Ryusuke Konishi 973bec34bf nilfs2: fix sync silent failure
As of 32a88aa1, __sync_filesystem() will return 0 if s_bdi is not set.
And nilfs does not set s_bdi anywhere.  I noticed this problem by the
warning introduced by the recent commit 5129a469 ("Catch filesystem
lacking s_bdi").

 WARNING: at fs/super.c:959 vfs_kern_mount+0xc5/0x14e()

This ensures to set s_bdi for nilfs and fixes the sync silent failure.

Commit e67a807 ("x86: Fix 'reservetop=' functionality") added a
fixup_early_ioremap() call to parse_reservetop() and declared it
in io.h.

But asm/io.h was only included indirectly - and on some configs
not at all, causing a build failure on those configs.

Wu Zhangjin 64fc74f5f6 MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jump
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed
the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.

The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong.  Avoids the problem via telling the assembler to not use the $at
register.

Wu Zhangjin 622844bf0b MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDS
As documented in the  Loongson 2F User Manual [2, 3], the old Loongson2F
series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds
in the kernel and binutils.  This issue has been rectified in Loongson 2F
series 2F03 so no workarounds needed.

Now that the workarounds [1] adding the the -mfix-loongson2f-nop and
-mfix-loongson2f-jump options have been comitted to the binutils the CVS
repository), we can add the workarounds in the kernel.

The workarounds have no significant side effect on the system but may
decrease performance so we control them through a a new
CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable
it as necessary.

Sebastian Andrzej Siewior 4f81b01a30 MIPS: Use CKSEG1ADDR for uncached handler
"MIPS: Calculate proper ebase value for 64-bit kernels"
9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp.
f6be75d03c (kernel.org) broke some 64-bit
MIPS systems.

Before this we were using XKPHYS/cached as ebase and computed the uncached
xphsys/unchached address for that area. After that commit ebase became a
32-bit compat address and convert does not work anymore.  We now should use
CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

David Daney 1ec56329ff MIPS: Check for accesses beyond the end of the PGD.
For some combinations of PAGE_SIZE and vmbits, it is possible to have
userspace access that are beyond what is covered by the PGD, but within
vmbits.  Such an access would cause the TLB refill handler to load garbage
values for PMD and PTE potentially giving userspace access to parts of the
physical address space to which it is not entitled.

In the TLB refill hot path, we add a single dsrl instruction so we can
check if any bits outside of the range covered by the PGD are set.  In
the vmalloc side we then separate the bad case from the normal vmalloc
case and call tlb_do_page_fault_0 if warranted.  This slows us down a
bit, but has the benefit of yielding deterministic behavior.

[Ralf: Fixed build error for 32-bit kernels.]

Yury Polyanskiy ce384d83d0 MIPS: die() does not call die notifier chain
The MIPS implementation of die() forgets to call notify_die() and thus notifiers
registered via register_die_notifier() are not called.  This results in kgdb not
being activated on exceptions.

The only subtlety is that notify_die declares its regs argument w/o const, so
the const had to be removed from mips die() as well.

[Ralf: Fixed build error for SGI IP22 and IP28 platforms.]

Sebastian Andrzej Siewior fcf3ca4c3d MIPS: Swarm, Littlesur: Enable PATA platform driver.
According to include/asm/sibyte/swarm.h both systems provide a
platform device for the ide controler. Until now the IDE subsystem was
used which is deprecated by now. The same structure can be used with the
PATA driver.

Manuel Lauss 0000a53901 MIPS: DB1200: PCMCIA card detection must not be auto-enabled.
Same issues as SD card detection:  One of both is always triggering and the
handlers take care to shut it up and enable the other.  To avoid messages
about "unbalanced interrupt enable/disable" they must not be automatically
enabled when initally requested.

This was not an issue with the db1200_defconfig due to fortunate timings;
on a build without network chip support the warnings appear.

The field was changed in d9b26352 aka ("x86, setup: Store the boot

before this extra field got introduced.

While here, the other two boards are also converted to C99 initializer.

David Daney c8f3cc0b65 MIPS: Don't vmap things at address zero.
In the 64-bit kernel we use swapper_pg_dir for three different things.

1) xuseg mappings for kernel threads.

2) vmap mappings for all kernel-space accesses in xkseg.

3) vmap mappings for kernel modules in ksseg (kseg2).

Due to how the TLB refill handlers work, any mapping established in
xkseg or ksseg will also establish a xuseg mapping that should never
be used by the kernel.

In order to be able to use exceptions to trap NULL pointer
dereferences, we need to ensure that nothing is mapped at address
zero.  Since vmap mappings in xkseg are reflected in xuseg, this means
we need to ensure that there are no vmap mappings established at the
start of xkseg.  So we move back VMALLOC_START to avoid establishing
vmap mappings at the start of xkseg.

commit 5a0e3ad6af
    Author: Tejun Heo <tj@kernel.org>
    Date:   Wed Mar 24 17:04:11 2010 +0900

        include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

Since a while the few headers included don't drag in <linux/kernel.h>
anymore, thus no more prototype of printk() resulting in:

Seems like pdev->bus->self == NULL. I haven't touched pci in a long time
so I'm trying to remember what this means (no pcie bridge perhaps?)

The patch below fixes the oops for me.
