treewide: refresh kmalloc_obj() conversionsgrafted
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

+ APEI allows to report errors (for example from the chipset)
+ to the operating system. This improves NMI handling
+ especially. In addition it supports error serialization and

+ Generic Hardware Error Source provides a way to report
+ platform hardware errors (such as that from chipset). It
+ works in so called "Firmware First" mode, that is, hardware
+ errors are reported to firmware firstly, then reported to
+ Linux by firmware. This way, some non-standard hardware
+ error registers or non-standard hardware link can be checked
+ by firmware to produce more valuable hardware error
+ information for Linux.

+ and firmware implementation.
