2007-12-11[VLAN]: Fix potential race in vlan_cleanup_module vs vlan_ioctl_handler.Pavel Emelyanov
The vlan module cleanup function starts with vlan_netlink_fini(); vlan_ioctl_set(NULL); The first call removes all the vlan devices and the second one closes the vlan ioctl. AFAIS there's a tiny race window between these two calls - after rtnl unregistered all the vlans, but the ioctl handler isn't set to NULL yet, user can manage to call this ioctl and create one vlan device, and that this function will later BUG_ON seeing non-emply hashes. I think, that we must first close the vlan ioctl and only after this remove all the vlans with the vlan_netlink_fini() call.

2007-12-11[BNX2]: Fix RX packet rot.Michael Chan
Packets can be left in the RX ring if the NAPI budget is reached. This is caused by storing the latest rx index at the beginning of bnx2_rx_int(). We may not process all the work up to this index if the budget is reached and so some packets in the RX ring may rot when we later check for more work using this stored rx index. The fix is to not store this latest hw index and only store the processed rx index. We use a new function bnx2_get_hw_rx_cons() to fetch the latest hw rx index.

2007-12-11[S390]: Fix use of skb after netif_rxJulia Lawall
Recently, Wang Chen submitted a patch (d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb) after a subsequent reference to skb, because netif_rx may call kfree_skb on its argument. netif_rx_ni calls netif_rx, so the same problem occurs in the files below. I have left the updating of dev->last_rx after the calls to netif_rx_ni because it seems time dependent, but moved the other field updates before. This was found using the following semantic match.

2007-12-11[POWERPC] Early debug forces console log level to maxBenjamin Herrenschmidt
This makes the early debug option force the console loglevel to the max. The early debug option is meant to catch messages very early in the kernel boot process, in many cases, before the kernel has a chance to parse the "debug" command line argument. Thus it makes sense when CONFIG_PPC_EARLY_DEBUG is set, to force the console log level to the max at boot time.

2007-12-11[POWERPC] Change 32-bit PCI message about resource allocationBenjamin Herrenschmidt
The 32 bits PCI code will display a rather scary error message PCI: Cannot allocate resource region N of device XXX at boot when the existing setup of a device as left by the firmware doesn't match the kernel needs and the device needs to be moved. This is often not an error at all, as the kernel will generally easily reallocate the device elsewhere. This changes the message to something less scary and lowers its level from error to warning.

2007-12-11[POWERPC] Fix powerpc 32-bit resource fixup for 64-bit resourcesBenjamin Herrenschmidt
The 32-bit powerpc resource fixup code uses unsigned longs to do the offsetting of resources which overflows on platforms such as 4xx where resources can be 64 bits. This fixes it by using resource_size_t instead. However, the IO stuff does rely on some 32 bits arithmetic, so we hack by cropping the result of the fixups for IO resources with a 32 bits mask. This isn't the prettiest but should work for now until we change the 32 bits PCI code to do IO mappings like 64 bits does, within a reserved are of the kernel address space.

This merges the 32-bit and 64-bit implementations of pci_process_bridge_OF_ranges(). The new function is cleaner than both the old ones, and supports 64 bits ranges on ppc32 which is necessary for the 4xx port. It also adds some better (hopefully) output to the kernel log which should help diagnose problems and makes better use of existing OF parsing helpers (avoiding a few bugs of both implementations along the way). There are still a few unfortunate ifdef's but there is no way around these for now at least not until some other bits of the PCI code are made common.

2007-12-10proc: remove/Fix proc generic d_revalidateEric W. Biederman
Ultimately to implement /proc perfectly we need an implementation of d_revalidate because files and directories can be removed behind the back of the VFS, and d_revalidate is the only way we can let the VFS know that this has happened. Unfortunately the linux VFS can not cope with anything in the path to a mount point going away. So a proper d_revalidate method that calls d_drop also needs to call have_submounts which is moderately expensive, so you really don't want a d_revalidate method that unconditionally calls it, but instead only calls it when the backing object has really gone away. proc generic entries only disappear on module_unload (when not counting the fledgling network namespace) so it is quite rare that we actually encounter that case and has not actually caused us real world trouble yet. So until we get a proper test for keeping dentries in the dcache fix the current d_revalidate method by completely removing it. This returns us to the current status quo. So with CONFIG_NETNS=n things should look as they have always looked. For CONFIG_NETNS=y things work most of the time but there are a few rare corner cases that don't behave properly. As the network namespace is barely present in 2.6.24 this should not be a problem. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Cc: "Rafael J.

2007-12-10atmel_spi: reload RCR before TCRRini van Zetten
We have a wifi module connected to the spi bus and got sometimes FIFO overrun errors on the spi bus. After some investigation i found that the driver loads the TCR (transmit count) register before the RCR (receive count). When the transfer list is not empty the atmel_spi_next_message is called while tx and rx are enabled. As soon as the TCR is loaded, hardware starts transfer and causes a rx fifo overrun because the RCR is not loaded yet. Load the RCR before the TCR. After this patch the fifo overrun disapears at out setup.

2007-12-10esp_scsi: fix reset cleanup spinlock recursionMaciej W. Rozycki
The esp_reset_cleanup() function is called with the host lock held and invokes starget_for_each_device() which wants to take it too. Here is a fix along the lines of shost_for_each_device()/__shost_for_each_device() adding a __starget_for_each_device() counterpart which assumes the lock has already been taken. Eventually, I think the driver should get modified so that more work is done as a softirq rather than in the interrupt context, but for now it fixes a bug that causes the spinlock debugger to fire. While at it, it fixes a small number of cosmetic problems with starget_for_each_device() too. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Acked-by: David S.

The follow_hugetlb_page() fix I posted (merged as git commit 5b23dbe8173c212d6a326e35347b038705603d39) missed one case. If the pte is present, but not writable and write access is requested by the caller to get_user_pages(), the code will do the wrong thing. Rather than calling hugetlb_fault to make the pte writable, it notes the presence of the pte and continues. This simple one-liner makes sure we also fault on the pte for this case. Please apply.

This adds a bit more detail to the xmon SLB output. When the valid bit is set, this displays the ESID and VSID values, as well as decoding the segment size -- 1T or 256M -- and displaying the LLP bits. This supresses the output for any slb entries that contain only zeros. sample output from power6 (1T segment support): 00 c000000008000000 40004f7ca3000500 1T ESID= c00000 VSID= 4f7ca3 LLP:100 01 d000000008000000 4000eb71b0000400 1T ESID= d00000 VSID= eb71b0 LLP: 0 08 0000000018000000 0000c8499f8ccc80 256M ESID= 1 VSID= c8499f8cc LLP: 0 09 00000000f8000000 0000d2c1a8e46c80 256M ESID= f VSID= d2c1a8e46 LLP: 0 10 0000000048000000 0000ca87eab1dc80 256M ESID= 4 VSID= ca87eab1d LLP: 0 43 cf00000008000000 400011b260000500 1T ESID= cf0000 VSID= 11b260 LLP:100 sample output from power5 (notice the non-valid but non-zero entries) 10 0000000008000000 00004fd0e077ac80 256M ESID= 0 VSID= 4fd0e077a LLP: 0 11 00000000f8000000 00005b085830fc80 256M ESID= f VSID= 5b085830f LLP: 0 12 0000000048000000 000052ce99fe6c80 256M ESID= 4 VSID= 52ce99fe6 LLP: 0 13 0000000018000000 000050904ed95c80 256M ESID= 1 VSID= 50904ed95 LLP: 0 14 cf00000008000000 0000d59aca40f500 256M ESID=cf0000000 VSID= d59aca40f LLP:100 15 c000000078000000 000045cb97751500 256M ESID=c00000007 VSID= 45cb97751 LLP:100 Tested on power5 and power6.

2007-12-11[POWERPC] Use SLB size from the device treeMichael Neuling
Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.
