https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-rolling-stable2022-09-28T09:22:10Zpowerpc: add ISA v3.0 / v3.1 wait opcode macro2022-09-28T09:22:10ZNicholas Piggin2022-09-20T12:22:58Zurn:sha1:dabeb572adf24bbd7cb21d1cc4d118bdf2c2ab74
The wait instruction encoding changed between ISA v2.07 and ISA v3.0.
In v3.1 the instruction gained a new field.
Update the PPC_WAIT macro to the current encoding. Rename the older
incompatible one with a _v203 suffix as it was introduced in v2.03
(the WC field was introduced in v2.07 but the kernel only uses WC=0).

powerpc: Cleanup idle for e5002022-09-26T13:00:14ZChristophe Leroy2022-09-19T17:01:42Zurn:sha1:6556fd1a1e9fcd180348c4368d2387bdc6a17613
e500 idle setup is a bit messy.
e500_idle() is used for PPC32 while book3e_idle() is used for PPC64.
As they are mutually exclusive, call them all e500_idle().
Use CONFIG_MPC_85xx instead of PPC32 + E500 in Makefile and rename
idle_e500.c to idle_85xx.c .
Rename idle_book3e.c to idle_64e.c and remove #ifdef PPC64 in
as it's only built on PPC64.
