release_one_tty(tty) can be called when tty still has a reference
to pgrp/session. In this case we leak the pid.

* 'sh/for-2.6.34' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
sh: Fix up the SH-3 build for recent TLB changes.
sh: export return_address() symbol.
sh: Enable the mmu in start_secondary()
sh: Fix FDPIC binary loader
arch/sh/kernel: Use set_cpus_allowed_ptr

sh: update the TLB replacement counter for entry wiring.

While the MMUCR.URB and ITLB/UTLB differentiation works fine for all SH-4
and later TLBs, these features are absent on SH-3. This splits out
local_flush_tlb_all() in to SH-4 and PTEAEX copies while restoring the
old SH-3 one, subsequently fixing up the build.
This will probably want some further reordering and tidying in the
future, but that's out of scope at present.

proc_oom_score(task) has a reference to task_struct, but that is all.
If this task was already released before we take tasklist_lock
- we can't use task->group_leader, it points to nowhere
- it is not safe to call badness() even if this task is
->group_leader, has_intersects_mems_allowed() assumes
it is safe to iterate over ->thread_group list.
- even worse, badness() can hit ->signal == NULL
Add the pid_alive() check to ensure __unhash_process() was not called.
Also, use "task" instead of task->group_leader. badness() should return
the same result for any sub-thread. Currently this is not true, but
this should be changed anyway.

When the system has no lmb bram, main memory should be start from
zero because of microblaze vectors.
DTS fragment could look like:
DDR2_SDRAM: memory@0 {
device_type = "memory";
reg = < 0x0 0x10000000 >;
} ;
Then you have to setup CONFIG_KERNEL_BASE_ADDR=0 which caused
that kernel physical start address will be zero. On reset vector place
will be jump to 0x100 and on 0x100 starts kernel text.
You have to solve how to load the kernel before cpu starts.
Tested with XMD.
