ehea: Detect 16GB hugepages for firmware restriction

2008-10-27T18:49:55+00:00

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.

ehea: Fix memory hotplug support

2008-10-22T10:22:17+00:00

This patch implements the memory notifier to update the busmap
instantly instead of rebuilding the whole map. This is necessary
because walk_memory_resource provides different information than
required during memory hotplug.

ehea: fix mutex and spinlock use

2008-09-24T22:58:55+00:00

  Looks like to me that the ehea_fw_handles.lock mutex and the
ehea_bcmc_regs.lock spinlock are taken much longer than necessary and could
as well be pushed inside the functions that need them
(ehea_update_firmware_handles() and ehea_update_bcmc_registrations())
rather than at each callsite.

ehea: Fix DLPAR memory handling

2008-09-24T22:49:00+00:00

The ehea busmap must be allocated only once in the first of many calls of the
ehea_create_busmap_callback.

drivers/net/ehea/ehea_main.c: Release mutex in error handling code

2008-07-30T21:23:39+00:00

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/)

// 
@@
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);
)

ehea: Access iph->tot_len with correct endianness

2008-07-04T12:15:28+00:00

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 condition

2008-07-04T12:10:41+00:00

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.
