[Qemu-devel] [PATCH 1/3] hw/acpi: acpi_pm1_cnt_init(): take "disable_s3" and "disable_s4"

[Laszlo Ersek <lersek@redhat.com>]

This patch only modifies the function prototype and updates all chipset
code that calls acpi_pm1_cnt_init() to pass in their own disable_s3 and
disable_s4 settings. vt82c686 is assumed to be fixed "S3 and S4 enabled".
