The driver stores the PCI resource address into 'unsigned long' variable before
calling ioremap() on it. This warrants a 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 of the
PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of
this trick, having instead CONFIG_RESOURCES_64BIT enabled.

When detaching the last QP from an MCG entry, we need to make

QPs which is linked to the list of the MCGs of the corresponding

The struct mlx4_interface.event() method was supposed to get an enum
mlx4_dev_event, but the driver code was actually passing in the
hardware enum mlx4_event values. Fix up the callers of
mlx4_dispatch_event() so that they pass in the right type of value,
and fix up the event method in mlx4_ib so that it can handle the enum
mlx4_dev_event values.
This eliminates the need for the subtype parameter to the event
method, so remove it.
This also fixes the sparse warning

drivers/net/sb1000.c has lots of inlined static functions.
Mst of them are used at initialization, wait for some
hardware register to change (wait using yield, sleep etc),
or do slow port-based I/O. Inlining thse "for speed" makes no sense.
This patch removes "inline" from biggest static function
(regardless of number of callsites - gcc nowadays auto-inlines
statics with one callsite).

ensuring that the receive buffers don't end on a cache line boundary

supporting the extra PCI commands seems to reduce the chance of a hard

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.

In addition to the value of GHIINT0STS, spidernet interrupt handler
should check the values of GHIINT1STS/GHIINT2STS registers at the

GHIINT1STS/GHIINT2STS registers indicates some of erroneous conditions
