The ACPI_PREEMPTION_POINT() logic was introduced in commit 8bd108d1 (ACPICA: add preemption point after each opcode parse). The follow up commits abe1dfab, 138d1569, c084ca70 tried to fix the preemption logic back and forth, but nobody noticed that the usage of in_atomic_preempt_off() in that context is wrong. The check which guards the call of cond_resched() is: if (!in_atomic_preempt_off() && !irqs_disabled()) in_atomic_preempt_off() is not intended for general use as the comment above the macro definition clearly says: * Check whether we were atomic before we did preempt_disable(): * (used by the scheduler, *after* releasing the kernel lock) On a CONFIG_PREEMPT=n kernel the usage of in_atomic_preempt_off() works by accident, but with CONFIG_PREEMPT=y it's just broken. The whole purpose of the ACPI_PREEMPTION_POINT() is to reduce the latency on a CONFIG_PREEMPT=n kernel, so make ACPI_PREEMPTION_POINT() depend on CONFIG_PREEMPT=n and remove the in_atomic_preempt_off() check.

The current kfifo scatterlist implementation will not work with chained scatterlists. It assumes that struct scatterlist arrays are allocated contiguously, which is not the case when chained scatterlists (struct sg_table) are in use. Signed-off-by:

Stefani Seibold authored
There are different types of a fifo which can not handled in C without a lot of overhead. So i decided to write the API as a set of macros, which is the only way to do a kind of template meta programming without C++. This macros handles the different types of fifos in a transparent way. There are a lot of benefits: - Compile time handling of the different fifo types - Better performance (a save put or get of an integer does only generate 9 assembly instructions on a x86) - Type save - Cleaner interface, the additional kfifo_..._rec() functions are gone - Easier to use - Less error prone - Different types of fifos: it is now possible to define a int fifo or any other type. See below for an example. - Smaller footprint for none byte type fifos - No need of creating a second hidden variable, like in the old DEFINE_KFIFO The API was not changed. There are now real in place fifos where the data space is a part of the structure. The fifo needs now 20 byte plus the fifo space. Dynamic assigned or allocated create a little bit more code. Most of the macros code will be optimized away and simple generate a function call. Only the really small one generates inline code. Additionally you can now create fifos for any data type, not only the "unsigned char" byte streamed fifos. There is also a new kfifo_put and kfifo_get function, to handle a single element in a fifo. This macros generates inline code, which is lit bit larger but faster. I know that this kind of macros are very sophisticated and not easy to maintain. But i have all tested and it works as expected. I analyzed the output of the compiler and for the x86 the code is as good as hand written assembler code. For the byte stream fifo the generate code is exact the same as with the current kfifo implementation. For all other types of fifos the code is smaller before, because the interface is easier to use. The main goal was to provide an API which is very intuitive, save and easy to use. So linux will get now a powerful fifo API which provides all what a developer needs. This will save in the future a lot of kernel space, since there is no need to write an own implementation. Most of the device driver developers need a fifo, and also deep kernel development will gain benefit from this API. Here are the results of the text section usage: Example 1: kfifo_put/_get kfifo_in/out current kfifo dynamic allocated 0x000002a8 0x00000291 0x00000299 in place 0x00000291 0x0000026e 0x00000273 kfifo.c new old text section size 0x00000be5 0x000008b2 As you can see, kfifo_put/kfifo_get creates a little bit more code than kfifo_in/kfifo_out, but it is much faster (the code is inline). The code is complete hand crafted and optimized. The text section size is as small as possible. You get all the fifo handling in only 3 kb. This includes type safe fix size records, dynamic records and DMA handling. This should be the final version. All requested features are implemented. Note: Most features of this API doesn't have any users. All functions which are not used in the next 9 months will be removed. So, please adapt your drivers and other sources as soon as possible to the new API and post it. This are the features which are currently not used in the kernel: kfifo_to_user() kfifo_from_user() kfifo_dma_....() macros kfifo_esize() kfifo_recsize() kfifo_put() kfifo_get() The fixed size record elements, exclude "unsigned char" fifo's and the variable size records fifo's This patch: User of the kernel fifo should never bypass the API and directly access the fifo structure. Otherwise it will be very hard to maintain the API. Signed-off-by: -

copy_to/from_user() returns the number of bytes remaining to be copied. It never returns a negative value. The correct return code is -EFAULT and not -EIO. All the callers check for non-zero returns so that's Ok, but the return code is passed to the user so we should fix this. Signed-off-by:

There are a few issues with the exception based WARN implementation in lib/bug.c: - Inconsistent printk flags. The "cut here" line is printed at KERN_EMERG, so the console and all logged in users see the single line: ------------[ cut here ]------------ for each WARN. Fix this so we print everything at KERN_WARNING to match the kernel/panic.c version. - The lib/bug.c WARN would print "Badness at". Change it to match the kernel/panic.c version which prints "WARNING: at". - Print the list of modules, similar to kernel/panic.c of modules, similar to kernel/panic.c [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

To keep panic_timeout accuracy when running under a hypervisor, the current implementation only spins on long time (1 second) calls to mdelay. That brings a good effect, but the problem is the keyboard LEDs don't blink at all on that situation. This patch changes to call to panic_blink_enter() between every mdelay and keeps blinking in spite of long spin timer mode. The time to call to mdelay is now 100ms. Even this change will keep panic_timeout accuracy enough when running under a hypervisor. Signed-off-by:

Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

This driver is the only user of dma_is_consistent(). We plan to remove this API. The driver uses the API in the following way: BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment()); The above code tries to see if L1_CACHE_BYTES is greater than dma_get_cache_alignment() on sysmtes that can not allocate coherent memory (some old systems can't). James Bottomley exmplained that this is necesary because the driver packs the set of mailboxes into a single coherent area and separates the different usages by a L1 cache stride. So it's fatal if the dma He also pointed out that we can kill this checking because we don't hit this BUG_ON on all architectures that actually use the driver.

dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue. Signed-off-by:

Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto). Signed-off-by:

alloc_pidmap() calculates max_scan so that if the initial offset != 0 we inspect the first map->page twice. This is correct, we want to find the unused bits < offset in this bitmap block. Add the comment. But it doesn't make any sense to stop the find_next_offset() loop when we are looking into this map->page for the second time. We have already already checked the bits >= offset during the first attempt, it is fine to do this again, no matter if we succeed this time or not. Remove this hard-to-understand code. It optimizes the very unlikely case when we are going to fail, but slows down the more likely case. Signed-off-by:
