* hv: fix return type of hv_post_message()Dan Carpenter2012-04-091-1/+1
| | | | | | | | | | This function returns negative error codes, but because the type is u16 they get truncated into positive numbers. It doesn't look like the callers care, but we should fix it anyway as a cleanup. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: K. Y.

* drivers: hv: Increase the number of VCPUs supported in the guestK. Y. Srinivasan2012-02-091-2/+2
| | | | | | | | | | | | | | The current code arbirarily limited the number of CPUs the guest could have. Change that so that we can support the maximum number of CPUs the guest can support. While we use NR_CPUS to size the per-cpu state all we are allocating based on NR_CPUS are the pointers to per-cpu state that will be allocatted in the context of the initializing CPU. This patch triggers a checkpatch warning for the usage of NR_CPU and since all we are allocating a couple of pointers per CPU, it should be ok. Signed-off-by: K. Y.

* Staging: hv: remove unneeded asm include file in hyperv.hGreg Kroah-Hartman2011-10-111-1/+1
| | | | | | | | No one outside of the hyperv core needs to include the asm/hyperv.h file, so don't put it in the "global" include/linux/hyperv.h file. Cc: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Staging: hv: move hyperv code out of staging directoryGreg Kroah-Hartman2011-10-101-0/+429
After many years wandering the desert, it is finally time for the Microsoft HyperV code to move out of the staging directory. Or at least the core hyperv bus code, and the utility driver, the rest still have some review to get through by the various subsystem maintainers.
