ca36c36b78 MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_phys
Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm
The approach taken is inspired by the sparse memory implementation: take a
certain number of high-order bits off the address them, use this as an
index into a table containing an offset to the desired address and add
it to the original value. There is a table for mapping physical addresses
to DMA addresses and another one for the reverse mapping. The table sizes
depend on how fine-grained the mappings need to be; Coarser granularity
less to smaller tables.  On a processor with 32-bit physical and DMA
addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays.
Each 32-byte cache line thus covers 64 MiB of address space.

Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to
dma_to_phys() to align with kernel usage.

[Ralf: Fixed silly build breakage due to stackoverflow warning caused by
huge array on stack.]

aec9222551 MIPS: BCM47xx: Really fix 128MB RAM problem
The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp.
84a6fcb368 (kernel.org) was wrong.

The BCM47xx architecture maps the ram into a 128MB address space. It
will be spaced there as often as goes into the 128MB. Detection tries to
find the position where the same memory is found. When reading beyond
128MB the processor will throw an exception. If 128MB RAM is installed,
it will not find a memory alias because it tries to read beyond the 128MB
border. Now it just assumes 128MB installed ram if it can not find an
alias.

4d2b11252b MIPS: Don't overflow cevt-r4k.c calculations at high clock rates.
The 'mult' element of struct clock_event_device must never be wider
than 32-bits.  If it were, it would get truncated when used by
clockevent_delta2ns() when this calls do_div().

We can meet this requirement by using clockevent_set_clock() to set
the MULT and SHIFT values.

8a22b9996b xen: drop xen_sched_clock in favour of using plain wallclock time
xen_sched_clock only counts unstolen time.  In principle this should
be useful to the Linux scheduler so that it knows how much time a process
actually consumed.  But in practice this doesn't work very well as the
scheduler expects the sched_clock time to be synchronized between
cpus.  It also uses sched_clock to measure the time a task spends
sleeping, in which case "unstolen time" isn't meaningful.

So just use plain xen_clocksource_read to return wallclock nanoseconds
for sched_clock.

Currently register_xenstore_notifier notifies the caller during the
registration itself if xenstore is believed to be ready. This behaviour
causes problems to PV on HVM guests, in which case callers should be
notified by xenbus_probe only after the platform pci driver is loaded.
We already make sure xenbus_probe is called at the right time, calling
it either from device_initcall (PV case) or from the platform pci
driver initialization (HVM case) so we don't need this additional
notification.

e3b5e0d552 powerpc/fsl_pci: add quirk for mpc8308 pcie bridge
This patch adds the quirk for PCIE controller found on Freescale MPC8308.
The quirk is the same as for other MPC83xx processors.

99d8238f5f powerpc/85xx: Cleanup QE initialization for MPC85xxMDS boards
The mpc85xx_mds_setup_arch() function is incomprehensible
and unmaintainable. Factor out all QE specific stuff into
mpc85xx_mds_qe_init() and mpc85xx_mds_reset_ucc_phys().

Also move QE stuff out of mpc85xx_mds_pic_init().

The diff is unreadable, but only because the code was so. ;-)
It should be better now, and less indented.

dee9ad718b powerpc/85xx: Fix booting for P1021MDS boards
P1021 processors have no dedicated ROM to store the QE microcode,
so the fimrware is stored externally, and it is U-Boot responsibility
to load it. It might be that the board is booting without QE, e.g.
currently U-Boot doesn't support QE for P1021MDS boards, which means
that QE isn't initialized, and so the board hangs early at boot.

This patch fixes the issue by marking QE as disabled and checking the
state in the probing code. U-Boot should fixup the state if it
initialized the QE.

bb863e85a7 powerpc/85xx: Fix SWIOTLB initalization for MPC85xxMDS boards
The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the
mpc85xx_mds_setup_arch() return early if no QE nodes present,
and so SWIOTLB is never initialized.

This patch fixes the issue by moving SWIOTLB code above
QE.

694f690d27 CRED: Fix RCU warning due to previous patch fixing __task_cred()'s checks
Commit 8f92054e7c ("CRED: Fix __task_cred()'s lockdep check and banner
comment") fixed the lockdep checks on __task_cred().  This has shown up
a place in the signalling code where a lock should be held - namely that
check_kill_permission() requires its callers to hold the RCU lock.

Fix group_send_sig_info() to get the RCU read lock around its call to
check_kill_permission().

Without this patch, the following warning can occur:

  ===================================================
  [ INFO: suspicious rcu_dereference_check() usage. ]

e75aa85892 block_dev: always serialize exclusive open attempts
bd_prepare_to_claim() incorrectly allowed multiple attempts for
exclusive open to progress in parallel if the attempting holders are
identical.  This triggered BUG_ON() as reported in the following bug.

  https://bugzilla.kernel.org/show_bug.cgi?id=16393

__bd_abort_claiming() is used to finish claiming blocks and doesn't
work if multiple openers are inside a claiming block.  Allowing
multiple parallel open attempts to continue doesn't gain anything as
those are serialized down in the call chain anyway.  Fix it by always
allowing only single open attempt in a claiming block.

This problem can easily be reproduced by adding a delay after
bd_prepare_to_claim() and attempting to mount two partitions of a
disk.

d9b68e5e88 parisc: pass through '\t' to early (iodc) console
The firmware handles '\t' internally, so stop trying to emulate it
(which, incidentally, had a bug in it.)

Fixes a really weird hang at bootup in rcu_bootup_announce, which,
as far as I can tell, is the first printk in the core kernel to use
a tab as the first character.
