We used to use kmalloc (more exactly, krealloc()) for creating and growing the temporary buffer for text proc write. It can grow up to 16kB, and it's already a bit doubtful whether it's always safe to use kmalloc(). With the recent addition of kvmalloc(), we can have a better chance for succeed of memory allocation, so let's switch to that new API.
