Andreas Kling a930877f31 Kernel: Mape quickmap functions VERIFY that MM lock is held ... The quickmap_page() and unquickmap_page() functions are used to map a single physical page at a kernel virtual address for temporary access. These use the per-CPU quickmap buffer in the page tables, and access to this is guarded by the MM lock. To prevent bugs, quickmap_page() should not *take* the MM lock, but rather verify that it is already held! This exposed two situations where we were using quickmap without holding the MM lock during page fault handling. This patch is forced to fix these issues (which is great!) :^)		2021-08-23 00:02:09 +02:00
