Currently, there are several locations where an attempt to reserve more
PEBs for bad PEB handling is made, with the same code being duplicated.
Harmonize it by introducing 'ubi_update_reserved()'.
Also, improve the debug message issued, making it more descriptive.

* SMALL_PRINTERS_MODE
* EXTENDED_MODE
spear320-evb board is designed for EXTENDED_MODE only, hence it does not
boot correctly in current form where pinctrl part for some devices fail.
Configure and boot the SPEAr320 evaluation board in EXTENDED_MODE.

sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl
register bit no. 23:25, with following possibilities
0XX: pll1_clk
10X: sys_synth_clk
110: pll2_clk
111: pll3_clk
Out of several possibilities (h/w wise) to select same clock parent for
sys_clk, current clock implementation was considering just one value.
When bootloader programmed different (valid) value to select a clock
parent then Linux breaks.
Here, we try to include all possibilities which can lead to same
clock selection thus making Linux independent of bootloader selection
values.

In ancient times, the messenger could both initiate and accept connections.
An artifact if that was data structures to store/process an incoming
ceph_msg_connect request and send an outgoing ceph_msg_connect_reply.
Sadly, the negotiation code was referencing those structures and ignoring
important information (like the peer's connect_seq) from the correct ones.
Among other things, this fixes tight reconnect loops where the server sends
RETRY_SESSION and we (the client) retries with the same connect_seq as last
time. This bug pretty easily triggered by injecting socket failures on the
MDS and running some fs workload like workunits/direct_io/test_sync_io.

We want it to be possible for target_submit_cmd() to return errors up
to its fabric module callers. For now just update the prototype to
return an int, and update all callers to handle non-zero return values
as an error.
This is immediately useful for tcm_qla2xxx to fix a long-standing active
I/O session shutdown race, but tcm_fc, usb-gadget, and sbp-target the
fabric maintainers need to check + ACK that handling a target_submit_cmd()
failure due to session shutdown does not introduce regressions

mm: fix lost kswapd wakeup in kswapd_stop()
m32r: make memset() global for CONFIG_KERNEL_BZIP2=y
m32r: add memcpy() for CONFIG_KERNEL_GZIP=y
m32r: consistently use "suffix-$(...)"
m32r: fix 'fix breakage from "m32r: use generic ptrace_resume code"' fallout
m32r: fix pull clearing RESTORE_SIGMASK into block_sigmask() fallout
m32r: remove duplicate definition of PTRACE_O_TRACESYSGOOD
mn10300: fix "pull clearing RESTORE_SIGMASK into block_sigmask()" fallout
bootmem: make ___alloc_bootmem_node_nopanic() really nopanic
Offlining memory may block forever, waiting for kswapd() to wake up
because kswapd() does not check the event kthread->should_stop before
sleeping.
The proper pattern, from Documentation/memory-barriers.txt, is:
--- waker ---
event_indicated = 1;
wake_up_process(event_daemon);
--- sleeper ---
for (;;) {
set_current_state(TASK_UNINTERRUPTIBLE);
if (event_indicated)
break;
schedule();
}
set_current_state() may be wrapped by:
prepare_to_wait();
In the kswapd() case, event_indicated is kthread->should_stop.
=== offlining memory (waker) ===
kswapd_stop()
kthread_stop()
kthread->should_stop = 1
wake_up_process()
wait_for_completion()
=== kswapd_try_to_sleep (sleeper) ===
kswapd_try_to_sleep()
prepare_to_wait()
.
.
schedule()
.
.
finish_wait()
The schedule() needs to be protected by a test of kthread->should_stop,
which is wrapped by kthread_should_stop().
Reproducer:
Do heavy file I/O in background.
Do a memory offline/online in a tight loop

| f5bf18fa22 again. The problem was not a panicking version on
| allocation failure but when the usemap size was too large such that
| goal + size > limit triggers the BUG_ON in the bootmem allocator. So
| we need a version that passes limit ONLY if the usemap is smaller than
| the section.
after checking the code, the name of ___alloc_bootmem_node_nopanic()
does not reflect the fact.
Make bootmem really not panic.
Hope will kill bootmem sooner.
