[PATCH v2 0/2] x86/ioremap: clean up the mess in xxx_is_setup_data

[Baoquan He <bhe@redhat.com>]

Functions memremap_is_setup_data() and early_memremap_is_setup_data()
share completely the same process and handling, except of the
different memremap/unmap invocations. The code can be extracted and put
into a helper function __memremap_is_setup_data().

And parameter 'size' is unused in implementation of memremap_is_efi_data(),
memremap_is_setup_data and early_memremap_is_setup_data().

This patchset is made to clean them up. It sits on top of tip/x86/urgent
commit 8d9ffb2fe65a ("x86/mm: Fix a kdump kernel failure on SME system
when CONFIG_IMA_KEXEC=y")

v1->v2:
- Remove __init from helper __memremap_is_setup_data(), add __ref to
  helper suppress mismatch section warning.
- Merge the old patch 1 and 2 into one patch. 
  - Both are suggested by Tom during reviewing. Thanks to him.
