2011-07-30m68k/amiga: Chip RAM - Use lookup_resource()Geert Uytterhoeven
Replace a custom implementation (which doesn't lock the resource tree) by a call to lookup_resource() Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-07-30m68k/amiga: Chip RAM - Offset resource end by CHIP_PHYSADDRGeert Uytterhoeven
Technically, the end of Chip RAM should be offset by CHIP_PHYSADDR (which is zero). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-07-30m68k/amiga: Chip RAM - Use resource_size() to fix off-by-one errorGeert Uytterhoeven

2011-07-30m68k/amiga: Chip RAM - Change chipavail to an atomic_tGeert Uytterhoeven
While the core resource handling code is safe, our global counter must still be protected against concurrent modifications. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-07-30m68k/amiga: Chip RAM - Always allocate from the start of memoryGeert Uytterhoeven
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>
2011-07-30m68k/amiga: Chip RAM - Convert from printk() to pr_*()Geert Uytterhoeven
and fix a few formattings: - resource sizes are now resource_size_t, use %pR to make it future proof, - use %lu for unsigned long. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2011-03-16m68k/amiga: Reclaim Chip RAM for PPC exception handlersGeert Uytterhoeven
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>
2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi
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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
