SPDM is used for debug/profiling and does not have any other functionality. These clocks can safely be removed.

[ Upstream commit bab537805a10bdbf55b31324ba4a9599e0651e5e ]
NO_IRQ is a relic from the old days. It is not used anymore in core functions. By the way, function irq_of_parse_and_map() returns value 0 on error.
In some drivers, NO_IRQ is erroneously used to check the return of irq_of_parse_and_map().
It is not a real bug today because the only architectures using the drivers being fixed by this patch define NO_IRQ as 0, but there are architectures which define NO_IRQ as -1. If one day those architectures start using the non fixed drivers, there will be a problem.
Long time ago Linus advocated for not using NO_IRQ, see https://lore.kernel.org/all/Pine.LNX.4.64.0511211150040.13959@g5.osdl.org
He re-iterated the same view recently in https://lore.kernel.org/all/CAHk-=wg2Pkb9kbfbstbB91AJA2SF6cySbsgHG-iQMq56j3V...
So test !irq instead of tesing irq == NO_IRQ.
All other usage of NO_IRQ for powerpc were removed in previous cycles so the time has come to remove NO_IRQ completely for powerpc.

In order for KCSAN to increase its likelihood of observing a data race, it sets a watchpoint on memory accesses and stalls, allowing for detection of conflicting accesses by other kernel threads or interrupts.
Stalls are implemented by injecting a call to udelay in instrumented code. To prevent recursive instrumentation, exclude udelay from being instrumented.

[ Upstream commit b6b17a8b3ecd878d98d5472a9023ede9e669ca72 ]
Previously, R_ALPHA_LITERAL relocations would overflow for large kernel modules.
This was because the Alpha's apply_relocate_add was relying on the kernel's module loader to have sorted the GOT towards the very end of the module as it was mapped into memory in order to correctly assign the global pointer. While this behavior would mostly work fine for small kernel modules, this approach would overflow on kernel modules with large GOT's since the global pointer would be very far away from the GOT, and thus, certain entries would be out of range.
This patch fixes this by instead using the Tru64 behavior of assigning the global pointer to be 32KB away from the start of the GOT. The change made in this patch won't work for multi-GOT kernel modules as it makes the assumption the module only has one GOT located at the beginning of .got, although for the vast majority kernel modules, this should be fine. Of the kernel modules that would previously result in a relocation error, none of them, even modules like nouveau, have even come close to filling up a single GOT, and they've all worked fine under this patch.

There is no bug here since no code checks the actual value of these fields, just whether or not they are zero (boolean context), but this can be easily fixed by switching to an unsigned type.

This patch fixes a FLR bug on the SNET DPU rev 1 by setting the PCI_DEV_FLAGS_NO_FLR_RESET flag.
As there is a quirk to avoid FLR (quirk_no_flr), I added a new quirk to check the rev ID before calling to quirk_no_flr.
Without this patch, a SNET DPU rev 1 may hang when FLR is applied.
