Since introducing the ability to have large folios in the page cache, it's been possible to have a hwpoisoned tail page returned from the fault handler. We handle this situation poorly; failing to remove the affected page from use. This isn't a minimal patch to fix it, it's a full conversion of all the code surrounding it. This patch (of 6): invalidate_inode_page() does very little beyond calling mapping_evict_folio(). Move the check for mapping being NULL into mapping_evict_folio() and make it available to the rest of the MM for use in the next few patches.

[PATCH 16/20] drm/amd/display: Fix encoder disable logic

by Alex Hung

From: Nicholas Susanto <nicholas.susanto(a)amd.com> [WHY] DENTIST hangs when OTG is off and encoder is on. We were not disabling the encoder properly when switching from extended mode to external monitor only. [HOW] Disable the encoder using an existing enable/disable fifo helper instead of enc35_stream_encoder_enable.

[PATCH 14/20] drm/amd/display: Change the DMCUB mailbox memory location from FB to inbox

by Alex Hung

From: Lewis Huang <lewis.huang(a)amd.com> [WHY] Flush command sent to DMCUB spends more time for execution on a dGPU than on an APU. This causes cursor lag when using high refresh rate mouses. [HOW] 1. Change the DMCUB mailbox memory location from FB to inbox. 2. Only change windows memory to inbox.
