| * walk system ram rangeKAMEZAWA Hiroyuki2009-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, walk_memory_resource() was introduced to traverse all memory of "System RAM" for detecting memory hotplug/unplug range. For doing so, flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for memory hotplug. But for using other purpose, /proc/kcore, this may includes some firmware area marked as IORESOURCE_BUSY | IORESOUCE_MEM. This patch makes the check strict to find out busy "System RAM". Note: PPC64 keeps their own walk_memory_resouce(), which walk through ppc64's lmb informaton. Because old kclist_add() is called per lmb, this patch makes no difference in behavior, finally. And this patch removes CONFIG_MEMORY_HOTPLUG check from this function. Because pfn_valid() just show "there is memmap or not* and cannot be used for "there is physical memory or not", this function is useful in generic to scan physical memory range.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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>

* drivers/net/ehea/ehea_main.c: Release mutex in error handling codeJulia Lawall2008-07-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* ehea: Access iph->tot_len with correct endiannessRoland Dreier2008-07-041-1/+1
| | | | | | | | | | | iph->tot_len is stored in network byte order, so access it using ntohs(). This doesn't have any real world impact on ehea, since ehea only exists for big-endian platfroms (at the moment at least) but fixing this gets rid of a sparse warning and avoids having a bad example in the tree.

* ehea: fix race conditionJan-Bernd Themann2008-07-042-7/+16
| | | | | | | | | | | When ehea_stop is called the function cancel_work_sync(&port->reset_task) is used to ensure that the reset task is not running anymore. We need an additional flag to ensure that it can not be scheduled after this call again for a certain time.

* ehea: fix might sleep problemJan-Bernd Themann2008-07-042-12/+12
| | | | | | | | | | A mutex has to be replaced by spinlocks as it can be called from a context which does not allow sleeping. The kzalloc flag GFP_KERNEL has to be replaced by GFP_ATOMIC for the same reason. Signed-off-by: Jan-Bernd Themann <themann@de.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
