Subject: directly use kmalloc() and kfree() in init/initramfs.c
From: Thomas Petazzoni <[EMAIL PROTECTED]>
Instead of using the malloc() and free() wrappers needed by the
lib/inflate.c code for allocations, simply use kmalloc() and kfree() in the
initramfs code. This is needed for a further lib/inflate.c-related cleanup
patch that will remove the malloc() and free() functions.
Take that opportunity to remove the useless kmalloc() return value
cast.
Based on work done by Matt Mackall.
