Drivers:hv: Fix a bug in vmbus_driver_unregister()

2012-01-05T00:14:44+00:00

The function vmbus_exists() was introduced recently to deal with cases where
the vmbus driver failed to initialize and yet other Hyper-V drivers attempted
to register with the vmbus bus driver. This patch introduced a bug where
vmbus_driver_unregister() would fail to unregister the driver. This patch
fixes the problem.

In preparation for eventually supporting kexec in Linux VMs on Hyper-V,
get rid of an unnecessary check in hv_init().

Drivers: hv: Make the vmbus driver unloadable

2011-12-12T22:26:50+00:00

It turns out that the vmbus driver can be made unloadable. Make it
unloadable.

drivers: hv: Don't OOPS when you cannot init vmbus

2011-12-10T00:23:49+00:00

The hv vmbus driver was causing an OOPS since it was trying to register drivers
on top of the bus even if initialization of the bus has failed for some
reason (such as the odd chance someone would run a hv enabled kernel in a
non-hv environment).

hv: Add Kconfig menu entry

2011-11-27T01:05:34+00:00

Most of the drivers/*/Kconfig files define a menu entry. Define
a menu item for hv too such that it becomes uniform with e.g.
virtio for at least "make xconfig" and "make menuconfig" users.

Staging: hv: vmbus: Support building the vmbus driver as part of the kernel

2011-11-27T01:05:34+00:00

Modify the way we initialize the vmbus driver so that all the hyper-v drivers
can be linked with the kernel and still ensure that the vmbus driver
is fully initialized before the drivers that depend upon the vmbus
driver attempt to initialize.

NLS: improve UTF8 -> UTF16 string conversion routine

2011-11-18T18:51:01+00:00

The utf8s_to_utf16s conversion routine needs to be improved.  Unlike
its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
the maximum length of the output buffer or the endianness of its
16-bit output.

This patch (as1501) adds the two missing arguments, and adjusts the
only two places in the kernel where the function is called.  A
follow-on patch will add a third caller that does utilize the new
capabilities.

The two conversion routines are still annoyingly inconsistent in the
way they handle invalid byte combinations.  But that's a subject for a
different patch.

hv: remove struct hv_device_info from hyperv.h

2011-10-11T15:51:22+00:00

This is only used/needed by the vmbus core code, so move it out of the
hyperv.h file and into the .c file that uses it.
