* | net: remove driver_data direct access of struct device from more driversGreg Kroah-Hartman2009-05-041-4/+4
|/ | | | | | | | | | | In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

* net/ehea: use consistant typeStephen Rothwell2009-01-061-8/+8
| | | | | | | | | | | | ehea_plpar_hcall9() takes an "unsigned long" array to return its results, so change the arrays we pass to it to match. This is currently only 64 bit code, so the transformation is actually a noop, but because ehea_plpar_hcall9() copies the values of registers into the array, if this was ported to a 32 bit hypervisor interface "unsigned long" would probably still be the correct type.

* net/ehea: bitops work on unsigned longsStephen Rothwell2009-01-052-3/+2
| | | | | | | | | | | | | | | The flags field of struct ehea_port is only used with test_bit(), clear_bit() and set_bit() and these interfaces only work on "unsigned long"s, so change the field to be an "unsigned long". Also, this field only has two bits defined for it (0 and 1) so will still be fine if someone builds this driver for a 32 bit arch (at least as far as this flags field is concerned). Also note that ehea_driver_flags is only used in ehca_main.c, so make it static in there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

* ehea: Detect 16GB hugepages for firmware restrictionThomas Klein2008-10-273-6/+56
| | | | | | | | | | | | All kernel memory which is used for kernel/hardware data transfer must be registered with firmware using "memory regions". 16GB hugepages may not be part of a memory region due to firmware restrictions. This patch modifies the walk_memory_resource callback fn to filter hugepages and add only standard memory to the busmap which is later on used for MR registration.

* net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller2008-06-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

* ehea: add kdump supportThomas Klein2008-02-232-25/+290
| | | | | | | | | | | | This patch adds kdump support to the ehea driver. As the firmware doesn't free resource handles automatically, the driver has to run an as simple as possible free resource function in case of a crash shutdown. The function iterates over two arrays freeing all resource handles which are stored there. The arrays are kept up-to-date during normal runtime. The crash handler fn is triggered by the recently introduced PPC crash shutdown reg/unreg functions. Signed-off-by: Thomas Klein <tklein@de.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | Due to changes in the struct device_driver there is no direct access to its kobj any longer. The kobj was used to create sysfs links between eHEA ethernet devices and the driver. This patch removes the affected sysfs links to resolve the build problems.
