2008-04-16[netdrvr] tulip: Better MWI workaround for 21143 rev 65 chip errataPeter Horton2-15/+11
This patch works around the MWI bug on the DC21143 rev 65 Tulip by ensuring that the receive buffers don't end on a cache line boundary (as documented in the errata). This patch is required for the MIPS based Cobalt Qube/RaQ as supporting the extra PCI commands seems to reduce the chance of a hard lockup between the Tulip and the PCI bridge.

2008-04-16[netdrvr] tulip/winbond-840: don't let tulip.h symbol stomp oursJeff Garzik1-2/+3
winbond-840 shares tulip.h with the tulip driver, because they share many (but not all) of the same register definitions. This is useful for the register definitions, but not helpful when it comes to symbols that are shared among the tulip driver's C modules, but not meant to be shared outside that one driver. Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding upon a similar symbol in winbond-840's namespace. This was not a problem as long as the two symbols had the same value, but upcoming patches result in differing symbol values. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val).

2008-04-16spidernet: fix error interrupt handlingIshizaki Kou1-12/+10
In addition to the value of GHIINT0STS, spidernet interrupt handler should check the values of GHIINT1STS/GHIINT2STS registers at the beginning of spider_net_interrupt() so as not to drop error interrupts. GHIINT1STS/GHIINT2STS registers indicates some of erroneous conditions in spidernet, and a few bits of GHIINT0STS register reflects these conditions. But GHIINT0MSK masks these bits, so you should check these conditions by reading GHIINT1STS/GHIINT2STS registers directly.

2008-04-16[TUN]: Allow to register tun devices in namespace.Pavel Emelyanov1-0/+4
This is basically means that a net is set for a new device, but actually also involves two more steps: 1. mark the tun device as "local", i.e. do not allow for it to move across namespaces. This is done so, since tun device is most often associated to some file (and thus to some process) and moving the device alone is not valid while keeping the file and the process outside. The need in ability to move a detached persistent device is to be investigated later. 2. get the tun device's net when tun becomes attached and put one when it becomes detached. This is needed to handle the case when a task owning the tun dies, but a files lives for some more time - in this case we must not allow for net to be freed, since its exit hook will spoil that file's private data by unregistering the tun from under tun_chr_close.

2008-04-12tg3: fix MMIO for PPC 44x platformsSergei Shtylyov1-3/+4
The driver stores the PCI resource addresses into 'unsigned long' variable before calling ioremap_nocache() on them. This warrants kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion that the PCI memory resource is mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

2008-04-12forcedeth: mac address fixAyaz Abdulla1-2/+24
This critical patch fixes a mac address issue recently introduced. If the device's mac address was in correct order and the flag NVREG_TRANSMITPOLL_MAC_ADDR_REV was set, during nv_remove the flag would get cleared. During next load, the mac address would get reversed because the flag is missing. As it has been indicated previously, the flag is cleared across a low power transition. Therefore, the driver should set the mac address back into the reversed order when clearing the flag. Also, the driver should set back the flag after a low power transition to protect against kexec command calling nv_probe a second time.

So don't use print_mac() in such cases in hot code paths, use MAC_FMT et al. instead. As noted by Joe Perches, pr_debug() could be modified to handle this better, but that is a change to an interface used by the entire kernel and thus needs to be validated carefully.
