pasemi_mac: mac_to_intf() error not noticed

2009-04-27T10:20:17+00:00

mac_to_intf() can return -1 when no device or function is found, but when
mac->dma_if is unsigned. The error wasn't noticed.

net: Rework pasemi_mac driver to use of_mdio infrastructure

2009-04-27T09:53:49+00:00

This patch simplifies the driver by making use of more common code.

net: Remove redundant NAPI functions

2009-01-21T22:33:50+00:00

Following the removal of the unused struct net_device * parameter from
the NAPI functions named *netif_rx_* in commit 908a7a1, they are
exactly equivalent to the corresponding *napi_* functions and are
therefore redundant.

powerpc: Change u64/s64 to a long long integer type

2009-01-13T03:47:59+00:00

Convert arch/powerpc/ over to long long based u64:

 -#ifdef __powerpc64__
 -# include 
 -#else
 -# include 
 -#endif
 +#include 

This will avoid reoccuring spurious warnings in core kernel code that
comes when people test on their own hardware. (i.e. x86 in ~98% of the
cases) This is what x86 uses and it generally helps keep 64-bit code
32-bit clean too.

net: Fix unused variable warnings in pasemi_mac.c and spider_net.c

2008-12-29T04:15:38+00:00

As reported by Stephen Rothwell:

--------------------
Today's linux-next build (powerpc ppc64_defconfig) produced these new
warnings:

drivers/net/pasemi_mac.c: In function 'pasemi_mac_rx_intr':
drivers/net/pasemi_mac.c:957: warning: unused variable 'dev'
drivers/net/pasemi_mac.c: In function 'pasemi_mac_poll':
drivers/net/pasemi_mac.c:1637: warning: unused variable 'dev'
drivers/net/spider_net.c: In function 'spider_net_poll':
drivers/net/spider_net.c:1280: warning: unused variable 'netdev'

Probably caused by commit 908a7a16b852ffd618a9127be8d62432182d81b4 ("net:
Remove unused netdev arg from some NAPI interfaces").

net: Remove unused netdev arg from some NAPI interfaces.

2008-12-23T04:43:12+00:00

When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

net: convert print_mac to %pM

2008-10-28T00:06:18+00:00

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

dma-mapping: add the device argument to dma_mapping_error()

2008-07-26T19:00:03+00:00

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
architecture does:

This enables us to cleanly fix the Calgary IOMMU issue that some devices
are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).

I think that per-device dma_mapping_ops support would be also helpful for
KVM people to support PCI passthrough but Andi thinks that this makes it
difficult to support the PCI passthrough (see the above thread).  So I
CC'ed this to KVM camp.  Comments are appreciated.

A pointer to dma_mapping_ops to struct dev_archdata is added.  If the
pointer is non NULL, DMA operations in asm/dma-mapping.h use it.  If it's
NULL, the system-wide dma_ops pointer is used as before.

If it's useful for KVM people, I plan to implement a mechanism to register
a hook called when a new pci (or dma capable) device is created (it works
with hot plugging).  It enables IOMMUs to set up an appropriate
dma_mapping_ops per device.

The major obstacle is that dma_mapping_error doesn't take a pointer to the
device unlike other DMA operations.  So x86 can't have dma_mapping_ops per
device.  Note all the POWER IOMMUs use the same dma_mapping_error function
so this is not a problem for POWER but x86 IOMMUs use different
dma_mapping_error functions.

The first patch adds the device argument to dma_mapping_error.  The patch
is trivial but large since it touches lots of drivers and dma-mapping.h in
all the architecture.

This patch:

dma_mapping_error() doesn't take a pointer to the device unlike other DMA
operations.  So we can't have dma_mapping_ops per device.

Note that POWER already has dma_mapping_ops per device but all the POWER
IOMMUs use the same dma_mapping_error function.  x86 IOMMUs use device
argument.
