Pull asm-generic fixes from Arnd Bergmann: "There is one build fix for Arm platforms that ended up impacting most architectures because of the way the drivers/firmware Kconfig file is wired up: The CONFIG_QCOM_SCM dependency have caused a number of randconfig regressions over time, and some still remain in v5.15-rc4. The fix we agreed on in the end is to make this symbol selected by any driver using it, and then building it even for non-Arm platforms with CONFIG_COMPILE_TEST. To make this work on all architectures, the drivers/firmware/Kconfig file needs to be included for all architectures to make the symbol itself visible. In a separate discussion, we found that a sound driver patch that is pending for v5.16 needs the same change to include this Kconfig file, so the easiest solution seems to have my Kconfig rework included in v5.15. Finally, the branch also includes a small unrelated build fix for NOMMU architectures" Link: https://lore.kernel.org/all/20210928153508.101208f8@canb.auug.org.au/ Link: https://lore.kernel.org/all/20210928075216.4193128-1-arnd@kernel.org/ Link: https://lore.kernel.org/all/20211007151010.333516-1-arnd@kernel.org/ * tag 'asm-generic-fixes-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic/io.h: give stub iounmap() on !MMU same prototype as elsewhere qcom_scm: hide Kconfig symbol firmware: include drivers/firmware/Kconfig unconditionally

pci_iounmap'2: Electric Boogaloo: try to make sense of it all

2021-09-20T00:13:35Z

Nathan Chancellor reports that the recent change to pci_iounmap in commit 9caea0007601 ("parisc: Declare pci_iounmap() parisc version only when CONFIG_PCI enabled") causes build errors on arm64. It took me about two hours to convince myself that I think I know what the logic of that mess of #ifdef's in the header file really aim to do, and rewrite it to be easier to follow. Famous last words. Anyway, the code has now been lifted from that grotty header file into lib/pci_iomap.c, and has fairly extensive comments about what the logic is. It also avoids indirecting through another confusing (and badly named) helper function that has other preprocessor config conditionals. Let's see what odd architecture did something else strange in this area to break things. But my arm64 cross build is clean.

parisc: Declare pci_iounmap() parisc version only when CONFIG_PCI enabled

2021-09-19T17:36:09Z

Linus noticed odd declaration rules for pci_iounmap() in iomap.h and pci_iomap.h, where it dependend on either NO_GENERIC_PCI_IOPORT_MAP or GENERIC_IOMAP when CONFIG_PCI was disabled. Testing on parisc seems to indicate that we need pci_iounmap() only when CONFIG_PCI is enabled, so the declaration of pci_iounmap() can be moved cleanly into pci_iomap.h in sync with the declarations of pci_iomap().

Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)

2021-09-13T17:43:04Z

Merge patch series from Nick Desaulniers to update the minimum gcc version to 5.1. This is some of the left-overs from the merge window that I didn't want to deal with yesterday, so it comes in after -rc1 but was sent before. Gcc-4.9 support has been an annoyance for some time, and with -Werror I had the choice of applying a fairly big patch from Kees Cook to remove a fair number of initializer warnings (still leaving some), or this patch series from Nick that just removes the source of the problem. The initializer cleanups might still be worth it regardless, but honestly, I preferred just tackling the problem with gcc-4.9 head-on. We've been more aggressiuve about no longer having to care about compilers that were released a long time ago, and I think it's been a good thing. I added a couple of patches on top to sort out a few left-overs now that we no longer support gcc-4.x. As noted by Arnd, as a result of this minimum compiler version upgrade we can probably change our use of '--std=gnu89' to '--std=gnu11', and finally start using local loop declarations etc. But this series does _not_ yet do that.
