* x86, realmode: Move ACPI wakeup to unified realmode codeJarkko Sakkinen2012-05-081-83/+0
| | | | | | | | | | | | | Migrated ACPI wakeup code to the real-mode blob. Code existing in .x86_trampoline can be completely removed. Static descriptor table in wakeup_asm.S is courtesy of H. Peter Anvin. Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@intel.com> Link: http://lkml.kernel.org/r/1336501366-28617-7-git-send-email-jarkko.sakkinen@intel.com Cc: Rafael J.

* x86, trampoline: Common infrastructure for low memory trampolinesH. Peter Anvin2011-02-171-4/+11
| | | | | | | | | | | | | | | | | | | | Common infrastructure for low memory trampolines. This code installs the trampolines permanently in low memory very early. It also permits multiple pieces of code to be used for this purpose. This code also introduces a standard infrastructure for computing symbol addresses in the trampoline code. The only change to the actual SMP trampolines themselves is that the 64-bit trampoline has been made reusable -- the previous version would overwrite the code with a status variable; this moves the status variable to a separate location.

* x86: use _types.h headers in asm where availableJeremy Fitzhardinge2009-02-131-1/+1
| | | | | | | In general, the only definitions that assembly files can use are in _types.S headers (where available), so convert them. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

* x86: remove misleading comments in trampoline_*.SPavel Machek2008-02-041-6/+1
| | | | | | | | | Both trampolines actually *do* set up stack. (Is the "we jump into compressed/head.S" comment still true?) Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
