[PATCH 2/3] mm/memory-failure: Check the mapcount of the precise page

A process may map only some of the pages in a folio, and might be missed if it maps the poisoned page but not the head page.

[PATCH] ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on action required events

by Shuai Xue

There are two major types of uncorrected error (UC) : - Action Required: The error is detected and the processor already consumes the memory. OS requires to take action (for example, offline failure page/kill failure thread) to recover this uncorrectable error. - Action Optional: The error is detected out of processor execution context. Some data in the memory are corrupted. But the data have not been consumed. OS is optional to take action to recover this uncorrectable error. For X86 platforms, we can easily distinguish between these two types based on the MCA Bank. While for arm64 platform, the memory failure flags for all UCs which severity are GHES_SEV_RECOVERABLE are set as 0, a.k.a, Action Optional now. If UC is detected by a background scrubber, it is obviously an Action Optional error. For other errors, we should conservatively regard them as Action Required. cper_sec_mem_err::error_type identifies the type of error that occurred if CPER_MEM_VALID_ERROR_TYPE is set. So, set memory failure flags as 0 for Scrub Uncorrected Error (type 14). Otherwise, set memory failure flags as MF_ACTION_REQUIRED.

[PATCH v2 05/16] serial: sc16is7xx: improve do/while loop in sc16is7xx_irq()

[PATCH v2 04/16] serial: sc16is7xx: remove obsolete loop in sc16is7xx_port_irq()

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Commit 834449872105 ("sc16is7xx: Fix for multi-channel stall") changed sc16is7xx_port_irq() from looping multiple times when there was still interrupts to serve. It simply changed the do {} while(1) loop to a do {} while(0) loop, which makes the loop itself now obsolete. Clean the code by removing this obsolete do {} while(0) loop.

[PATCH v2 03/16] serial: sc16is7xx: set safe default SPI clock frequency

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> 15 MHz is supported only by 76x variants. If the SPI clock frequency is not specified, use a safe default clock value of 4 MHz that is supported by all variants. Also use HZ_PER_MHZ macro to improve readability.
