Subject: [PATCH] ix86: drop always empty .text..page_aligned section

Commit e44b7b7 ("x86: move suspend wakeup code to C") didn't care to
also eliminate the side effects that the earlier 4c49156 ("x86: make
arch/x86/kernel/acpi/wakeup_32.S use a separate") had, thus leaving a
now pointless, almost page size gap at the beginning of .text.
