Pull arm64 updates from Catalin Marinas:
"Here are the main arm64 updates for 4.6. There are some relatively
intrusive changes to support KASLR, the reworking of the kernel
virtual memory layout and initial page table creation.
Summary:
- Initial page table creation reworked to avoid breaking large block
mappings (huge pages) into smaller ones. The ARM architecture
requires break-before-make in such cases to avoid TLB conflicts but
that's not always possible on live page tables
- Kernel virtual memory layout: the kernel image is no longer linked
to the bottom of the linear mapping (PAGE_OFFSET) but at the bottom
of the vmalloc space, allowing the kernel to be loaded (nearly)
anywhere in physical RAM
- Kernel ASLR: position independent kernel Image and modules being
randomly mapped in the vmalloc space with the randomness is
provided by UEFI (efi_get_random_bytes() patches merged via the
arm64 tree, acked by Matt Fleming)
- Implement relative exception tables for arm64, required by KASLR
(initial code for ARCH_HAS_RELATIVE_EXTABLE added to lib/extable.c
but actual x86 conversion to deferred to 4.7 because of the merge
dependencies)
- Support for the User Access Override feature of ARMv8.2: this
allows uaccess functions (get_user etc.) to be implemented using
LDTR/STTR instructions. Such instructions, when run by the kernel,
perform unprivileged accesses adding an extra level of protection.
The set_fs() macro is used to "upgrade" such instruction to
privileged accesses via the UAO bit
- Half-precision floating point support (part of ARMv8.2)
- Optimisations for CPUs with or without a hardware prefetcher (using
run-time code patching)
- copy_page performance improvement to deal with 128 bytes at a time
- Sanity checks on the CPU capabilities (via CPUID) to prevent
incompatible secondary CPUs from being brought up (e.g. weird
big.LITTLE configurations)
- valid_user_regs() reworked for better sanity check of the
sigcontext information (restored pstate information)
- ACPI parking protocol implementation
- CONFIG_DEBUG_RODATA enabled by default
- VDSO code marked as read-only
- DEBUG_PAGEALLOC support
- ARCH_HAS_UBSAN_SANITIZE_ALL enabled
- Erratum workaround Cavium ThunderX SoC
- set_pte_at() fix for PROT_NONE mappings

We need to remove the now obsolete WARN_ON(req->sk), since req->sk

Implement basic character sets for the '%[' conversion specifier.
The '%[' conversion specifier matches a nonempty sequence of characters
from the specified set of accepted (or with '^', rejected) characters
between the brackets. The substring matched is to be made up of
characters in (or not in) the set. This is useful for matching
substrings that are delimited by something other than spaces.
This implementation differs from its glibc counterpart in the following ways:
(1) No support for character ranges (e.g., 'a-z' or '0-9')
(2) The hyphen '-' is not a special character
(3) The closing bracket ']' cannot be matched
(4) No support (yet) for discarding matching input ('%*[')
The bitmap code is largely based upon sample code which was provided by
Rasmus.
The motivation for adding character set support to sscanf originally
stemmed from the kernel livepatching project. An ongoing patchset
utilizes new livepatch Elf symbol and section names to store important
metadata livepatch needs to properly apply its patches. Such metadata
is stored in these section and symbol names as substrings delimited by
periods '.' and commas ','. For example, a livepatch symbol name might
look like this:
.klp.sym.vmlinux.printk,0
However, sscanf currently can only extract "substrings" delimited by
whitespace using the "%s" specifier. Thus for the above symbol name,
one cannot not use sscanf() to extract substrings "vmlinux" or
"printk", for example. A number of discussions on the livepatch
mailing list dealing with string parsing code for extracting these '.'
and ',' delimited substrings eventually led to the conclusion that such
code would be completely unnecessary if the kernel sscanf() supported
character sets. Thus only a single sscanf() call would be necessary to
extract these substrings. In addition, such an addition to sscanf()
could benefit other areas of the kernel that might have a similar need
in the future.

The traceoff_on_warning option doesn't have any effect on s390, powerpc,
arm64, parisc, and sh because there are two different types of WARN
implementations:
1) The above mentioned architectures treat WARN() as a special case of a
BUG() exception. They handle warnings in report_bug() in lib/bug.c.
2) All other architectures just call warn_slowpath_*() directly. Their
warnings are handled in warn_slowpath_common() in kernel/panic.c.
Support traceoff_on_warning on all architectures and prevent any future
divergence by using a single common function to emit the warning.
Also remove the '()' from '%pS()', because the parentheses look funky:

With huge pages, it is convenient to have the radix tree be able to
return an entry that covers multiple indices. Previous attempts to deal
with the problem have involved inserting N duplicate entries, which is a
waste of memory and leads to problems trying to handle aliased tags, or
probing the tree multiple times to find alternative entries which might
cover the requested index.
This approach inserts one canonical entry into the tree for a given
range of indices, and may also insert other entries in order to ensure
that lookups find the canonical entry.
This solution only tolerates inserting powers of two that are greater
than the fanout of the tree. If we wish to expand the radix tree's
abilities to support large-ish pages that is less than the fanout at the
penultimate level of the tree, then we would need to add one more step
in lookup to ensure that any sibling nodes in the final level of the
tree are dereferenced and we return the canonical entry that they
reference.

Christian Borntraeger reported that panic_on_warn doesn't have any
effect on s390.
The panic_on_warn feature was introduced with 9e3961a097 ("kernel: add
panic_on_warn"). However it did care only for the case when
WANT_WARN_ON_SLOWPATH is defined. This is turn is only the case for
architectures which do not have an own __WARN_TAINT defined.
Other architectures which do have __WARN_TAINT defined call report_bug()
for warnings within lib/bug.c which does not call panic() in case
panic_on_warn is set.
Let's simply enable the panic_on_warn feature by adding the same code
like it was added to warn_slowpath_common() in panic.c.
This enables panic_on_warn also for arm64, parisc, powerpc, s390 and sh.
