[PATCH v2 0/7] sparc32: build fixes for all{yes,mod}config builds

From: Sam Ravnborg via B4 Relay
Date: Sat Feb 24 2024 - 12:42:45 EST


This is a small set of patches that address build breakage with
allyesconfig / allmodconfig.

This solves some, but not all, build breakage.
The parport fix depends on the previous patch, the rest are independent
fixes.

With v2 there is a extra patch that drops ZONE_DMA support.
It does not fix any build failure, but a nice cleanup.

Changes in v2:
- Added r-b/tested by (thanks to Randy and Maciej)
- Dropped patch for uhci-grlib.c as it is already upstream (Randy)
- Added a few Fixes (Maciej)
- Fixed commit message when dropping GENERIC_ISA_DMA (Maciej)
- Added new patch that drop ZONE_DMA (Maciej)
- Added new patch to fix section mismatch error

In an allmodconfig build I see a lot of:

modpost: "__udelay" [module] has no CRC!

Similar for a handful of other symbols.
Any hint how to get rid of them would be nice.
I have tried to add the prototype to asm-prototypes.h with no luck.

On top of this the link fails, but I assume this the kernel that grows
too big which is no surprise.
