The use of defined() on arrays and hashes has been deprecated since perl
5.6, but until 5.17.6 it only warned on lexicals, not package globals.

prctl: remove redunant assignment of "error" to zero
Just setting the "error" to error number is enough on failure and It
doesn't require to set "error" variable to zero in each switch case, since
it was already initialized with zero. And also removed return 0 in switch
case with break statement

acpi_memhotplug.c: auto bind the memory device which is hotplugged before the driver is loaded
If the memory device is hotplugged before the driver is loaded, the user

user cannot bind it by hand after the driver is loaded. This patch
introduces a new feature to bind such device when the driver is being
loaded.

acpi_memhotplug.c: bind the memory device when the driver is being loaded
We had introduced acpi_hotmem_initialized to avoid strange add_memory fail

device should be bound when the driver is being loaded. Remove
acpi_hotmem_initialized to allow that the device can be bound when the
driver is being loaded.

If acpi_memory_enable_device() fails, acpi_memory_enable_device() will

this driver. So we should free memory device before

pcdp: use early_ioremap/early_iounmap to access pcdp table
efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP EFI
system table and setup an early console for printk output. The routine
uses ioremap/iounmap to setup access to the HCDP/PCDP table information.
The call to ioremap is happening early in the boot process which leads to
a panic on x86_64 systems:
This patch replaces the calls to ioremap/iounmap in
efi_setup_pcdp_console() with calls to early_ioremap/early_iounmap which
can be called during early boot.
This patch was tested on an x86_64 prototype system which uses the
HCDP/PCDP table for early console setup.

mm: fix wrong argument of migrate_huge_pages() in soft_offline_huge_page()
a6bc32b899223 ("mm: compaction: introduce sync-light migration for use by
compaction") changed the declaration of migrate_pages() and
migrate_huge_pages(). But it missed changing the argument of
migrate_huge_pages() in soft_offline_huge_page(). In this case, we should
call migrate_huge_pages() with MIGRATE_SYNC.
Additionally, there is a mismatch between type the of argument and the
function declaration for migrate_pages().
