linux-toradex.git/arch/x86/kernel/trampoline_32.S, branch v3.4.70 Linux kernel for Apalis and Colibri modules x86, trampoline: Common infrastructure for low memory trampolines 2011-02-18T05:02:43+00:00 H. Peter Anvin hpa@linux.intel.com 2011-02-14T23:34:57+00:00 4822b7fc6d4870685a9feadfc348d48f5e47460a Common infrastructure for low memory trampolines. This code installs the trampolines permanently in low memory very early. It also permits multiple pieces of code to be used for this purpose. This code also introduces a standard infrastructure for computing symbol addresses in the trampoline code. The only change to the actual SMP trampolines themselves is that the 64-bit trampoline has been made reusable -- the previous version would overwrite the code with a status variable; this moves the status variable to a separate location.

Common infrastructure for low memory trampolines.  This code installs
the trampolines permanently in low memory very early.  It also permits
multiple pieces of code to be used for this purpose.

This code also introduces a standard infrastructure for computing
symbol addresses in the trampoline code.

The only change to the actual SMP trampolines themselves is that the
64-bit trampoline has been made reusable -- the previous version would
overwrite the code with a status variable; this moves the status
variable to a separate location.
