Where does kernel stores it's registers while performing a context switch?

Oct. 7, 2017


      I want to know where the kernel stores it's registers while performing
a context switch on x86 architecture. In ARM I can see  struct
cpu_context_save in arch/arm/include/asm/thread_info.h but what about
x86/x86_64?

Where does kernel stores it's registers while performing a context switch?
