For libertas_sdio this is a regression introduced by 23b149c1890f9. The correct fix to the issue described there is simply to remove the assignment.

The code should be compiled in when CONFIG_BCM47XX is selected and not when CONFIG_SSB_DRIVER_MIPS is selected, because nvram_getenv is only available on bcm47xx platforms and now in the mainline kernel code. Using an include is better than a second function declaration, to fix this when the function signature changes. Signed-off-by: Hauke Mehrtens Signed-off-by: David S.

Among them was a per-cpu flag that indicated we were in a path that held locks which could cause the netpoll path to block in during tx, and as such the tx path should queue the frame for later use. This appears to have given rise to a regression. If one of those paths on which we hold the per-cpu flag yields the cpu, its possible for us to come back on a different cpu, leading to us clearing a different flag than we set. This results in odd netpoll drops, and BUG backtraces appearing in the log, as we check to make sure that we only clear set bits, and only set clear bits. I had though briefly about changing the offending paths so that they wouldn't sleep, but looking at my origional work more closely, it doesn't appear that a per-cpu flag is warranted. We alrady gate the checking of this flag on IFF_IN_NETPOLL, so we don't hit this in the normal tx case anyway. And practically speaking, the normal use case for netpoll is to only have one client anyway, so we're not going to erroneously queue netpoll frames when its actually safe to do so. As such, lets just convert that per-cpu flag to an atomic counter. It fixes the rescheduling bugs, is equivalent from a performance perspective and actually eliminates some code in the process.

Removing usage of rtnl_lock() to protect firmware interface registers. These registers are accessed in some worker threads and can create a deadlock if rtnl_lock is taken by upper layers while the worker is still pending. We remove rtnl_lock and use a driver mutex just while mailboxes are accessed. Signed-off-by: Ron Mercer Signed-off-by: David S.
