Analyze and fix the following issue in the Linux kernel code: x86/purgatory: Switch to the position-independent small code model
Problem Details: On x86, the ordinary, position dependent small and kernel code models only support placement of the executable in 32-bit addressable memory, due to the use of 32-bit signed immediates to generate references to global variables. For the kernel, this implies that all global variables must reside in the t...
