2011-11-08m68k/amiga: Refactor amiints.cGeert Uytterhoeven1-51/+47
- Remove filename in comments, - Reorder functions so we no longer need forward declarations. Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-11-08m68k/irq: Remove obsolete IRQ_FLG_* usersGeert Uytterhoeven1-29/+0
The m68k core irq code stopped honoring these flags during the irq restructuring in 2006. Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-11-08m68k/irq: Rename {,__}m68k_handle_int()Geert Uytterhoeven2-13/+13
- Rename m68k_handle_int() to generic_handle_irq(), and drop the unneeded asmlinkage, - Rename __m68k_handle_int() to do_IRQ(). Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-11-08m68k/irq: Add m68k_setup_irq_controller()Geert Uytterhoeven2-3/+6
This is a wrapper around m68k_setup_irq_chip() that discards its dummy second parameter, to ease the future transition to genirq. Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-11-08m68k/irq: Switch irq_chip methods to "struct irq_data *data"Geert Uytterhoeven2-19/+22
Signed-off-by: Geert Uytterhoeven <[email protected]> Acked-by: Thomas Gleixner <[email protected]>
2011-11-08m68k/irq: Rename irq_controller to irq_chipGeert Uytterhoeven2-15/+12
Make it more similar to the genirq version: - Remove lock (unused as we don't do SMP anyway), - Prepend methods with irq_, - Make irq_startup() return unsigned int. Signed-off-by: Geert Uytterhoeven <[email protected]> Acked-by: Thomas Gleixner <[email protected]>
2011-07-30m68k/amiga: Chip RAM - Use lookup_resource()Geert Uytterhoeven1-11/+11
Replace a custom implementation (which doesn't lock the resource tree) by a call to lookup_resource() Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-07-30m68k/amiga: Chip RAM - Offset resource end by CHIP_PHYSADDRGeert Uytterhoeven1-1/+1
Technically, the end of Chip RAM should be offset by CHIP_PHYSADDR (which is zero). Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-07-30m68k/amiga: Chip RAM - Use resource_size() to fix off-by-one errorGeert Uytterhoeven1-1/+1

2011-07-30m68k/amiga: Chip RAM - Change chipavail to an atomic_tGeert Uytterhoeven1-6/+9
While the core resource handling code is safe, our global counter must still be protected against concurrent modifications. Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-07-30m68k/amiga: Chip RAM - Always allocate from the start of memoryGeert Uytterhoeven1-20/+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 <[email protected]>
2011-07-30m68k/amiga: Chip RAM - Convert from printk() to pr_*()Geert Uytterhoeven1-20/+8
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 <[email protected]>

2011-03-16m68k/amiga: Reclaim Chip RAM for PPC exception handlersGeert Uytterhoeven1-4/+0
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 <[email protected]>
2011-01-23m68k/amiga: Fix "debug=mem"Geert Uytterhoeven1-9/+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 <[email protected]>

The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable.

2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi1-0/+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.

2006-10-07[PATCH] m68k pt_regs fixesAl Viro3-25/+24
m68k_handle_int() split in two functions: __m68k_handle_int() takes pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs *. Places where we used to call m68k_handle_int() recursively with the same pt_regs have simply lost the second argument, the rest is switched to __m68k_handle_int(). The rest of patch is just dropping pt_regs * where needed. Signed-off-by: Al Viro <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
