msm: Make CONFIG_STRICT_MEMORY_RWX even stricter

If CONFIG_STRICT_MEMORY_RWX was set, the first section (containing
the kernel page table and the initial code) and the section
containing the init code were both given RWX permission, which is
a potential security hole.

Pad the first section after the initial code (which will never
be executed when the MMU is on) to make the rest of the kernel
text start in the second section and make the first section RW.

Move some data which had ended up in the "init text"
section into the "init data" one, as this is RW, not RX.
Make the "init text" RX.

We will not free the section containing the "init text",
because if we do, the kernel will allocate memory for RW data there.

sync: Fix a race condition between release_obj and print_obj

Before this change, a timeline would only be removed from the timeline
list *after* the sync driver had its release_obj() called. However, the
driver's release_obj() may free resources needed by print_obj().

Although the timeline list is locked when print_obj() is called, it is
not locked when release_obj() is called. If one CPU was in print_obj()
when another was in release_obj(), the print_obj() may make unsafe
accesses.

It is not actually necessary to hold the timeline list lock when calling
release_obj() if the call is made after the timeline is unlinked from
the list, since there is no possibility another thread could be in --
or enter -- print_obj() for that timeline.

This change moves the release_obj() call to after the timeline is
unlinked, preventing the above race from occurring.
