There are two data types: "struct vm_struct" and "struct vm_stack" that
have the same local variable names: vm_stack, or vm, or s, which makes the
code confusing to read.
Change the code so the naming is consistent:
struct vm_struct is always called vm_area
struct vm_stack is always called vm_stack
One change altering vfree(vm_stack) to vfree(vm_area->addr) may look like
a semantic change but it is not: vm_area->addr points to the vm_stack.
This was done to improve readability.
[linus.walleij@linaro.org: rebased and added new users of the variable names, address review comments]
