From 573a446fc8ea4ca9be60b1db2091297da48d0a0d Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Wed, 3 Jul 2024 15:45:35 +0200 Subject: um: simplify and consolidate TLB updates The HVC update was mostly used to compress consecutive calls into one. This is mostly relevant for userspace where it is already handled by the syscall stub code. Simplify the whole logic and consolidate it for both kernel and userspace. This does remove the sequential syscall compression for the kernel, however that shouldn't be the main factor in most runs.
