2021-12-17ARM: reduce the information printed in call tracesRussell King
A while back, Linus complained about the numeric values printed by the ARM backtracing code. Printing these values does not make sense if one does not have access to the kernel ELF image (as is normally the case when helping a third party on a mailing list), but if one does, they can be very useful to find the code, rather than searching for the function name, and then doing hex math to work out where the backtrace entry is referring to.

2021-12-17ARM: 9159/1: decompressor: Avoid UNPREDICTABLE NOP encodingAndre Przywara
In the decompressor's head.S we need to start with an instruction that is some kind of NOP, but also mimics as the PE/COFF header, when the kernel is linked as an UEFI application. The clever solution here is "tstne r0, #0x4d000", which in the worst case just clobbers the condition flags, and bears the magic "MZ" signature in the lowest 16 bits. However the encoding used (0x13105a4d) is actually not valid, since bits [15:12] are supposed to be 0 (written as "(0)" in the ARM ARM). Violating this is UNPREDICTABLE, and *can* trigger an UNDEFINED exception. Common Cortex cores seem to ignore those bits, but QEMU chooses to trap, so the code goes fishing because of a missing exception handler at this point. We are just saved by the fact that commonly (with -kernel or when running from U-Boot) the "Z" bit is set, so the instruction is never executed. See [0] for more details. To make things more robust and avoid UNPREDICTABLE behaviour in the kernel code, lets replace this with a "two-instruction NOP": The first instruction is an exclusive OR, the effect of which the second instruction reverts. This does not leave any trace, neither in a register nor in the condition flags. Also it's a perfectly valid encoding. Kudos to Peter Maydell for coming up with this gem.

2021-12-17gpiolib: allow line names from device props to override driver namesPeter Rosin
Some GPIO providers set names for GPIO lines that match the names of the pins on the SoC, or variations on that theme. These names are generic more often that not, such as pioC12 in the at91 case. These generic names block the possibility to set more useful GPIO line names with device properties (i.e. gpio-line-names). Allow overriding a generic name given by the GPIO driver if there is a name given to the GPIO line using device properties, but leave the generic name alone if no better name is available. However, there is a risk. If user space is depending on the above mentioned fixed GPIO names, AND there are device properties that previously did not reach the surface, the name change might cause regressions. But hopefully this stays below the radar...
