sh: platform_early: remove pdev->driver_override check

2026-04-02T11:25:13+00:00

[ Upstream commit c5f60e3f07b6609562d21efda878e83ce8860728 ] In commit 507fd01d5333 ("drivers: move the early platform device support to arch/sh") platform_match() was copied over to the sh platform_early code, accidentally including the driver_override check. This check does not make sense for platform_early, as sysfs is not even available in first place at this point in the boot process, hence remove the check.

kbuild: Split .modinfo out from ELF_DETAILS

2026-03-12T11:09:39+00:00

commit 8678591b47469fe16357234efef9b260317b8be4 upstream. Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and ELF_DETAILS was present in all architecture specific vmlinux linker scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and COMMON_DISCARDS may be used by other linker scripts, such as the s390 and x86 compressed boot images, which may not expect to have a .modinfo section. In certain circumstances, this could result in a bootloader failing to load the compressed kernel [1]. Commit ddc6cbef3ef1 ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with SecureBoot trailer") recently addressed this for the s390 bzImage but the same bug remains for arm, parisc, and x86. The presence of .modinfo in the x86 bzImage was the root cause of the issue worked around with commit d50f21091358 ("kbuild: align modinfo section for Secureboot Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition. Split .modinfo out from ELF_DETAILS into its own macro and handle it in all vmlinux linker scripts. Discard .modinfo in the places where it was previously being discarded from being in COMMON_DISCARDS, as it has never been necessary in those uses.

crypto: ansi_cprng - Remove unused ansi_cprng algorithm

2025-11-22T02:04:50+00:00

Remove ansi_cprng, since it's obsolete and unused, as confirmed at https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/ This was originally added in 2008, apparently as a FIPS approved random number generator. Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around. Suggested-by: Herbert Xu Cc: Haotian Zhang Cc: Neil Horman Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu
