2018-05-10powerpc: wii_defconfig: Disable Ethernet driver support codeJonathan Neuschäfer1-0/+1
The Wii doesn't have built-in Ethernet and USB Ethernet adapters are in a different menu. Disable CONFIG_ETHERNET to save some space in support code for Ethernet drivers. Note that this patch doesn't disable any Ethernet drivers, because they are not enabled by default.

2018-05-10powerpc/pseries: hcall_exit tracepoint retval should be signedMichael Ellerman4-9/+6
The hcall_exit() tracepoint has retval defined as unsigned long. That leads to humours results like: bash-3686 [009] d..2 854.134094: hcall_entry: opcode=24 bash-3686 [009] d..2 854.134095: hcall_exit: opcode=24 retval=18446744073709551609 It's normal for some hcalls to return negative values, displaying them as unsigned isn't very helpful. So change it to signed. bash-3711 [001] d..2 471.691008: hcall_entry: opcode=24 bash-3711 [001] d..2 471.691008: hcall_exit: opcode=24 retval=-7 Which can be more easily compared to H_NOT_FOUND in hvcall.h Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Anton Blanchard <anton@samba.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Tested-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com>
2018-05-10arm64: dts: juno/rtsm: re-structure motherboard includesSudeep Holla4-226/+232
It is a bit unorthodox to just include a file in the middle of a another DTS file, it breaks the pattern from other device trees and also makes it really hard to reference things across the files with phandles. Restructure the include for the Juno/RTSM motherboards to happen at the top of the file, reference the target nodes directly, and indent the motherboard .dtsi files to reflect their actual depth in the hierarchy. This is a purely syntactic change that result in the same DTB files from the DTS/DTSI files. This is based on similar patch from Linus Walleij for ARM Vexpress platforms.

The 7278 device is the first device that includes support for the V7 memory map developed for use in 64-bit architecture brcmstb devices. This map relocates the register physical offset from 0xF0000000 to 0x0000000008000000. Since the ARM PERIPHBASE value is also relocated in the V7 memory map we can use its value to determine whether this device uses the new V7 memory map and therefore where to look for the SUN_TOP_CTRL register used to identify the chip family.

2018-05-09s390/early: get rid of memmove_earlyHeiko Carstens1-33/+1
memmove_early was introduced with commit d543a106f96d6 ("s390: fix initrd corruptions with gcov/kcov instrumented kernels"). The reason for writing this extra memmove implementation was to be able to move memory from an unknown location (aka SCSI IPL parameter block) to a known location. This had to done early before it was known if the SCSI IPL parameter block pointer was valid or not, and therefore the memmove implementation was supposed to be able to handle program checks. The code has been changed and especially with commit d08091ac9654 ("s390/ipl: rely on diag308 store to get ipl info") and commit b4623d4e5b23 ("s390: provide memmove implementation") there is no need to have a memmove version that can handle program checks, and in addition it cannot be gcov/kcov instrumented anymore.

This way we have one central definition of it, and user can select it as needed. The new option is not user visible, which is the behavior it had in most architectures, with a few notable exceptions: - On x86_64 and mips/loongson3 it used to be user selectable, but defaulted to y. It now is unconditional, which seems like the right thing for 64-bit architectures without guaranteed availablity of IOMMUs. - on powerpc the symbol is user selectable and defaults to n, but many boards select it.
