Bug description:
Additional AWS-specific and mainline patches are required to support
hibernation across the various types of AWS instances.
The following patch sets for linux-aws-xenial and linux-aws-bionic
provide the necessary functionality, and should only impact the
hibernation and resume paths.
[linux-aws-xenial]
UBUNTU SAUCE [aws]: block: xen-blkfront: consider new dom0 features on restore
UBUNTU SAUCE [aws]: ACPICA: Enable sleep button on ACPI legacy wake
UBUNTU SAUCE [aws]: xen: restore pirqs on resume from hibernation.
UBUNTU SAUCE [aws]: xen: Only restore the ACPI SCI interrupt in
xen_restore_pirqs.
radix-tree: delete radix_tree_locate_item()
mm: rid swapoff of quadratic complexity
sched/wait: Fix abort_exclusive_wait(), it should pass TASK_NORMAL to
wake_up()
sched/wait: Avoid abort_exclusive_wait() in ___wait_event()
sched/wait: Avoid abort_exclusive_wait() in __wait_on_bit_lock()
sched/wait: Introduce init_wait_entry()
sched/wait: Standardize wait_bit_queue naming
sched/wait: Introduce wait_var_event()
mm: swapoff: shmem_unuse() stop eviction without igrab()
UBUNTU SAUCE [aws]: mm: aggressive swapoff
UBUNTU SAUCE [aws]: PM / hibernate: make sure pm_async is always disabled
NVMe: Allow request merges
PM / hibernate: Do not free preallocated safe pages during image restore
PM / hibernate: Recycle safe pages after image restoration
PM / hibernate: Simplify mark_unsafe_pages()
UBUNTU: [Config] aws: disable CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS
UBUNTU SAUCE [aws] PM / hibernate: set image_size to total RAM size by default
UBUNTU SAUCE [aws] PM / hibernate: reduce memory pressure during image writing
UBUNTU SAUCE [aws] mm, page_alloc: disable fair zone allocation policy on
hibernate
[linux-aws-bionic]
UBUNTU SAUCE [aws]: block: xen-blkfront: consider new dom0 features on restore
UBUNTU SAUCE [aws]: ACPICA: Enable sleep button on ACPI legacy wake
UBUNTU SAUCE [aws]: xen: restore pirqs on resume from hibernation.
UBUNTU SAUCE [aws]: xen: Only restore the ACPI SCI interrupt in
xen_restore_pirqs.
mm: rid swapoff of quadratic complexity
sched/wait: Introduce wait_var_event()
mm: swapoff: shmem_unuse() stop eviction without igrab()
UBUNTU SAUCE [aws]: mm: aggressive swapoff
netlink: Don't shift on 64 for ngroups
[linux-aws-edge-bionic]
UBUNTU SAUCE [aws]: xen: Only restore the ACPI SCI interrupt in
xen_restore_pirqs.
UBUNTU SAUCE [aws]: xen: restore pirqs on resume from hibernation.
UBUNTU SAUCE [aws]: block: xen-blkfront: consider new dom0 features on restore
UBUNTU SAUCE [aws]: ACPICA: Enable sleep button on ACPI legacy wake
UBUNTU SAUCE [aws]: PM / hibernate: set image_size to 0 by default
UBUNTU SAUCE [aws]: PM / hibernate: make sure pm_async is always disabled
UBUNTU SAUCE [aws]: mm: swap: improve swap readahead heuristic
UBUNTU SAUCE [aws] PM / hibernate: reduce memory pressure during image writing
PM / hibernate: memory_bm_find_bit(): Tighten node optimisation
mm: rid swapoff of quadratic complexity
mm: refactor swap-in logic out of shmem_getpage_gfp
