linux-stable.git/arch, branch v4.19.7 Linux kernel stable tree ARM: dts: rockchip: Remove @0 from the veyron memory node 2018-12-05T18:32:12+00:00 Heiko Stuebner heiko@sntech.de 2018-11-18T19:03:02+00:00 6e74fc22db9cb76efccdcebe015a8c848c17620b commit 672e60b72bbe7aace88721db55b380b6a51fb8f9 upstream. The Coreboot version on veyron ChromeOS devices seems to ignore memory@0 nodes when updating the available memory and instead inserts another memory node without the address. This leads to 4GB systems only ever be using 2GB as the memory@0 node takes precedence. So remove the @0 for veyron devices.

commit 672e60b72bbe7aace88721db55b380b6a51fb8f9 upstream.

memory@0 nodes when updating the available memory and instead
inserts another memory node without the address.

This leads to 4GB systems only ever be using 2GB as the memory@0
node takes precedence. So remove the @0 for veyron devices.

The function_graph_enter() function does the work of calling the function graph hook function and the management of the shadow stack, simplifying the work done in the architecture dependent prepare_ftrace_return(). Have MIPS use the new code, and remove the shadow stack management as well as having to set up the trace structure.
