2021-06-30powerpc/64s/interrupt: clean up interrupt return labelsNicholas Piggin
Normal kernel-interrupt exits can get interrupt_return_srr_user_restart in their backtrace, which is an unusual and notable function, and it is part of the user-interrupt exit path, which is doubly confusing. Add non-local labels for both user and kernel interrupt exit cases to address this and make the user and kernel cases more symmetric. Also get rid of an unused label.

2021-06-30powerpc/64s/interrupt: preserve regs->softe for NMI interruptsNicholas Piggin
If an NMI interrupt hits in an implicit soft-masked region, regs->softe is modified to reflect that. This may not be necessary for correctness at the moment, but it is less surprising and it's unhelpful when debugging or adding checks. Make sure this is changed back to how it was found before returning.

2021-06-30powerpc/64s: add a table of implicit soft-masked addressesNicholas Piggin
Commit 9d1988ca87dd ("powerpc/64: treat low kernel text as irqs soft-masked") ends up catching too much code, including ret_from_fork, and parts of interrupt and syscall return that do not expect to be interrupts to be soft-masked. If an interrupt gets marked pending, and then the code proceeds out of the implicit soft-masked region it will fail to deal with the pending interrupt. Fix this by adding a new table of addresses which explicitly marks the regions of code that are soft masked. This table is only checked for interrupts that below __end_soft_masked, so most kernel interrupts will not have the overhead of the table search.

2021-06-30powerpc/64e: remove implicit soft-masking and interrupt exit restart logicNicholas Piggin
The implicit soft-masking to speed up interrupt return was going to be used by 64e as well, but it has not been extensively tested on that platform and is not considered ready. It was intended to be disabled before merge. Disable it for now. Most of the restart code is common with 64s, so with more correctness and performance testing this could be re-enabled again by adding the extra soft-mask checks to interrupt handlers and flipping exit_must_hard_disable().

2021-06-30powerpc/64s: fix hash page fault interrupt handlerNicholas Piggin
The early bad fault or key fault test in do_hash_fault() ends up calling into ___do_page_fault without having gone through an interrupt handler wrapper (except the initial _RAW one). This can end up calling local irq functions while the interrupt has not been reconciled, which will likely cause crashes and it trips up on a later patch that adds more assertions. pkey_exec_prot from selftests causes this path to be executed. There is no real reason to run the in_nmi() test should be performed before the key fault check. In fact if a perf interrupt in the hash fault code did a stack walk that was made to take a key fault somehow then running ___do_page_fault could possibly cause another hash fault causing problems. Move the in_nmi() test first, and then do everything else inside the regular interrupt handler function.

2021-06-30arm: extend pfn_valid to take into account freed memory map alignmentMike Rapoport

The code that frees unused memory map uses rounds start and end of the holes that are freed to MAX_ORDER_NR_PAGES to preserve continuity of the memory map for MAX_ORDER regions. Lots of core memory management functionality relies on homogeneity of the memory map within each pageblock which size may differ from MAX_ORDER in certain configurations. Although currently, for the architectures that use free_unused_memmap(), pageblock_order and MAX_ORDER are equivalent, it is cleaner to have common notation thought mm code. Replace MAX_ORDER_NR_PAGES with pageblock_nr_pages and update the comments to make it more clear why the alignment to pageblock boundaries is required.

2021-06-29drm/amd/display: Enabling eDP no power sequencing with DAL feature maskZhan Liu
[Why] Sometimes, DP receiver chip power-controlled externally by an Embedded Controller could be treated and used as eDP, if it drives mobile display. In this case, we shouldn't be doing power-sequencing, hence we can skip waiting for T7-ready and T9-ready." [How] Added a feature mask to enable eDP no power sequencing feature. To enable this, set 0x10 flag in amdgpu.dcfeaturemask on Linux command line.
