2020-11-05powerpc/8xx: Manage _PAGE_ACCESSED through APG bits in L1 entryChristophe Leroy4-66/+28
When _PAGE_ACCESSED is not set, a minor fault is expected. To do this, TLB miss exception ANDs _PAGE_PRESENT and _PAGE_ACCESSED into the L2 entry valid bit. To simplify the processing and reduce the number of instructions in TLB miss exceptions, manage it as an APG bit and get it next to _PAGE_GUARDED bit to allow a copy in one go. Then declare the corresponding groups as handling all accesses as user accesses. As the PP bits always define user as No Access, it will generate a fault.

2020-11-05powerpc/8xx: Always fault when _PAGE_ACCESSED is not setChristophe Leroy1-12/+2
The kernel expects pte_young() to work regardless of CONFIG_SWAP. Make sure a minor fault is taken to set _PAGE_ACCESSED when it is not already set, regardless of the selection of CONFIG_SWAP. This adds at least 3 instructions to the TLB miss exception handlers fast path. Following patch will reduce this overhead. Also update the rotation instruction to the correct number of bits to reflect all changes done to _PAGE_ACCESSED over time. Fixes: d069cb4373fe ("powerpc/8xx: Don't touch ACCESSED when no SWAP.") Fixes: 5f356497c384 ("powerpc/8xx: remove unused _PAGE_WRITETHRU") Fixes: e0a8e0d90a9f ("powerpc/8xx: Handle PAGE_USER via APG bits") Fixes: 5b2753fc3e8a ("powerpc/8xx: Implementation of PAGE_EXEC") Fixes: a891c43b97d3 ("powerpc/8xx: Prepare handlers for _PAGE_HUGE for 512k pages.")

2020-11-05drm/msm: Refcount submitsRob Clark4-12/+34
Before we remove dev->struct_mutex from the retire path, we have to deal with the situation of a submit retiring before the submit ioctl returns. To deal with this, ring->submits will hold a reference to the submit, which is dropped when the submit is retired. And the submit ioctl path holds it's own ref, which it drops when it is done with the submit. Also, add to submit list *after* getting/pinning bo's, to prevent badness in case the completed fence is corrupted, and retire_worker mistakenly believes the submit is done too early.
