2021-02-26zsmalloc: account the number of compacted pages correctlyRokudo Yan
There exists multiple path may do zram compaction concurrently. 1. auto-compaction triggered during memory reclaim 2. userspace utils write zram<id>/compaction node So, multiple threads may call zs_shrinker_scan/zs_compact concurrently. But pages_compacted is a per zsmalloc pool variable and modification of the variable is not serialized(through under class->lock). There are two issues here: 1. the pages_compacted may not equal to total number of pages freed(due to concurrently add). 2. zs_shrinker_scan may not return the correct number of pages freed(issued by current shrinker). The fix is simple: 1. account the number of pages freed in zs_compact locally. 2. use actomic variable pages_compacted to accumulate total number.

2021-02-26virtio-mem: check against mhp_get_pluggable_range() which memory we can hotplugDavid Hildenbrand
Right now, we only check against MAX_PHYSMEM_BITS - but turns out there are more restrictions of which memory we can actually hotplug, especially om arm64 or s390x once we support them: we might receive something like -E2BIG or -ERANGE from add_memory_driver_managed(), stopping device operation. So, check right when initializing the device which memory we can add, warning the user. Try only adding actually pluggable ranges: in the worst case, no memory provided by our device is pluggable. In the usual case, we expect all device memory to be pluggable, and in corner cases only some memory at the end of the device-managed memory region to not be pluggable.

2021-02-26drivers/base/memory: don't store phys_device in memory blocksDavid Hildenbrand
No need to store the value for each and every memory block, as we can easily query the value at runtime. Reshuffle the members to optimize the memory layout. Also, let's clarify what the interface once was used for and why it's legacy nowadays. "phys_device" was used on s390x in older versions of lsmem[2]/chmem[3], back when they were still part of s390x-tools. They were later replaced by the variants in linux-utils. For example, RHEL6 and RHEL7 contain lsmem/chmem from s390-utils. RHEL8 switched to versions from util-linux on s390x [4]. "phys_device" was added with sysfs support for memory hotplug in commit 3947be1969a9 ("[PATCH] memory hotplug: sysfs and add/remove functions") in 2005. It always returned 0. s390x started returning something != 0 on some setups (if sclp.rzm is set by HW) in 2010 via commit 57b552ba0b2f ("memory hotplug/s390: set phys_device"). For s390x, it allowed for identifying which memory block devices belong to the same storage increment (RZM). Only if all memory block devices comprising a single storage increment were offline, the memory could actually be removed in the hypervisor. Since commit e5d709bb5fb7 ("s390/memory hotplug: provide memory_block_size_bytes() function") in 2013 a memory block device spans at least one storage increment - which is why the interface isn't really helpful/used anymore (except by old lsmem/chmem tools). There were once RFC patches to make use of "phys_device" in ACPI context; however, the underlying problem could be solved using different interfaces [1].

2021-02-26drm/compat: Clear bounce structuresDaniel Vetter
Some of them have gaps, or fields we don't clear. Native ioctl code does full copies plus zero-extends on size mismatch, so nothing can leak. But compat is more hand-rolled so need to be careful. None of these matter for performance, so just memset. Also I didn't fix up the CONFIG_DRM_LEGACY or CONFIG_DRM_AGP ioctl, those are security holes anyway.

2021-02-25net: phy: micrel: set soft_reset callback to genphy_soft_reset for KSZ8081Christian Melki
Following a similar reinstate for the KSZ9031. Older kernels would use the genphy_soft_reset if the PHY did not implement a .soft_reset. Bluntly removing that default may expose a lot of situations where various PHYs/board implementations won't recover on various changes. Like with this implementation during a 4.9.x to 5.4.x LTS transition. I think it's a good thing to remove unwanted soft resets but wonder if it did open a can of worms? Atleast this fixes one iMX6 FEC/RMII/8081 combo.

2021-02-25dma-buf: heaps: Fix the name used when exporting dmabufs to be the actual ↵John Stultz
heap name By default dma_buf_export() sets the exporter name to be KBUILD_MODNAME. Unfortunately this may not be identical to the string used as the heap name (ie: "system" vs "system_heap"). This can cause some minor confusion with tooling, and there is the future potential where multiple heap types may be exported by the same module (but would all have the same name). So to avoid all this, set the exporter exp_name to the heap name.
