ACPICA: Revert "Revert "Enable multi-byte EC transfers

This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA code. See ACPICA bugzilla 863.

ACPICA: Revert "Revert "Enable multi-byte EC transfers

This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA code. See ACPICA bugzilla 863.

ACPICA: Revert "Revert "Enable multi-byte EC transfers

This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA code. See ACPICA bugzilla 863.

ACPICA: Revert "Revert "Enable multi-byte EC transfers

This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA code. See ACPICA bugzilla 863.

ACPICA: Revert "Revert "Enable multi-byte EC transfers

This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA code. See ACPICA bugzilla 863.

Yes, that fix the problem.

Thanks for the report/bisection and test.

Len,
Please merge above code into then commit "ACPICA: Revert "Revert "Enable multi-byte EC transfers".

Actually, above code is in the ACPICA patch, but I made a mistake when generated the linuxized patch and above code was missed. Sorry for that.

Hi, Len

I found the root cause that t61 hangs.
T61 hangs at below code path:

start_kernel ->

    setup_arch ->
        acpi_boot_table_init ->
            acpi_blacklisted ->
                dmi_enable_osi_linux ->
                    dmi_enable_osi_linux ->
                        acpi_dmi_osi_linux -> (T61 hits the DMI table)
                            set_osi_linux ->
                                acpi_install_interface

acpi_install_interface needs to acquire a mutex, and the call to it hangs because ACPICA subsystem has not yet initialized at above call path.

Below patch fix it.
acpi_osi_setup only saves the OSI string(it does not call acpi_install_interface/acpi_remove_interface), and a later function acpi_osi_setup_late will handle the OSI string.
