* m68k/amiga: Chip RAM - Always allocate from the start of memoryGeert Uytterhoeven2011-07-301-20/+15
| | | | | | | | | | | As of commit 5df1abdbd37af2ae317a1c5b5944173284dc55d6 ('m68k/amiga: Fix "debug=mem"'), "debug=mem" no longer uses amiga_chip_alloc_res(), so we can remove the hack to prefer memory at the safe end. This allows to simplify the code and make amiga_chip_alloc() just call amiga_chip_alloc_res() internally. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

| | | | | | | On m68k, it doesn't make sense to reserve memory for the PPC exception handlers, and APUS support is dead. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68k/amiga: Fix "debug=mem"Geert Uytterhoeven2011-01-231-9/+7
| | | | | | | | | | | | `debug=mem' on Amiga has been broken for a while. early_param() processing is done very/too early, i.e. before amiga_identify() / amiga_chip_init(), causing amiga_savekmsg_setup() not to find any Chip RAM. As we don't plan to free this memory anyway, just steal it from the initial Chip RAM memory block instead. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

* PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.
