2022-04-08ARM: 9187/1: JIVE: fix return value of __setup handlerRandy Dunlap1-3/+3
commit 8b2360c7157b462c4870d447d1e65d30ef31f9aa upstream. __setup() handlers should return 1 to obsolete_checksetup() in init/main.c to indicate that the boot option has been handled. A return of 0 causes the boot option/value to be listed as an Unknown kernel parameter and added to init's (limited) argument or environment strings. Also, error return codes don't mean anything to obsolete_checksetup() -- only non-zero (usually 1) or zero. So return 1 from jive_mtdset().

2022-04-08ARM: iop32x: offset IRQ numbers by 1Arnd Bergmann4-33/+37
commit 9d67412f24cc3a2c05f35f7c856addb07a2960ce upstream. iop32x is one of the last platforms to use IRQ 0, and this has apparently stopped working in a 2014 cleanup without anyone noticing. This interrupt is used for the DMA engine, so most likely this has not actually worked in the past 7 years, but it's also not essential for using this board. I'm splitting out this change from my GENERIC_IRQ_MULTI_HANDLER conversion so it can be backported if anyone cares.

[ Upstream commit d11967870815b5ab89843980e35aab616c97c463 ] Tweak the ftrace return paths to avoid redundant loads of SP, as well as unnecessary clobbering of IP. This also fixes the inconsistency of using MOV to perform a function return, which is sub-optimal on recent micro-architectures but more importantly, does not perform an interworking return, unlike compiler generated function returns in Thumb2 builds.

[ Upstream commit 515415d316168c6521d74ea8280287e28d7303e6 ] While the HVS has the same context memory size in the BCM2711 than in the previous SoCs, the range allocated to the registers doubled and it now takes 16k + 16k, compared to 8k + 16k before. The KMS driver will use the whole context RAM though, eventually resulting in a pointer dereference error when we access the higher half of the context memory since it hasn't been mapped.
