H A Dentry-header.S22 @ Most of the stack format comes from struct pt_regs, but with
79 @ exception happend that is either on the main or the process stack.
80 @ Bit 2 of EXC_RETURN stored in the lr register specifies which stack
91 @ Linux expects to have irqs off. Do it here before taking stack space
103 @ calculate the original stack pointer value.
106 @ The cpu might automatically 8-byte align the stack. Bit 9
108 @ another 32-bit value is included in the stack.

H A Dentry_64.rst47 the IDT entries push an error code onto the stack; others don't.
48 IDT entries using the IST alternative stack mechanism need their own
49 magic to get the stack frames right. (You can find some
68 stack, from the CS of the ptregs area of the kernel stack::
88 use the faster check: the stack will be a reliable indicator of
96 stack but before we executed SWAPGS, then the only safe way to check
104 - Interrupt entry from user mode will switch off the IST stack.
