2008-03-24mm: fix boundary checking in free_bootmem_coreYinghai Lu1-6/+19
With numa enabled, some callers could have a range of memory on one node but try to free that on other node. This can cause some pages to be freed wrongly. For example: when we try to allocate 128g boot ram early for gart/swiotlb, and free that range later so gart/swiotlb can get some range afterwards. With this patch, we don't need to care which node holds the range, just loop to call free_bootmem_node for all online nodes. This patch makes free_bootmem_core() more robust by trimming the sidx and eidx according the ram range that the node has. And make the free_bootmem_core handle this out of range case. We could use bdata_list to make sure the range can be freed for sure. So next time, we don't need to loop online nodes and could use free_bootmem directly.

2008-03-24SVCRDMA: Use only 1 RDMA read scatter entry for iWARP adaptersRoland Dreier1-2/+0
The iWARP protocol limits RDMA read requests to a single scatter entry. NFS/RDMA has code in rdma_read_max_sge() that is supposed to limit the sge_count for RDMA read requests to 1, but the code to do that is inside an #ifdef RDMA_TRANSPORT_IWARP block. In the mainline kernel at least, RDMA_TRANSPORT_IWARP is an enum and not a preprocessor #define, so the #ifdef'ed code is never compiled. In my test of a kernel build with -j8 on an NFS/RDMA mount, this problem eventually leads to trouble starting with: svcrdma: Error posting send = -22 svcrdma : RDMA_READ error = -22 and things go downhill from there. The trivial fix is to delete the #ifdef guard. The check seems to be a remnant of when the NFS/RDMA code was not merged and needed to compile against multiple kernel versions, although I don't think it ever worked as intended. In any case now that the code is upstream there's no need to test whether the RDMA_TRANSPORT_IWARP constant is defined or not. Without this patch, my kernel build on an NFS/RDMA mount using NetEffect adapters quickly and 100% reproducibly failed with an error like: ld: final link failed: Software caused connection abort With the patch applied I was able to complete a kernel build on the same setup. (Tom Tucker says this is "actually an _ancient_ remnant when it had to compile against iWARP vs. non-iWARP enabled OFA trees.")

2008-03-24x86-32: Pass the full resource data to ioremap()Linus Torvalds4-10/+10
It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.

2008-03-24[POWERPC] Fix Oops with TQM5200 on TQM5200Anatolij Gustschin1-2/+2
The "bestcomm-core" driver defines its of_match table as follows static struct of_device_id mpc52xx_bcom_of_match[] = { { .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", }, { .type = "dma-controller", .compatible = "mpc5200-bestcomm", }, {}, }; so while registering the driver, the driver's probe function won't be called, because the device tree node doesn't have a device_type property. Thus the driver's bcom_engine structure won't be allocated. Referencing this structure later causes observed Oops. Checking bcom_eng pointer for NULL before referencing data pointed by it prevents oopsing, but fec driver still doesn't work (because of the lost bestcomm match and resulted task allocation failure). Actually the compatible property exists and should match and so the fec driver should work. This removes .type = "dma-controller" from the bestcomm driver's mpc52xx_bcom_of_match table to solve the problem.

2008-03-24[POWERPC] Don't use 64k pages for ioremap on pSeriesPaul Mackerras1-3/+8
On pSeries, the hypervisor doesn't let us map in the eHEA ethernet adapter using 64k pages, and thus the ehea driver will fail if 64k pages are configured. This works around the problem by always using 4k pages for ioremap on pSeries (but not on other platforms). A better fix would be to check whether the partition could ever have an eHEA adapter, and only force 4k pages if it could, but this will do for 2.6.25. This is based on an earlier patch by Tony Breeds. Signed-off-by: Paul Mackerras <paulus@samba.org>

PNP_MAX_MEM and PNP_MAX_PORT are mainly used to size tables of PNP device resources. In 2.6.24, we increased their values to accomodate ACPI devices that have many resources: 2.6.23 2.6.24 ------ ------ PNP_MAX_MEM 4 12 PNP_MAX_PORT 8 40 However, ISAPNP also used these constants as the size of parts of the logical device register set. This register set is fixed by hardware, so increasing the constants meant that we were reading and writing unintended parts of the register set. This patch changes ISAPNP to use the correct register set sizes (the same values we used prior to 2.6.24).

2008-03-22[TCP]: Let skbs grow over a page on fast peersHerbert Xu1-2/+2
While testing the virtio-net driver on KVM with TSO I noticed that TSO performance with a 1500 MTU is significantly worse compared to the performance of non-TSO with a 16436 MTU. The packet dump shows that most of the packets sent are smaller than a page. Looking at the code this actually is quite obvious as it always stop extending the packet if it's the first packet yet to be sent and if it's larger than the MSS. Since each extension is bound by the page size, this means that (given a 1500 MTU) we're very unlikely to construct packets greater than a page, provided that the receiver and the path is fast enough so that packets can always be sent immediately. The fix is also quite obvious. The push calls inside the loop is just an optimisation so that we don't end up doing all the sending at the end of the loop. Therefore there is no specific reason why it has to do so at MSS boundaries. For TSO, the most natural extension of this optimisation is to do the pushing once the skb exceeds the TSO size goal. This is what the patch does and testing with KVM shows that the TSO performance with a 1500 MTU easily surpasses that of a 16436 MTU and indeed the packet sizes sent are generally larger than 16436. I don't see any obvious downsides for slower peers or connections, but it would be prudent to test this extensively to ensure that those cases don't regress.

2008-03-21[SPARC64]: Remove most limitations to kernel image size.David S. Miller6-159/+96
Currently kernel images are limited to 8MB in size, and this causes problems especially when enabling features that take up a lot of kernel image space such as lockdep. The code now will align the kernel image size up to 4MB and map that many locked TLB entries. So, the only practical limitation is the number of available locked TLB entries which is 16 on Cheetah and 64 on pre-Cheetah sparc64 cpus. Niagara cpus don't actually have hw locked TLB entry support. Rather, the hypervisor transparently provides support for "locked" TLB entries since it runs with physical addressing and does the initial TLB miss processing. Fully utilizing this change requires some help from SILO, a patch for which will be submitted to the maintainer. Essentially, SILO will only currently map up to 8MB for the kernel image and that needs to be increased. Note that neither this patch nor the SILO bits will help with network booting. The openfirmware code will only map up to a certain amount of kernel image during a network boot and there isn't much we can to about that other than to implemented a layered network booting facility. Solaris has this, and calls it "wanboot" and we may implement something similar at some point. Signed-off-by: David S. Miller <davem@davemloft.net>
