Is .text 1 the same as .section???
.text 1 occurs in entry.S
Please tell me what it means?
It specifies a numeric subsection. It’s still part of the text section, but it will presumably be placed after the normal part of the text section. It’s being used here to place rarely used code out of line. It also means that straight-line flow of control skips to the next instance of .previous, without needing an extra JMP instruction. Tricky code. :-)
