2007-10-16During VM oom condition, kill all threads in process groupWill Schmidt1-1/+1
We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or be otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread.

2007-10-14kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg2-6/+4
The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

2007-08-27[XTENSA] Add support for cache-aliasingChris Zankel7-290/+624
Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.

2007-08-27[XTENSA] Add support for executable/non-executable feature in the mmuChris Zankel1-14/+28
Newer processor versions starting with Xtensa6/LX2 support an 'executable' bit for memory pages. This bit replaces the 'valid' bit, so it must be always set to one for older processor versions. To mark a page invalid, we now set the cache-attributes to b11, which is backward compatible. Signed-off-by: Chris Zankel <chris@zankel.net>

2007-07-19define new percpu interface for shared dataFenghua Yu1-4/+1
per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

2007-05-09rename thread_info to stackRoman Zippel1-1/+1
This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare2-2/+0
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining.

2007-05-02[PATCH] x86: Allow percpu variables to be page-alignedJeremy Fitzhardinge1-1/+1
Let's allow page-alignment in general for per-cpu data (wanted by Xen, and Ingo suggested KVM as well). Because larger alignments can use more room, we increase the max per-cpu memory to 64k rather than 32k: it's getting a little tight.

2007-04-25[SK_BUFF]: Introduce skb_reset_mac_header(skb)Arnaldo Carvalho de Melo1-1/+1
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

* Split the implementation-agnostic stuff in separate files. * Make sure that targets using non-default request_irq() pull kernel/irq/devres.o * Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive; allow architectures to turn them off (we needed these symbols anyway for dependencies of quite a few drivers). * protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.

2007-02-11[PATCH] optional ZONE_DMA: introduce CONFIG_ZONE_DMAChristoph Lameter1-0/+4
This patch simply defines CONFIG_ZONE_DMA for all arches. We later do special things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work without ZONE_DMA. CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture handles ISA DMA. First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch needs ZONE_DMA because ISA DMA devices are supported. We can catch this in mm/Kconfig and do not need to modify arch code. Second, arches may use ZONE_DMA in an unknown way. We set CONFIG_ZONE_DMA for all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards compatibility. The arches may later undefine ZONE_DMA if their arch code has been verified to not depend on ZONE_DMA.
