acpi_memhotplug.c: don't allow to eject the memory device if it is being used

We eject the memory device even if it is in use.  It is very dangerous,
and it will cause the kernel to panic.

acpi_memhotplug.c: remove memory info from list before freeing it

We free info, but we forget to remove it from the list.  It will cause
unexpected problems when we access the list next time.

acpi_memhotplug.c: free memory device if acpi_memory_enable_device() failed

If acpi_memory_enable_device() fails, acpi_memory_enable_device() will
return a non-zero value, which means we fail to bind the memory device to
this driver.  So we should free memory device before
acpi_memory_device_add() returns.

cciss: fix incorrect scsi status reporting

Delete code which sets SCSI status incorrectly as it's already been set

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:

    0xffffffff815ffbd4 panic+0x01ca

    0xffffffff81d19341 x86_64_start_reservations+0x012c
    0xffffffff81d19449 x86_64_start_kernel+0x00fe

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().
