Hi,
I am just curious to know if somebody uses kexec preserve context path. I
have never used it personally and I don't know anybody who makes use of it.
Is it an unused code and should it be ripped out?
Thanks
Vivek

Hi Vivek,
Related commit is:

"The features of this patch can be used as a general method to call program in
physical mode (paging turning off). This can be used to call BIOS code under
Linux."
Maybe someone from Intel still uses this...
