* Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATIONRafael J. Wysocki2007-07-29
| | | | | | | | | Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid confusion (among other things, with CONFIG_SUSPEND introduced in the next patch). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* i386: do not restore reserved memory after hibernationRafael J. Wysocki2007-07-21
| | | | | | | | | | | | | | | | | | | | | On some systems the ACPI NVS area is located in the first 1 MB of RAM and it is overwritten by the i386 code during the restore after hibernation. This confuses the ACPI platform firmware that doesn't update the AC adapter status appropriately as a result (http://bugzilla.kernel.org/show_bug.cgi?id=7995). The solution is to register the reserved memory in the first 1 MB as 'nosave', so that swsusp doesn't touch it during the restore. Also, this has been done on x86_64 for a long time now, so this patch makes the i386 restore code behave like the x86_64 one. [akpm@linux-foundation.org: build fix] Signed-off-by: Rafael J.

* [PATCH] x86: fix amd64-agp aperture validationJan Beulich2007-05-02
| | | | | | | | | | | | Under CONFIG_DISCONTIGMEM, assuming that a !pfn_valid() implies all subsequent pfn-s are also invalid is wrong. Thus replace this by explicitly checking against the E820 map.

* [PATCH] i386: probe_roms() cleanupRene Herman2007-05-02
| | | | | | | | | | | | | | Remove the assumption that if the first page of a legacy ROM is mapped, it'll all be mapped. This'll also stop people reading this code from wondering if they're looking at a bug...

* [PATCH] compile error of register_memory()Yasunori Goto2006-12-22
| | | | | | | | | | | | | register_memory() becomes double definition in 2.6.20-rc1. It is defined in arch/i386/kernel/setup.c as static definition in 2.6.19. But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1. And same name function is defined in driver/base/memory.c too. So, it becomes cause of compile error of duplicate definition if memory hotplug option is on.
