2007-10-16kprobes: support kretprobe blacklistMasami Hiramatsu
Introduce architecture dependent kretprobe blacklists to prohibit users from inserting return probes on the function in which kprobes can be inserted but kretprobes can not. This patch also removes "__kprobes" mark from "__switch_to" on x86_64 and registers "__switch_to" to the blacklist on x86-64, because that mark is to prohibit user from inserting only kretprobe.

2007-10-16x86: optimize page faults like all other achitectures and kill notifier cruftChristoph Hellwig
x86(-64) are the last architectures still using the page fault notifier cruft for the kprobes page fault hook. This patch converts them to the proper direct calls, and removes the now unused pagefault notifier bits aswell as the cruft in kprobes.c that was related to this mess. I know Andi didn't really like this, but all other architecture maintainers agreed the direct calls are much better and besides the obvious cruft removal a common way of dealing with kprobes across architectures is important aswell.

2007-10-11[AVR32] Don't use __builtin_xchg()Haavard Skinnemoen
The implementation of __builtin_xchg() in at least some versions of avr32 gcc is buggy. Rather than find out exactly which versions that have this bug, let's just avoid the problem altogether by implementing xchg() in inline assembly. Also, in most architectures, xchg() seems to imply a memory barrier, while the existing avr32 implementation did not. This patch also fixes that discrepancy.

2007-10-11[AVR32] Make dma_sync_*_for_cpu no-opsHaavard Skinnemoen
I don't think the dma_sync_*_for_cpu ever did anything useful. We flush the relevant cache lines when mapping the buffer or when calling dma_sync_*_for_device(), and the CPU isn't allowed to touch the buffer after that. In other words, if these functions actually have anything to flush from the caches, we're already in trouble. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-08-15[AVR32] Define mmiowb()Haavard Skinnemoen
Add empty definition of mmiowb() since some drivers need it. Uncached writes are strongly ordered on AVR32. They may be delayed if the dcache is busy doing a writeback, but AFAICT that's not what this macro is supposed to deal with, at least on UP systems. We might have to revisit this definition when a SMP-capable AVR32 CPU comes along, depending on how the busses and cache coherency stuff end up being implemented.

2007-08-15[AVR32] Fix bogus pte_page() definitionHaavard Skinnemoen
The current definition of pte_page() masks out valid bits from the physical address, causing vmalloc_to_page() to misbehave. This may lead to everything from mmap() silently accessing the wrong data to "invalid pte" errors dumped by the kernel. Also remove the now-unused definition of PTE_PHYS_MASK.

2007-07-18[AVR32] Fix atomic_add_unless() and atomic_sub_unless()Haavard Skinnemoen
These functions depend on "result" being initalized to 0, but "result" is not included as an input constraint to the inline assembly block following its initialization, only as an output constraint. Thus gcc thinks it doesn't need to initialize it, so result ends up undefined if the "unless" condition is true. This fixes an oops in sunrpc where the faulty atomics caused rpciod_up() to not start the workqueue as it should. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

Revert the optimization to prevent the RNDIS driver from crashing. Hopefully we'll figure something out later (it may be better to do the optimization in gcc.)

Several drivers shared between AT91 and AVR32 chips use cpu_is_xxx() to handle CPU-specific differences. Currently, such code needs to be inside #ifdef CONFIG_ARCH_AT91 because the macros don't exist on AVR32. By defining the same macros on both AT91 and AVR32, these #ifdefs can be eliminated. Since the macros will evaluate to a constant value for CPUs that aren't supported by the current architecture, any code that is only needed on AT91 will be optimized away on AVR32 and vice versa.

Add hooks to allow a paravirt implementation to track the lifetime of an mm. Paravirtualization requires three hooks, but only two are needed in common code. They are: arch_dup_mmap, which is called when a new mmap is created at fork arch_exit_mmap, which is called when the last process reference to an mm is dropped, which typically happens on exit and exec. The third hook is activate_mm, which is called from the arch-specific activate_mm() macro/function, and so doesn't need stub versions for other architectures. It's called when an mm is first used.

gcc 4.1 doesn't seem to like const variables as inline assembly outputs. Drop support for reading 64-bit values using get_user() so that we can use an unsigned long to hold the result regardless of the actual size. This should be safe since many architectures, including i386, doesn't support reading 64-bit values with get_user(). Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27avr32: remove unneeded cast in atomic.hMathieu Desnoyers
This int cast is superfluous since system.h cmpxchg already casts it in (typeof(*(ptr))). Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Use memcpy/memset in memcpy_{from,to}_io and memset_ioHaavard Skinnemoen
Using readb/writeb to implement these breaks NOR flash support. I can't see any reason why regular memcpy and memset shouldn't work. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Get rid of board_setup_fbmem()Haavard Skinnemoen
Since the core setup code takes care of both allocation and reservation of framebuffer memory, there's no need for this board- specific hook anymore. Replace it with two global variables, fbmem_start and fbmem_size, which can be used directly. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Simplify early handling of memory regionsHaavard Skinnemoen
Use struct resource to specify both physical memory regions and reserved regions and push everything into the same framework, including kernel code/data and initrd memory. This allows us to get rid of many special cases in the bootmem initialization and will also make it easier to implement more robust handling of framebuffer memory later.
