commit e7020bb068d8be50a92f48e36b236a1a1ef9282e upstream.
Analogically to what we did in 2800aadc18a6 ("iwlwifi: Fix softirq/hardirq disabling in iwl_pcie_enqueue_hcmd()"), we must apply the same fix to iwl_pcie_gen2_enqueue_hcmd(), as it's being called from exactly the same contexts.
Greg, This patch and above mentioned earlier patch "iwlwifi: Fix softirq/hardirq disabling in iwl_pcie_enqueue_hcmd()", upstream commit 2800aadc18a64c96b051bcb7da8a7df7d505db3f, both need to be backported to older kernels too.
I see that there are trivial context rejects if/when you attempt to apply those patches to older kernels. Those trivial context rejects should not prevent backporting them. Maybe run both patches through sed?
sed -e s/iwl_txq_space/iwl_queue_space/ -e s/iwl_txq_get_/iwl_pcie_get_/
My ability test in-tree iwlwifi is limited. I compile out-of-tree iwlwifi source, and testing that is limited to pinging mobile-wifi router that does not have SIM-card.
