Use kmem_cache_zalloc instead of manually setting kmem_cache_alloc with flag GFP_ZERO since kmem_alloc_zalloc sets allocated memory to zero. The Coccinelle semantic patch used to make this change is as follows: // <smpl> @@ expression e,f; @@ - kmem_cache_alloc(e, f |__GFP_ZERO) + kmem_cache_zalloc(e, f) // </smpl> Signed-off-by:

As it is ENABLE_PINGER is never defined, but in reality it's the code that is now compiled out that should be used since all other instances were converted like that too. Signed-off-by:

These two comments certainly refer to some ifdefed code that is no longer present, so remove them too. Signed-off-by:

This patch saves off the create_bus and create_device controlvm messages for the visorhba device, so that they can be resurrected and used in the kdump kernel. After this patch, a crash dump can be generated using: # service kdump start # echo 1 > /proc/sys/kernel/sysrq # echo c > /proc/sysrq-trigger Signed-off-by:Timothy Sell <timothy.sell@unisys.com> Signed-off-by:

Use the dynamic size of the controlvm channel (struct channel_header.size) instead of the statically computed sizeof(struct controlvm_channel) when determining the valid bounds for visorchannel_read() and visorchannel_write(). This prevents an observed problem where kdump was failing because controlvm_channel.local_crash_msg_offset was pointing beyond the statically computed size of the channel, even though the channel was physically large enough. This was causing visorchannel_read() to unecessarily fail, because we thought we were attempting to access memory outside of the channel. Signed-off-by:

Tim Sell authored
Previously if controlvm message payloads (indicated in controlvm message via struct controlvm_message.hdr.payload_vm_offset) were contained within the bounds of the channel memory, we would fail to process any controlvm message that contained payload data. Reason is, the request_mem_region() would fail, because it overlapped the channel memory. Since request_mem_region() doesn't actually serve a functional purpose anyway, this was simply removed.

With concurrency managed workqueues, use of dedicated workqueues can be replaced by using system_wq. Drop visornic_timeout_reset_workqueue by using system_wq. Since there is only one work item per devdata and different devdatas do not need to be ordered, increase of concurrency level by switching to system_wq should not break anything. cancel_work_sync() is used to ensure that work is not pending or executing on any CPU.
