When hot-adding/removing memory, sync_global_pgds() is called for

We need to allocate boot_params early and clear it before copy
setup_header to it.
So kernel will not call sanitize_boot_params() to overwrite new

We should modify boot_params later instead of touch temp buf too early.

remove_pagetable() gets start argument and passes the argument to
sync_global_pgds(). In this case, the argument must not be modified.

For hot-added PCIe ports, it always generates a warning message on x86
platforms when binding to portdrv as:
"device [8086:0e0b] has invalid IRQ; check vendor BIOS".
It's due to that we check pci_dev->irq before actually allocating IRQ
for the PCI device:
if (!dev->irq && dev->pin)

This is just for the I2C tunnel feature, right? If so, I think this

We would like to have a chance to work on your website and get it positioned

The GPE APIs should be invoked inside of an IRQ context GPE handler or in
the task context with a driver provided lock held. This driver provided
lock should be safe to be held in the GPE handler by the driver.
While currently we cannot do this, thus we can only use the GPE APIs for
limitted cases
This patch reduces indent divergences first in order to reduce human

The stale GPE indication is not a problem. Drivers should always check the
underlying hardware status and be ready to handle invalid status.
The GPE clearing implemented in acpi_ev_enable_gpe() on the contrary
introduces issues for acpi_enable_gpe() logic. When the usage count of GPE is
increased

Developers really don't need to translate EC commands in mind. This patch
adds detailed debugging information for the EC commands.
The address can be found in the follow-up sequential EC_DATA(W) accesses,
thus this patch also removes some of the redundant address information.

This patch adds facility to test future EC modification.
All EC commits should enable TEST_HOTPLUG, and try a build/boot test.
Since EC is currently a built-in module, this is the only mean for us to
test the hotplug code.

This patch deploys the following GPE handling model:
1. acpi_enable_gpe()/acpi_disable_gpe():
This set of APIs are used for EC usage reference counting.
2. acpi_set_gpe(ACPI_GPE_ENABLE)/acpi_set_gpe(ACPI_GPE_DISABLE):
This set of APIs are used for preventing GPE storm.
For the EC driver,
The back port result of a divergence fix that the origianlly_enabled check

This patchset is based on the previous ACPI/EC bug fixes series.
This patchset has fixed the following issues:
1. Enables the ideal GPE handling model.
The ideal GPE handling model should be able to handle the following
cases:
1. When upper layers (the users of the driver) submit requests
This can help to reduce source code differences between Linux and ACPICA
upstream. Further driver cleanups also require these APIs to eliminate GPE
storms.
1. acpi_set_gpe(): An API that driver should invoke in the case it wants
to disable/enable IRQ without honoring the referenc
