When USBPacket in OUT direction has larger payload
than the ep_out_buffer (of size 512), a buffer overflow
would occur.
It could be fixed by limiting the size of usb_packet_copy
to be at most buffer size. Further optimization gets rid
of the ep_out_buffer and directly uses ep_out as the target

Pointer authentication on aarch64 is pretty expensive (up to 50% of
execution time) when running a virtual machine with tcg and -cpu max

The advice is always: use pauth-impdef=on.

The current code is actually dependent on having just one error
structure with a single source.
As the number of sources should be arch-dependent, as it will depend on
what kind of synchronous/assynchronous notifications will exist, change
the logic to dynamically build the table.

There are two pointers that are needed during error injection:
1. The start address of the CPER block to be stored;
2. The address of the ack, which needs a reset before next error.
It is preferable to calculate them from the HEST table. This allows
checking the source ID, the size of the table
The GHES migration logic at GED should now support HEST table

Hello, Peter.
I beg a pardon, but I guess, we have a misunderstanding here.
The problem is that comparison "if (limit < 0)" will never
be true. Thus, "true" branch is unreachable. According to
the comment below, it was assumed that "limit" may be
negative, and this means, that "QEMU is running to
