The Hot-Pluggable field in SRAT suggests if the memory could be
hotplugged while the system is running. Print it as well when
parsing SRAT will help users to know which memory is hotpluggable.

This patch-set does some trivial fix and improving in ACPI code
for memory hotplug.
Patch 1,3,4 have been acked.
Tang Chen (4):
acpi: Print Hot-Pluggable Field in SRAT.
earlycpio.c: Fix the confusing comment of find_cpio_data().
acpi: Remove "continue" in macro INVALID_TABLE
for (...) {
...
if (...) {
ACPI_INVALID_TABLE()
continue;
}
...
}
Add the "continue" wherever the macro is called.
(For now, it is only called in acpi_initrd_override().)
The idea is from Yi
chieve this goal, we have to split all the following functions:
ACPICA:
acpi_tb_install_table()
acpi_tb_parse_root_table()
acpi_initialize_tables()
Linux acpi:
acpi_table_init()
acpi_boot_table_init()
Since ACPICA code is not just used by the Linux, so we should keep the ACPICA
side interface
acpi_tb_install_table() in acpi_tb_parse_root_table(). This will
keep acpi_tb_parse_root_table() works as before.

In the following patches, we need to call get_ramdisk_{image|size}()
to get initrd file's address and size. So make these two functions
global.
v1 -> v2:
As tj suggested, make these two function static inline in
arch/x86/include/asm/setup.h.
