2020-11-10arm64: dts: marvell: espressobin: Add ethernet switch aliasesPali Rohár
commit b64d814257b027e29a474bcd660f6372490138c7 upstream. Espressobin boards have 3 ethernet ports and some of them got assigned more then one MAC address. MAC addresses are stored in U-Boot environment. Since commit a2c7023f7075c ("net: dsa: read mac address from DT for slave device") kernel can use MAC addresses from DT for particular DSA port. Currently Espressobin DTS file contains alias just for ethernet0. This patch defines additional ethernet aliases in Espressobin DTS files, so bootloader can fill correct MAC address for DSA switch ports if more MAC addresses were specified. DT alias ethernet1 is used for wan port, DT aliases ethernet2 and ethernet3 are used for lan ports for both Espressobin revisions (V5 and V7).

2020-11-10arm64: Change .weak to SYM_FUNC_START_WEAK_PI for arch/arm64/lib/mem*.SFangrui Song
commit ec9d78070de986ecf581ea204fd322af4d2477ec upstream. Commit 39d114ddc682 ("arm64: add KASAN support") added .weak directives to arch/arm64/lib/mem*.S instead of changing the existing SYM_FUNC_START_PI macros. This can lead to the assembly snippet `.weak memcpy ... .globl memcpy` which will produce a STB_WEAK memcpy with GNU as but STB_GLOBAL memcpy with LLVM's integrated assembler before LLVM 12. LLVM 12 (since https://reviews.llvm.org/D90108) will error on such an overridden symbol binding. Use the appropriate SYM_FUNC_START_WEAK_PI instead.

commit 3ac0f4526dfb80625f5c2365bccd85be68db93ef upstream. In an effort to clarify and simplify the annotation of assembly functions in the kernel new macros have been introduced.

2020-11-10arm64: asm: Add new-style position independent function annotationsMark Brown
commit 35e61c77ef386555f3df1bc2057098c6997ca10b upstream. As part of an effort to make the annotations in assembly code clearer and more consistent new macros have been introduced, including replacements for ENTRY() and ENDPROC(). On arm64 we have ENDPIPROC(), a custom version of ENDPROC() which is used for code that will need to run in position independent environments like EFI, it creates an alias for the function with the prefix __pi_ and then emits the standard ENDPROC. Add new-style macros to replace this which expand to the standard SYM_FUNC_*() and SYM_FUNC_ALIAS_*(), resulting in the same object code. These are added in linkage.h for consistency with where the generic assembler code has its macros.
