treewide: fix typo "previlege"

2025-05-12T00:54:10+00:00

There are some spelling mistakes of 'previlege' in comments which should be 'privilege'. Fix them and add it to scripts/spelling.txt. The typo in arch/loongarch/kvm/main.c was corrected by a different patch [1] and is therefore not included in this submission.

accel/habanalabs: separate nonce from max_size in cpucp_packet struct

2024-06-23T06:53:04+00:00

In struct cpucp_packet both nonce and data_max_size members are in an union overlapping each other. This is a problem as they both are used in attestation and info_signed packets. The solution here is to move the nonce member to a different union under the same structure. Signed-off-by: Dani Liberman Reviewed-by: Ofir Bitton Signed-off-by: Ofir Bitton
