speculative execution's side effects left in level 1 cache to infer the
victim's data.
Yet another variant 2 attack vector is for the attacker to poison the
Branch History Buffer (BHB) to speculatively steer an indirect branch
to a specific Branch Target Buffer (BTB) entry, even if the entry isn't
associated with the source address of the indirect branch. Specifically,
the BHB might be shared across privilege levels even in the presence of
Enhanced IBRS.
Currently the only known real-world BHB attack vector is via
unprivileged eBPF. Therefore, it's highly recommended to not enable
unprivileged eBPF, especially when eIBRS is used (without retpolines).
For a full mitigation against BHB attacks, it's recommended to use
retpolines (or eIBRS combined with retpolines).

Garbage collect fbdev scrolling acceleration
--------------------------------------------
Scroll acceleration is disabled in fbcon by hard-wiring p->scrollmode =
SCROLL_REDRAW. There's a ton of code this will allow us to remove:
- lots of code in fbcon.c
- a bunch of the hooks in fbcon_ops, maybe the remaining hooks could be called
directly instead of the function table (with a switch on p->rotate)
- fb_copyarea is unused after this, and can be deleted from all drivers
Note that not all acceleration code can be deleted, since clearing and cursor
support is still accelerated, which might be good candidates for further
deletion projects.

If a filter is placed on a string pointer ``(char *)`` that does not point
to a string on the ring buffer, but instead points to kernel or user space
memory, then, for safety reasons, at most 1024 bytes of the content is
copied onto a temporary buffer to do the compare. If the copy of the memory
faults (the pointer points to memory that should not be accessed), then the

/*
* U-Boot port for Turris Mox has a bug which always expects that "ranges" DT property

* 2 size cells and also expects that the second range starts at 16 MB offset. If these
* 2 size cells and also expects that the second range starts at 16 MB offset. Also it
* expects that first range uses same address for PCI (child) and CPU (parent) cells (so
* no remapping) and that this address is the lowest from all specified ranges. If these
* conditions are not met then U-Boot crashes during loading kernel DTB file. PCIe address
* space is 128 MB long, so the best split between MEM and IO is to use fixed 16 MB window
* for IO and the rest 112 MB (64+32+16) for MEM, despite that maximal IO size is just 64 kB.
