Remove MODULES dependency by creating module subsystem indepdent
text_alloc() and text_memfree() to allocate space for executable code.
Right now one has to compile modules support only to enable kprobes. This
incrases the barrier to use them in test kernels and I'd guess also in some
embedded kernels (the former is my use case).
v2:
* Added the missing cover letter.
Jarkko Sakkinen (3):
module: Rename module_alloc() to text_alloc() and move to kernel
proper
module: Add lock_modules() and unlock_modules()
kprobes: Flag out CONFIG_MODULES dependent code
