In order to reduce copy/paste of functions across architectures and then
make riscv hugetlb port (and future ports) simpler and smaller, this
patchset intends to factorize the numerous hugetlb primitives that are
defined across all the architectures.
Except for prepare_hugepage_range, this patchset moves the versions that
are just pass-through to standard pte primitives into
asm-generic/hugetlb.h by using the same #ifdef semantic that can be found
in asm-generic/pgtable.h, i.e. __HAVE_ARCH_***.
s390 architecture has not been tackled in this serie since it does not use
asm-generic/hugetlb.h at all.
This patchset has been compiled on all addressed architectures with
success (except for parisc, but the problem does not come from this
series).
This patch (of 11):
asm-generic/hugetlb.h proposes generic implementations of hugetlb related
functions: use __HAVE_ARCH_HUGE* defines in order to make arch specific
implementations of hugetlb functions consistent with pgtable.h scheme.

Replace bootmem allocator with memblock and enable use of NO_BOOTMEM like
on most other architectures.
Alpha gets the description of the physical memory from the firmware as an
array of memory clusters. Each cluster that is not reserved by the
firmware is added to memblock.memory.
Once the memblock.memory is set up, we reserve the kernel and initrd pages
with memblock reserve.
Since we don't need the bootmem bitmap anymore, the code that finds an
appropriate place is removed.
The conversion does not take care of NUMA support which is marked broken
for more than 10 years now.

The unicore32 architecture already supports memblock and uses it for some
early memory reservations, e.g initrd and the page tables.
At some point unicore32 allocates the bootmem bitmap from the memblock and
then hands over the memory reservations from memblock to bootmem.
This patch removes the bootmem initialization and leaves memblock as the
only boot time memory manager for unicore32.

ARM64 has asm implementation of memchr(), memcmp(), str[r]chr(),
str[n]cmp(), str[n]len(). KASAN don't see memory accesses in asm code,
thus it can potentially miss many bugs.
Ifdef out __HAVE_ARCH_* defines of these functions when KASAN is enabled,
so the generic implementations from lib/string.c will be used.
We can't just remove the asm functions because efistub uses them. And we
can't have two non-weak functions either, so declare the asm functions as
weak.

Right now if we get a corrupted user stack frame we do a
do_exit(SIGILL) which is not helpful.
If under a debugger, this behavior causes the inferior process to
exit. So the register and other state cannot be examined at the time
of the event.
Instead, conditionally log a rate limited kernel log message and then
force a SIGSEGV.
With bits and ideas borrowed (as usual) from powerpc.

Pull powerpc updates from Michael Ellerman:
"Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of
fairly complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for
each process and preload them on context switch. Leading to a 27%
speedup for our context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print
more debug information when they occur, and try to continue running
by flushing the SLB and reloading, rather than treating them as
fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on
64-bit Book3S. We only support up to 512TB as regular system
memory, otherwise the percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task
canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are
presented to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE
flags.
- Add a driver for the PAPR SCM (storage class memory) interface,
allowing guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we
need to use a trampoline to get to ftrace_caller().
And many other smaller enhancements and cleanups.

- Debugfs support for the Intel VT-d driver.
When enabled, it now also exposes some of its internal data

Fix a bug introduced by the creation of flush_all_to_thread() for
processors that have SPE (Signal Processing Engine) and use it to
compute floating-point operations.
>From userspace perspective, the problem was seen in attempts of
computing floating-point operations which should generate exceptions.
For example:
fork();
float x = 0.0 / 0.0;
isnan(x); // forked process returns False (should be True)
The operation above also should always cause the SPEFSCR FINV bit to
be set. However, the SPE floating-point exceptions were turned off
after a fork().
Kernel versions prior to the bug used flush_spe_to_thread(), which
first saves SPEFSCR register values in tsk->thread and then calls
giveup_spe(tsk).
After commit 579e633e764e, the save_all() function was called first
to giveup_spe(), and then the SPEFSCR register values were saved in
tsk->thread. This would save the SPEFSCR register values after
disabling SPE for that thread, causing the bug described above.

This changes the KVM code that emulates the decrementer function to do
the conversion of decrementer values to time intervals in nanoseconds
by calling the tb_to_ns() function exported by the powerpc timer code,
in preference to open-coded arithmetic using values from the
decrementer_clockevent struct. Similarly, the HV-KVM code that did
the same conversion using arithmetic on tb_ticks_per_sec also now
uses tb_to_ns().

Later when vmlinux.bin is produced from vmlinux, .vmlinux.info section
is removed. But elf vmlinux file, even though it is not bootable anymore,
used for debugging and loadable segments overlap should be avoided.
Utilize special ":NONE" phdr specification to avoid adding .vmlinux.info
into loadable data segment. Also set .vmlinux.info section type to INFO,
which allows to get a not-loadable info CONTENTS section.
Since minimal supported version of binutils 2.20 does not have
--dump-section objcopy option, make .vmlinux.info section loadable during
info.bin creation to get actual section contents.

There are only two 64-bit architecture ports that have a 32-bit
suseconds_t: sparc64 and parisc64. I've encountered a number of problems
with this, while trying to get a proper 64-bit time_t working on 32-bit
architectures. Having a 32-bit suseconds_t combined with a 64-bit time_t
means that we get extra padding in data structures that may leak kernel
stack data to user space, and it breaks all code that assumes that
timespec and timeval have the same layout.
While we can't change sparc64, it seems that glibc on parisc64 has always
set suseconds_t to 'long', and the current version would give incorrect
results for gettimeofday() and many other interfaces: timestamps passed
from user space into the kernel result in tv_usec being always zero
(the lower bits contain the intended value but are ignored) while data
passed from the kernel to user space contains either zeroes or random
data in tv_usec.
Based on that, it seems best to change the user API in the kernel in
an incompatible way to match what glibc expects.
Note that the distros I could find (gentoo and debian) all just
have 32-bit user space, which does not suffer from this problem.

Pull RISC-V updates from Palmer Dabbelt:
"This patch set contains a lot (at least, for me) of improvements to
the RISC-V kernel port:
- The removal of some cacheinfo values that were bogus.
- On systems with F but without D the kernel will not show the F
extension to userspace, as it isn't actually supported.
- Support for futexes.
- Removal of some unused code.
- Cleanup of some menuconfig entries.
- Support for systems without a floating-point unit, and for building
kernels that will never use the floating-point unit.
- More fixes to the RV32I port, which regressed again. It's really
time to get this into a regression test somewhere so I stop
breaking it. Thanks to Zong for resurrecting it again!
- Various fixes that resulted from a year old review of our original
patch set that I finally got around to.
- Various improvements to SMP support, largely based around having
switched to logical hart numbering, as well as some interrupt
improvements. This one is in the same patch set as above, thanks to
Atish for sheparding everything though as my patch set was a bit of
a mess.
I'm pretty sure this is our largest patch set since the original
kernel contribution, and it's certainly the one with the most
contributors. While I don't have anything else I know I'm going to
submit for the merge window, I would be somewhat surprised if I didn't
screw anything up.
Thanks for the help, everyone!"

Assembler messages:
