Commit ebd97be6 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option')
removed the ARCH_SUPPORTS_MSI option which architectures could select
to indicate that they support MSI. Now, all architectures are supposed
to build fine when MSI support is enabled: instead of having the
architecture tell *when* MSI support can be used, it's up to the
architecture code to ensure that MSI support can be enabled.

On x86, commit ebd97be6 removed the following line:

  select ARCH_SUPPORTS_MSI if (X86_LOCAL_APIC && X86_IO_APIC)

Which meant that MSI support was only available when the local APIC
and I/O APIC were enabled. While this is always true on SMP or x86-64,
it is not necessarily the case on i386 !SMP.

The below patch makes sure that the local APIC and I/O APIC support is
always enabled when MSI support is enabled. To do so, it:

 * Ensures the X86_UP_APIC option is not visible when PCI_MSI is
   enabled. This is the option that allows, on UP machines, to enable
   or not the APIC support. It is already not visible on SMP systems,
   or x86-64 systems, for example. We're simply also making it
   invisible on i386 MSI systems.

 * Ensures that the X86_LOCAL_APIC and X86_IO_APIC options are 'y'
   when PCI_MSI is enabled.

Notice that this change requires a change in drivers/iommu/Kconfig to
avoid a recursive Kconfig dependencey. The AMD_IOMMU option selects
PCI_MSI, but was depending on X86_IO_APIC. This dependency is no
longer needed: as soon as PCI_MSI is selected, the presence of
X86_IO_APIC is guaranteed. Moreover, the AMD_IOMMU already depended on
X86_64, which already guaranteed that X86_IO_APIC was enabled, so this
dependency was anyway redundant.

  powerpc: Fix parameter clobber in csum_partial_copy_generic()

When we do a treclaim or trecheckpoint we end up running with userspace
PPR and DSCR values.  Currently we don't do anything special to avoid
running with user values which could cause a severe performance
degradation.

This patch moves the PPR and DSCR save and restore around treclaim and
trecheckpoint so that we run with user values for a much shorter period.
More care is taken with the PPR as it's impact is greater than the DSCR.

This is similar to user exceptions, where we run HTM_MEDIUM early to
ensure that we don't run with a userspace PPR values in the kernel.

Commit 4df48999 "Add power8 EBB support" included a bug in the handling
of the FAB_CRESP_MATCH and FAB_TYPE_MATCH fields.

These values are pulled out of the event code using EVENT_THR_CTL_SHIFT,
however we were then or'ing that value directly into MMCR1.

This meant we were failing to set the FAB fields correctly, and also
potentially corrupting the value for PMC4SEL. Leading to no counts for
the FAB events and incorrect counts for PMC4.

The fix is simply to shift left the FAB value correctly before or'ing it
with MMCR1.

Under heavy (DLPAR?) stress, we tripped this panic() in
arch/powerpc/kernel/iommu.c::iommu_init_table():

	page = alloc_pages_node(nid, GFP_ATOMIC, get_order(sz));
	if (!page)
		panic("iommu_init_table: Can't allocate %ld bytes\n", sz);

Before the panic() we got a page allocation failure for an order-2
allocation. There appears to be memory free, but perhaps not in the
ATOMIC context. I looked through all the call-sites of
iommu_init_table() and didn't see any obvious reason to need an ATOMIC
allocation. Most call-sites in fact have an explicit GFP_KERNEL
allocation shortly before the call to iommu_init_table(), indicating we
are not in an atomic context. There is some indirection for some paths,
but I didn't see any locks indicating that GFP_KERNEL is inappropriate.

With this change under the same conditions, we have not been able to
reproduce the panic.

Unfortunately, it fails to restore them upon error exit from this loop,
which results in silent corruption of these registers in the presumably
rare event of an access exception within that loop.

Previous commit 46723bfa... introduced a new config option
HAVE_BOOTMEM_INFO_NODE that ended up breaking memory hot-remove for ppc
when sparse vmemmap is not defined.

This patch defines HAVE_BOOTMEM_INFO_NODE for ppc and adds the call to
register_page_bootmem_info_node. Without this we get a BUG_ON for memory
hot remove in put_page_bootmem().

This also adds a stub for register_page_bootmem_memmap to allow ppc to build
with sparse vmemmap defined. Leaving this as a stub is fine since the same
vmemmap addresses are also handled in vmemmap_populate and as such are
properly mapped.

IORESOURCE_BUSY is used to mark temporary driver mem-resources
instead of global regions. This suppresses warnings if regions
overlap with a region marked as BUSY.

This was always the case for VESA/VGA/EFI framebuffer regions so
do the same for simplefb regions. The reason we do this is to
allow device handover to real GPU drivers like
i915/radeon/nouveau which get the same regions via PCI BARs.

Maybe at some point we will be able to unregister platform
devices properly during the handover. In this case the simplefb
region would get removed before the new region is created.
However, this is currently not the case and would require rather
huge changes in remove_conflicting_framebuffers(). Add the BUSY
marker now and try to eventually rewrite the handover for a next release.

Also see kernel/resource.c for more information:

  /*
   * if a resource is "BUSY", it's not a hardware resource
   * but a driver mapping of such a resource; we don't want
   * to warn for those; some drivers legitimately map only
   * partial hardware resources. (example: vesafb)
   */

This suppresses warnings like:

Previously, when a signal was registered with SA_SIGINFO, parameters 2
and 3 of the signal handler were written to registers r1 and r2 before
the register set was saved. This led to corruption of these two
registers after returning from the signal handler (the wrong values were
restored).
With this patch, registers are now saved before any parameters are
passed, thus maintaining the processor state from before signal entry.

Commit ebd97be6 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option')
removes the ARCH_SUPPORTS_MSI Kconfig option that allowed
architectures to indicate whether they support PCI MSI or not. Now,
PCI MSI support can be compiled in on any architecture thanks to the
use of weak functions thanks to 4287d824 ('PCI: use weak functions
for MSI arch-specific functions').

So, architecture specific code is now responsible to ensure that its
PCI MSI code builds in all cases, or be appropriately conditionally
compiled.

On Sparc, the MSI support is only provided for Sparc64, so the
ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and
not for the Sparc architecture as a whole. Therefore, removing
ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y,
because the Sparc-specific MSI code is not designed to be built on
Sparc32.

To solve this, this commit ensures that the Sparc MSI code is only
built on Sparc64. This is done thanks to a new Kconfig Makefile helper
option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The
SPARC64_PCI_MSI option is an hidden option that is true when both
Sparc64 PCI support is enabled and MSI is enabled. The
arch/sparc/kernel/pci_msi.c file is now only built when
SPARC64_PCI_MSI is true.

The include/asm-generic/hugetlb.h stubs that just vector huge_pte_*()
calls to the pte_*() implementations won't work in certain situations.

x86 and sparc, for example, return "unsigned long" from the bit
checks, and just go "return pte_val(pte) & PTE_BIT_FOO;"

But since huge_pte_*() returns 'int', if any high bits on 64-bit are
relevant, they get chopped off.

The net effect is that we can loop forever trying to COW a huge page,
because the huge_pte_write() check signals false all the time.

On my MacBook Air lfb_size is 4M, which makes the bitshit
overflow (to 256GB - larger than 32 bits), meaning we fall
back to efifb unnecessarily.

Cast to u64 to avoid the overflow.

Pull networking changes from David Miller:

 1) Multiply in netfilter IPVS can overflow when calculating destination
    weight.  From Simon Kirby.

 2) Use after free fixes in IPVS from Julian Anastasov.

 3) SFC driver bug fixes from Daniel Pieczko.

 4) Memory leak in pcan_usb_core failure paths, from Alexey Khoroshilov.

 5) Locking and encapsulation fixes to serial line CAN driver, from
    Andrew Naujoks.

 6) Duplex and VF handling fixes to bnx2x driver from Yaniv Rosner,
    Eilon Greenstein, and Ariel Elior.

 7) In lapb, if no other packets are outstanding, T1 timeouts actually
    stall things and no packet gets sent.  Fix from Josselin Costanzi.

 8) ICMP redirects should not make it to the socket error queues, from
    Duan Jiong.

 9) Fix bugs in skge DMA mapping error handling, from Nikulas Patocka.

10) Fix setting of VLAN priority field on via-rhine driver, from Roget
    Luethi.

11) Fix TX stalls and VLAN promisc programming in be2net driver from
    Ajit Khaparde.

    support code, from Ming Lei.

13) Fix races in netdevice teardown wrt.  network namespace closing.
    From Eric W.  Biederman.

14) Fix potential missed initialization of net_secret if not TCP
    connections are openned.  From Eric Dumazet.

15) Cinterion PLXX product ID in qmi_wwan driver is wrong, from
    Aleksander Morgado.

16) skb_cow_head() can change skb->data and thus packet header pointers,
    don't use stale ip_hdr reference in ip_tunnel code.

17) Backend state transition handling fixes in xen-netback, from Paul
    Durrant.

18) Packet offset for AH protocol is handled wrong in flow dissector,
    from Eric Dumazet.

    in the queues, fix from Eric Dumazet.

20) Fix performance regressions introduced by TCP Small Queues.  From
    Eric Dumazet.

21) IPV6 GRE tunneling code calculates max_headroom incorrectly, from
    Hannes Frederic Sowa.

22) Multicast timer handlers in ipv4 and ipv6 can be the last and final
    reference to the ipv4/ipv6 specific network device state, so use the
    reference put that will check and release the object if the
    reference hits zero.  From Salam Noureddine.

23) Fix memory corruption in ip_tunnel driver, and use skb_push()
    instead of __skb_push() so that similar bugs are less hard to find.
    From Steffen Klassert.

24) Add forgotten hookup of rtnl_ops in SIT and ip6tnl drivers, from
    Nicolas Dichtel.

25) fq scheduler doesn't accurately rate limit in certain circumstances,
