[PATCH] Optimize D-cache alias handling on fork

2006-12-13T17:27:08Z

Virtually index, physically tagged cache architectures can get away without cache flushing when forking. This patch adds a new cache flushing function flush_cache_dup_mm(struct mm_struct *) which for the moment I've implemented to do the same thing on all architectures except on MIPS where it's a no-op.

[PATCH] tty: preparatory structures for termios revamp

2006-12-08T16:28:56Z

In order to sort out our struct termios and add proper speed control we need to separate the kernel and user termios structures. Glibc is fine but the other libraries rely on the kernel exported struct termios and we need to extend this without breaking the ABI/API To do so we add a struct ktermios which is the kernel view of a termios structure and overlaps the struct termios with extra fields on the end for now. (That limitation will go away in later patches). Some platforms (eg alpha) planned ahead and thus use the same struct for both, others did not. This just adds the structures but does not use them, it seems a sensible splitting point for bisect if there are compile failures (not that I expect them) Signed-off-by: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Pass struct dev pointer to dma_cache_sync()

2006-12-07T16:39:41Z

Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync to take a struct device pointer as first argument and fix all its callers to pass it. Signed-off-by: Ralf Baechle Cc: James Bottomley Cc: "David S.

[PATCH] Add struct dev pointer to dma_is_consistent()

2006-12-07T16:39:41Z

dma_is_consistent() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_is_consistent to take a struct device pointer as first argument and fix the sole caller to pass it. Signed-off-by: Ralf Baechle Cc: James Bottomley Cc: "David S.

[PATCH] remove kernel syscalls

2006-12-07T16:39:37Z

The last thing we agreed on was to remove the macros entirely for 2.6.19, on all architectures. Unfortunately, I think nobody actually _did_ that, so they are still there. [akpm@osdl.org: x86_64 fix] Cc: David Woodhouse Cc: Greg Schafer Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[NET]: Alpha checksum annotations and cleanups.

2006-12-03T05:23:01Z

* sanitize prototypes and annotate * kill useless access_ok() in csum_partial_copy_from_user() (the only caller checks it already). * do_csum_partial_copy_from_user() is not needed now * replace htons(len) with len << 8 - they are the same wrt checksums on little-endian.

Driver core: add dev_archdata to struct device

2006-12-01T22:52:01Z

Add arch specific dev_archdata to struct device Adds an arch specific struct dev_arch to struct device. This enables architecture to add specific fields to every device in the system, like DMA operation pointers, NUMA node ID, firmware specific data, etc...

[PATCH] Consolidate check_signature

2006-10-11T18:14:23Z

There's nothing arch-specific about check_signature(), so move it to . Use a cross between the Alpha and i386 implementations as the generic one. Signed-off-by: Matthew Wilcox Acked-by: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] alpha pt_regs cleanups: machine_check()

[PATCH] alpha pt_regs cleanups: device_interrupt

2006-10-08T19:32:35Z

callers of ->device_interrupt() do set_irq_regs() now; pt_regs argument removed, remaining uses of regs in instances of ->device_interrupt() are switched to get_irq_regs() and will be gone in the next patch. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds
