The existing logging macros are fairly large and converting the
macros to functions make the object code smaller.
Use %pV and __builtin_return_address(0) as appropriate.

You could add any multiple of 2^32/PNFS_SCSI_RANGE_SIZE to nr_iomaps and

This is a simple extension to the block layout driver to use SCSI
persistent reservations for access control and fencing, as well as
SCSI VPD pages for device identification.
For this we need to pass the nfs4_client to the proc_getdeviceinfo method
to generate the reservation key, and add a new fence_client method
to allow for fence actions in the layout driver.

This is a trivial extension to the block layout driver to support the
new SCSI layouts draft. There are three changes:
- device identifcation through the SCSI VPD page. This allows us to
directly use the udev generated persistent device names instead of
requiring an expensive lookup by crawling every block device node
in /dev and reading a signature for it.
- use of SCSI persistent reservations to protect device access and
allow for robust fencing. On the client sides this just means
registering and unregistering a server supplied key.
- an optimized LAYOUTCOMMIT payload that doesn't send unessecary
fields to the server.

mkspec is copying built kernel to temporrary location
/boot/vmlinuz-$KERNELRELEASE-rpm
and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.
Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.
Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
treated as if it set it to n.
Regression had been introduced by commit cfa98f ("kconfig: do not
override symbols already set"); what happens is that conf_read_simple()
does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
has conf_set_all_new_symbols() skip modules_sym.
It's pretty easy to fix - simply move that call of sym_calc_value()
into the callers, except for the ones in KCONFIG_ALLCONFIG handling.

With the introduction of the simple wait API we have two very
similar APIs in the kernel. For example wake_up() and swake_up()
is only one character away. Although the compiler will warn
happily the wrong usage it keeps on going an even links the kernel.
Thomas and Peter would rather like to see early missuses reported
as error early on.
In a first attempt we tried to wrap all swait and wait calls
into a macro which has an compile time type assertion. The result
was pretty ugly and wasn't able to catch all wrong usages.
woken_wake_function(), autoremove_wake_function() and wake_bit_function()
are assigned as function pointers. Wrapping them with a macro around is
not possible. Prefixing them with '_' was also not a real option
because there some users in the kernel which do use them as well.
All in all this attempt looked to intrusive and too ugly.
An alternative is to turn the pointer type check into an error which
catches wrong type uses. Obviously not only the swait/wait ones. That
isn't a bad thing either.

Under certain conditions, Kbuild shows "... is up to date" where
if_changed or friends are used.
For example, the incremental build of ARM64 Linux shows this message
when the kernel image has not been updated.
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CHK include/generated/bounds.h
CHK include/generated/timeconst.h
CHK include/generated/asm-offsets.h
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
CHK kernel/config_data.h
make[1]: `arch/arm64/boot/Image.gz' is up to date.
Building modules, stage 2.
MODPOST 0 modules
The following is the build rule in arch/arm64/boot/Makefile:
$(obj)/Image.gz: $(obj)/Image FORCE
$(call if_changed,gzip)
If the Image.gz is newer than the Image and the command line has not
changed (i.e., $(any-prereq) and $(arg-check) are both empty), the
build rule $(call if_changed,gzip) is evaluated to be empty, then
GNU Make reports the target is up to date. In order to make GNU Make
quiet, we need to give it something to do, for example, "@:". This
should be fixed in the Kbuild core part rather than in each Makefile.

Since the output of the invocation of scripts/kallsyms is piped directly
into the assembler, error messages it emits are visible on stderr, but
a non-zero return code is ignored, and the build simply proceeds in that
case. However, the resulting kernel is most likely broken, and will crash
at boot.
So instead, capture the output of kallsyms in a separate .S file, and pass
that to the assembler in a separate step.

No other kernel installation target moves the target directory out of
the way, even deleting an old version of it. These are destructive
operations, ones which the kernel build system should not be making.
This behaviour prevents being able to do:
make install INSTALL_PATH=/some/path/boot
make dtbs_install INSTALL_DTBS_PATH=/some/path/boot
As it causes the boot directory containing the kernel installed in
step 1 to be moved to /some/path/boot.old. Things get even more fun
if you do:
make install dtbs_install INSTALL_PATH=/some/path/boot INSTALL_DTBS_PATH=/some/path/boot
The kernel gets installed into /some/path/boot, then the directory gets
renamed to /some/path/boot.old, and a new directory created to hold the
dtbs. Even more fun if you supply -j2 when we end up with races in
make.
Remove this behaviour.
If this behaviour is required at installation time, this should be
done by the installation external to the kernel makefiles, just like
it would be done for 'make modules_install'.

Switch to the generic extable search and sort routines which were introduced
with commit a272858 from Ard Biesheuvel. This saves quite some memory in the
vmlinux binary with the 64bit kernel.

PA-RISC wants to sleep 5 seconds before panicking when panic_on_oops
is set, with no apparent reason. Remove this feature, since some users
may want their systems to fail as quickly as possible.
Users who want to delay reboot after panic can use PANIC_TIMEOUT.

On parisc and metag the stack grows upwards, so for those we need to
scan the stack downwards in order to calculate how much stack a process
has used.

The system calls alloc_hugepages() and free_hugepages() were introduced

on parisc, so let's drop them now.

Currently we disable preemption in copy_to_user_page; a behaviour that
we inherited from the 32-bit arm code. This was necessary for older
cores without broadcast data cache maintenance, and ensured that cache
lines were dirtied and cleaned by the same CPU. On these systems dirty
cache line migration was not possible, so this was sufficient to
guarantee coherency.
On contemporary systems, cache coherence protocols permit (dirty) cache
lines to migrate between CPUs as a result of speculation, prefetching,
and other behaviours. To account for this, in ARMv8 data cache
maintenance operations are broadcast and affect all data caches in the
domain associated with the VA (i.e. ISH for kernel and user mappings).
In __switch_to we ensure that tasks can be safely migrated in the middle
of a maintenance sequence, using a dsb(ish) to ensure prior explicit
memory accesses are observed and cache maintenance operations are
completed before a task can be run on another CPU.
Given the above, it is not necessary to disable preemption in
copy_to_user_page. This patch removes the preempt_{disable,enable}
calls, permitting preemption.

Commit 324420bf91f60582 ("arm64: add support for ioremap() block
mappings") added new p?d_set_huge functions which do the hard work to
generate and set a correct block entry.
These differ from open-coded huge page creation in the early page table
code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly
retained by mk_sect_prot() for any valid prot), but are otherwise
identical (and cannot fail on arm64).
For simplicity and consistency, make use of these in the initial page
table creation code.

The KASLR code incorrectly expects the contents of x18 to be preserved
across a call into C code, and uses it to stash the contents of SCTLR_EL1
before enabling the MMU. If the MMU needs to be disabled again to create
the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is
likely to crash the system if x18 has been clobbered by kasan_early_init()
or kaslr_early_init(). So use x22 instead, which is not in use so far in
head.S

pr_cont()
The printk() implementation has a limit of LOG_LINE_MAX (== 1024 - 32)
buffer per call which the arm64 mem_init() breaches when printing the
virtual memory layout with CONFIG_KASAN enabled. The result is that the
last line is no longer printed. This patch splits the call into a
pr_notice() + additional pr_cont() calls.

Commit f80fb3a3d50843a4 ("arm64: add support for kernel ASLR") missed a
DSB necessary to complete I-cache maintenance in the primary boot path,
and hence stale instructions may still be present in the I-cache and may
be executed until the I-cache maintenance naturally completes.
Since commit 8ec41987436d566f ("arm64: mm: ensure patched kernel text is
fetched from PoU"), all CPUs invalidate their I-caches after their MMU
is enabled. Prior a CPU's MMU having been enabled, arbitrary lines may
have been fetched from the PoC into I-caches. We never patch text
expected to be executed with the MMU off. Thus, it is unnecessary to
perform broadcast I-cache maintenance in the primary boot path.
This patch reduces the scope of the I-cache maintenance to the local
CPU, and adds the missing DSB with similar scope, matching prior
maintenance in the primary boot path.

The implementation of macro inv_entry refers to its 'el' argument without
the required leading backslash, which results in an undefined symbol
'el' to be passed into the kernel_entry macro rather than the index of
the exception level as intended.
This undefined symbol strangely enough does not result in build failures,
although it is visible in vmlinux:
$ nm -n vmlinux |head
U el
0000000000000000 A _kernel_flags_le_hi32
0000000000000000 A _kernel_offset_le_hi32
0000000000000000 A _kernel_size_le_hi32
000000000000000a A _kernel_flags_le_lo32
.....
However, it does result in incorrect code being generated for invalid
exceptions taken from EL0, since the argument check in kernel_entry
assumes EL1 if its argument does not equal '0'.

- The i.MX changes were sent relatively late, and had a dependency on
the clk tree, so I delayed that a bit. Support for the new i.MX6qp
SoC and a couple of new boards is added in this branch.
- Uniphier renames a few files to match the final product names that
were decided by the company, kudos to the kernel developer(s) for
getting support upstream before the product release. Also two
boards are added. The patches were posted early enough and nice
overall, but we forgot to apply them and decided to give it some
more time in linux-next
- at91 has two small bug fixes"
