In commit f01f17d3705b ("mm, vmstat: make quiet_vmstat lighter") the quiet_vmstat() function became asynchronous, in the sense that the vmstat work was still scheduled to run on the core when the function returned. For task isolation, we need a synchronous version of the function that guarantees

Task isolation wants to be able to verify that a remote core is running an isolated task to determine if it should generate a diagnostic, and also possibly interrupt it. This API returns a pointer to the task_struct of the task that was running on the specified core at the moment of the request;

[PATCH v16 09/13] arch/arm64: enable task isolation functionality

In do_notify_resume(), call task_isolation_start() for TIF_TASK_ISOLATION tasks. Add _TIF_TASK_ISOLATION to _TIF_WORK_MASK, and define a local NOTIFY_RESUME_LOOP_FLAGS to check in the loop, since we don't clear _TIF_TASK_ISOLATION in the loop. We tweak syscall_trace_enter() slightly to carry the

From: Francis Giraldeau This patch is a port of the task isolation functionality to the arm 32-bit architecture. The task isolation needs an additional thread flag that requires to change the entry assembly code to accept a bitfield larger than one byte. The

[PATCH 12/15] arm64: add a workaround for GNU gold with ARM64_MODULE_PLTS

[PATCH 10/15] arm64: disable ARM64_ERRATUM_843419 for clang LTO

CONFIG_CLANG_LTO depends on GNU gold, which can generate ADR_PREL_PG_HI21 relocations even with --fix-cortex-a53-843419. Since ARM64_ERRATUM_843419 disables kernel support for these relocations, disable the erratum when LTO is used. Signed-off-by: Sami Tolvanen ---
