This is required for kdump to work when loaded at at an address that
does not fall within the first TLB entry -- which can easily happen
because while the lower limit is enforced via reserved memory, which
doesn't affect how much is mapped, the upper limit is enforced via a
different mechanism that does. Thus, more TLB entries are needed than
would normally be used, as the total memory to be mapped might not be a
power of two.

Use an AS=1 trampoline TLB entry to allow all normal TLB1 entries to
be loaded at once. This avoids the need to keep the translation that
code is executing from in the same TLB entry in the final TLB
configuration as during early boot, which in turn is helpful for
relocatable kernels (e.g. kdump) where the kernel is not running from
what would be the first TLB entry.
On e6500, we limit map_mem_in_cams() to the primary hwthread of a
core (the boot cpu is always considered primary, as a kdump kernel
can be entered on any cpu). Each TLB only needs to be set up once,
and when we do, we don't want another thread to be running when we
create a temporary trampoline TLB1 entry.

Otherwise, because the top end of the crash kernel is treated as the
absolute top of memory rather than the beginning of a reserved region,
in-flight DMA from the previous kernel that targets areas above the
crash kernel can trigger a storm of PCI errors. We only do this for
kdump, not normal kexec, in case kexec is being used to upgrade to a
kernel that wants a different inbound memory map.

85xx currently uses the generic timebase sync mechanism when
CONFIG_KEXEC is enabled, because 32-bit 85xx kexec support does a hard
reset of each core. 64-bit 85xx kexec does not do this, so we neither
need nor want this (nor is the generic timebase sync code built on
ppc64).
FWIW, I don't like the fact that the hard reset is done on 32-bit
kexec, and I especially don't like the timebase sync being triggered
only on the presence of CONFIG_KEXEC rather than actually booting in
that environment, but that's beyond the scope of this patch...

Problems have been observed in coreint (EPR) mode if interrupts are
left pending (due to the lack of device quiescence with kdump) after
having tried to deliver to a CPU but unable to deliver due to MSR[EE]
-- interrupts no longer get reliably delivered in the new kernel. I
tried various ways of fixing it up inside the crash kernel itself, and
none worked (including resetting the entire mpic). Masking all
interrupts and issuing EOIs in the crashing kernel did help a lot of
the time, but the behavior was not consistent.
Thus, stick to standard IACK mode when kdump is a possibility.

This allows SMP kernels to work as kdump crash kernels. While crash
kernels don't really need to be SMP, this prevents things from breaking
if a user does it anyway (which is not something you want to only find
out once the main kernel has crashed in the field, especially if
whether it works or not depends on which cpu crashed).

It makes no sense that some Freescale device tree files are in fsl
directory while some others not. This patch move Freescale device tree
files into fsl folder. To do that the following two steps are made:
- Move Freescale device tree files into fsl folder.
- Update the include path in these files from "fsl/*.dtsi" to "*.dtsi".
Please add "fsl/" prefix when you make dtb using Makefile.

The paca display is already more than 24 lines, which can be problematic
if you have an old school 80x24 terminal, or more likely you are on a
virtual terminal which does not scroll for whatever reason.
This patch adds a new command "#", which takes a single (hex) numeric
argument: lines per page. It will cause the output of "dp" and "dpa"
to be broken into pages, if necessary.

The pseries build with PCI=n looks to have been broken for at least 5
years, and no one's noticed or cared.
Following the obvious breakages backward, the first commit I can find
that builds is the parent of 2eb4afb69ff3 ("powerpc/pci: Move pseries
code into pseries platform specific area") from April 2009.
A distro would never ship a PCI=n kernel, so it is only useful for folks
building custom kernels. Also on KVM the virtio devices appear on PCI,
so it would only be useful if you were building kernels specifically to
run on PowerVM and with no PCI devices.
The added code complexity, and testing load (which we've clearly not
been doing), is not justified by the small reduction in kernel size for
such a niche use case.
So just make PCI non-optional on pseries.

My recent commit d2036f30cfe1 ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.
This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.
The fix is simple, we need to look for the file under $(srctree).

We need to properly identify whether a hugepage is an explicit or
a transparent hugepage in follow_huge_addr(). We used to depend
on hugepage shift argument to do that. But in some case that can
result in wrong results. For ex:
On finding a transparent hugepage we set hugepage shift to PMD_SHIFT.
But we can end up clearing the thp pte, via pmdp_huge_get_and_clear.
We do prevent reusing the pfn page via the usage of
kick_all_cpus_sync(). But that happens after we updated the pte to 0.
Hence in follow_huge_addr() we can find hugepage shift set, but transparent
huge page check fail for a thp pte.
NOTE: We fixed a variant of this race against thp split in commit
691e95fd7396905a38d98919e9c150dbc3ea21a3
("powerpc/mm/thp: Make page table walk safe against thp split/collapse")
Without this patch, we may hit the BUG_ON(flags & FOLL_GET) in
