because the exact old behavior was to do a wakeup not for each write(), but for each pipe buffer chunk that was filled in. The behavior introduced by this change is not that - this is just "every write will cause a wakeup, whether necessary or not", which seems to be sufficient for the broken library use. ] It's worth noting that this adds the extraneous wakeup only for the write side, while the read side still considers the "edge" to be purely about reading enough from the pipe to allow further writes. See commit f467a6a6 ("pipe: fix and clarify pipe read wakeup logic") for the pipe read case, which remains that "only wake up if the pipe was full, and we read something from it".

Using page_objcgs_check() instead of page_objcgs() in memcg_slab_free_hook() to fix this bug.

SLUB uses page allocator for higher order allocations and update unreclaimable slab stat for such allocations. At the moment, the bulk free for SLUB does not share code with normal free code path for these type of allocations and have missed the stat update. So, fix the stat update by common code. The user visible impact of the bug is the potential of inconsistent unreclaimable slab stat visible through meminfo and vmstat.
