openwrt/target/linux/generic/pending-4.19/220-optimize_inlining.patch
Koen Vandeputte cf65262492 kernel: bump 4.19 to 4.19.51 
Refreshed all patches.

Altered patches:
- 370-netfilter-nf_flow_table-fix-offloaded-connection-tim.patch
- 220-optimize_inlining.patch
- 640-netfilter-nf_flow_table-add-hardware-offload-support.patch

This patch also restores the initial implementation
of the ath79 perfcount IRQ issue. (78ee6b1a40)
It was wrongfully backported upstream initially and got reverted now.

Compile-tested on: cns3xxx, imx6
Runtime-tested on: cns3xxx, imx6
