2007-06-03network drivers: eliminate unneeded kill_vid codeStephen Hemminger14-183/+6
Many drivers had code that did kill_vid, but they weren't doing vlan filtering. With new API the stub is unneeded unless device sets NETIF_F_HW_VLAN_FILTER. Bad habit: I couldn't resist fixing a couple of nearby style things in acenic, and forcedeth.

2007-06-038139cp: fix VLAN unregistrationStephen Hemminger1-13/+4
The 8139cp driver did VLAN unregistration incorrectly. It disables VLAN completely when the first VID is unregistered. It should instead disable VLAN when the group is unregistered by calling cp_vlan_rx_register with a NULL grp.

2007-06-03VLAN: kill_vid is only useful for VLAN filtering devicesStephen Hemminger1-7/+3
The interface for network device VLAN extension was confusing. The kill_vid function is only really useful for devices that do hardware filtering. Devices that only do VLAN receiption without filtering were being forced to provide the hook, and there were bugs in those devices. Many drivers had kill_vid routine that called vlan_group_set_device, with NULL, but that is done already.

2007-06-03qla3xxx: device doesnt do hardware checksumming.Stephen Hemminger1-1/+1
Reading the code for ql_hw_csum_setup(), it is obvious that this driver is broken for IPV6. The driver sets the NETIF_F_HW_SUM flag, but the code for checksum setup only deals with IPV4.

This code corrects the behavior of the t2_readX/t2_writeX routines, and t2_ioreadNN/t2_iowriteNN routines. The value T2_DENSE_MEM is now subtracted from the "xaddr" argument in each of the readX/writeX routines, since those routines may be called directly, rather than always through the ioreadNN/iowriteNN routines. Examples of the direct calls, via the __raw_readX/writeX macros, are the memcpy_fromio/toio, _memset_c_io, and scr_memcpyw routines.

2007-06-01ALPHA: support graphics on non-zero PCI domainsJay Estabrook12-112/+190
This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.

2007-06-01atmel_spi dma address bugfixHaavard Skinnemoen1-4/+4
When either rx_buf or tx_buf is not being used, i.e. for plain read- or write operations, the atmel_spi uses a fixed-size DMA buffer instead. If the transfer is longer than the size of this buffer, it is split into multiple DMA transfers. When the transfer is split like this, the atmel_spi driver ends up using the same DMA address again and again even for the buffer that came from the user, which is of course wrong. Fix this by adding the number of bytes already transferred to the DMA address so that the data ends up in the right place. Thanks to Wu Xuan for discovering this bug.

2007-06-01potential parse error in ifdefYoann Padioleau9-9/+9
I have made a tool to parse the kernel that does not pre-process the source. That means that my parser tries to parse all the code, including code in the #else branch or code that is not often compiled because the driver is not very used (or not used at all). So, my parser sometimes reports parse error not originally detected by gcc. Here is my (first) patch.

2007-06-01Fix possible UDF data corruptionJan Kara1-4/+8
update_next_aext() could possibly rewrite values in elen and eloc, possibly leading to data corruption when rewriting a file. Use temporary variables instead. Also advance cur_epos as it can also point to an indirect extent pointer.

2007-06-01x86_64: allocate sparsemem memmap above 4GZou Nan hai3-0/+18
On systems with huge amount of physical memory, VFS cache and memory memmap may eat all available system memory under 4G, then the system may fail to allocate swiotlb bounce buffer. There was a fix for this issue in arch/x86_64/mm/numa.c, but that fix dose not cover sparsemem model. This patch add fix to sparsemem model by first try to allocate memmap above 4G.
