2021-12-21ARM: dts: aspeed: tyan-s7106: Add uart_routing and fix vuart configOskar Senft1-0/+16
Configure the vuart in such a way that it does not inhibit the SuperIO's UART from functioning correctly. This allows the same DTS to be used for both configurations with SuperIO and VUART (depending on the BIOS build). The decision on whether to actually enable VUART can then be made at runtime. This change also enables the new uart_routing driver for the SuperIO case.

The current 'rx-internal-delay-ps' property value on the Realtek switch node, 2000, will be divided by 300, resulting in 6.66, which will be rounded to the closest step value, 7. Change it to 2100 to be accurate. See ef136837aaf6 ("net: dsa: rtl8365mb: set RGMII RX delay in steps of 0.3 ns") for reference. Flow control needs to be enabled on both sides of the internal and external switch. It is already enabled on the CPU port of the Realtek switch so we also enable it on the external switch port of the Broadcom switch as well.

__secondary_data used to reside in r7 around call to PROCINFO_INITFUNC. After commit 95731b8ee63e ("ARM: 9059/1: cache-v7: get rid of mini-stack") r7 is used as a scratch register, so we have to reload __secondary_data before we setup the stack pointer.

2021-12-17ARM: reduce the information printed in call tracesRussell King2-3/+16
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. Provide an option to control whether this information is included, which will only be visible if EXPERT is enabled. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2021-12-17ARM: 9166/1: Support KFENCE for ARMWang Kefeng3-2/+61
Add architecture specific implementation details for KFENCE and enable KFENCE on ARM. In particular, this implements the required interface in <asm/kfence.h>. KFENCE requires that attributes for pages from its memory pool can individually be set. Therefore, force the kfence pool to be mapped at page granularity.

2021-12-17ARM: 9159/1: decompressor: Avoid UNPREDICTABLE NOP encodingAndre Przywara2-9/+16
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.

The properties have been commented out to prevent a regression a while ago. The first regression should be resolved by commit 44af7927316e ("spi: Map SPI OF client IRQ at probe time"). The second regression is probably addressed by commit 494fd7b7ad10 ("PM / core: fix deferred probe breaking suspend resume order") and/or maybe others.
