Rafael J. Wysocki	3e1e9002aa	x86: change static allocation of trampoline area ... Impact: fix trampoline sizing bug, save space While debugging a suspend-to-RAM related issue it occured to me that if the trampoline code had grown past 4 KB, we would have been allocating too little memory for it, since the 4 KB size of the trampoline is hardcoded into arch/x86/kernel/e820.c . Change that by making the kernel compute the trampoline size and allocate as much memory as necessary. Signed-off-by: Rafael J.

Yinghai Lu	a4c81cf684	x86: extend e820 ealy_res support 32bit ... move early_res related from e820_64.c to e820.c make edba detection to be done in head32.c remove smp_alloc_memory, because we have fixed trampoline address now.

Ingo Molnar	77ad386e59	x86: standalone trampoline code ... move the trampoline setup code out of smpboot.c - UP kernels can have suspend support too. Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-04-17 17:41:37 +02:00
