2020-03-25objtool: Optimize find_rela_by_dest_range()Peter Zijlstra2-5/+26
Perf shows there is significant time in find_rela_by_dest(); this is because we have to iterate the address space per byte, looking for relocation entries.

2020-03-25objtool: Optimize find_symbol_by_index()Peter Zijlstra2-10/+6
The symbol index is object wide, not per section, so it makes no sense to have the symbol_hash be part of the section object. By moving it to the elf object we avoid the linear sections iteration. This reduces the runtime of objtool on vmlinux.o from over 3 hours (I gave up) to a few minutes. The defconfig vmlinux.o has around 20k sections.

2020-03-25libata: Assign OF node to the SCSI deviceLinus Walleij1-0/+30
When we spawn a SCSI device from an ATA device in libata-scsi the SCSI device had no relation to the device tree. The DT binding allows us to define port nodes under a PATA (IDE) or SATA host controller, so we can have proper device nodes for these devices. If OF is enabled, walk the children of the host controller node to see if there is a valid device tree node to assign. The reg is used to match to ID 0 for the master device and ID 1 for the slave device. The corresponding device tree bindings have been accepted by the device tree maintainers.
