arm64/scs: Fix potential sign extension issue of advance_loc4

2026-05-23T11:03:27+00:00

[ Upstream commit 4023b7424ecd5d38cc75b650d6c1bf630ef8cb40 ] The expression (*opcode++ << 24) and exp * code_alignment_factor may overflow signed int and becomes negative. Fix this by casting each byte to u64 before shifting. Also fix the misaligned break statement while we are here. Example of the result can be seen here: Link: https://godbolt.org/z/zhY8d3595 It maybe not a real problem, but could be a issue in future.

So PAD needs to be configured as PULL UP with PULL Enable, no need SION. Correct it.
