So technically there is nothing wrong with adding a pinned page to the
swap cache, but the pinning obviously means that the page can't actually
be free'd right now anyway, so it's a bit pointless.
However, the real problem is not with it being a bit pointless: the real
issue is that after we've added it to the swap cache, we'll try to unmap
the page. That will succeed, because the code in mm/rmap.c doesn't know
or care about pinned pages.
Even the unmapping isn't fatal per se, since the page will stay around
in memory due to the pinning, and we do hold the connection to it using
the swap cache. But when we then touch it next and take a page fault,
the logic in do_swap_page() will map it back into the process as a
possibly read-only page, and we'll then break the page association on
the next COW fault.
Honestly, this issue could have been fixed in any of those other places:
(a) we could refuse to unmap a pinned page (which makes conceptual
sense), or (b) we could make sure to re-map a pinned page writably in
do_swap_page(), or (c) we could just make do_wp_page() not COW the
pinned page (which was what we historically did before that "mm:
do_wp_page() simplification" commit).
But while all of them are equally valid models for breaking this chain,
not putting pinned pages into the swap cache in the first place is the
simplest one by far.
It's also the safest one: the reason why do_wp_page() was changed in the
first place was that getting the "can I re-use this page" wrong is so
fraught with errors. If you do it wrong, you end up with an incorrectly
shared page.
As a result, using "page_maybe_dma_pinned()" in either do_wp_page() or
do_swap_page() would be a serious bug since it is only a (very good)
heuristic. Re-using the page requires a hard black-and-white rule with
no room for ambiguity.
In contrast, saying "this page is very likely dma pinned, so let's not
add it to the swap cache and try to unmap it" is an obviously safe thing
to do, and if the heuristic might very rarely be a false positive, no
harm is done.

Pull RISC-V fixes from Palmer Dabbelt:
"There are a few more fixes than a normal rc4, largely due to the

clock drivers may not be initialized.
- fix sifive,uart0 driver to properly display the baud rate. A fix to
initialize MPIE that allows interrupts to be processed during
system calls.
- avoid erronously begin tracing IRQs when interrupts are disabled,
which at least triggers suprious lockdep failures.
- workaround for a warning related to calling smp_processor_id()
while preemptible. The warning itself is suprious on currently
availiable systems.
- properly include the generic time VDSO calls. A fix to our kasan
address mapping. A fix to the HiFive Unleashed device tree, which
allows the Ethernet PHY to be properly initialized by Linux (as
opposed to relying on the bootloader).
- defconfig update to include SiFive's GPIO driver, which is present
on the HiFive Unleashed and necessary to initialize the PHY.
- avoid allocating memory while initializing reserved memory.
- avoid allocating the last 4K of memory, as pointers there alias
with syscall errors.
There are also two cleanups that should have no functional effect but
do fix build warnings:
- drop a duplicated definition of PAGE_KERNEL_EXEC.

Turning a pinned page read-only breaks the pinning after COW. Don't do it.
The whole "track page soft dirty" state doesn't work with pinned pages
anyway, since the page might be dirtied by the pinning entity without
ever being noticed in the page tables.

Linux kernel can only map 1GB of address space for RV32 as the page offset
is set to 0xC0000000. The current description in the Kconfig is confusing
as it indicates that RV32 can support 2GB of physical memory. That is
simply not true for current kernel. In future, a 2GB split support can be
added to allow 2GB physical address space.

Currently, linux kernel can not use last 4k bytes of addressable space
because IS_ERR_VALUE macro treats those as an error. This will be an issue
for RV32 as any memblock allocator potentially allocate chunk of memory
from the end of DRAM (2GB) leading bad address error even though the
address was technically valid.
Fix this issue by limiting the memblock if available memory spans the
entire address space.

This is also unnecessary as we can pre-compute the total memblocks required
for each memory region and allocate it before the loop. It save precious
boot time not going through memblock allocation code every time.

If we enter with requests pending and performm cancelations, we'll have
a different inflight count before and after calling prepare_to_wait().
This causes the loop to restart. If we actually ended up canceling
everything, or everything completed in-between, then we'll break out
of the loop without calling finish_wait() on the waitqueue. This can
trigger a warning on exit_signals(), as we leave the task state in
TASK_UNINTERRUPTIBLE.
Put a finish_wait() after the loop to catch that case.

As of now it doesn't consider cgroups when collecting shadow stats and
metrics so counter values from different cgroups will be saved in a same
slot. This resulted in incorrect numbers when those cgroups have
different workloads.
For example, let's look at the scenario below: cgroups A and C runs same
workload which burns a cpu while cgroup B runs a light workload.
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
3,958,116,522 cycles A
6,722,650,929 instructions A # 2.53 insn per cycle
1,132,741 cycles B
571,743 instructions B # 0.00 insn per cycle
4,007,799,935 cycles C
6,793,181,523 instructions C # 2.56 insn per cycle
1.001050869 seconds time elapsed
When I run 'perf stat' with single workload, it usually shows IPC around
1.7. We can verify it (6,722,650,929.0 / 3,958,116,522 = 1.698) for cgroup A.
But in this case, since cgroups are ignored, cycles are averaged so it
used the lower value for IPC calculation and resulted in around 2.5.
avg cycle: (3958116522 + 1132741 + 4007799935) / 3 = 2655683066
IPC (A) : 6722650929 / 2655683066 = 2.531
IPC (B) : 571743 / 2655683066 = 0.0002
IPC (C) : 6793181523 / 2655683066 = 2.557
We can simply compare cgroup pointers in the evsel and it'll be NULL
when cgroups are not specified. With this patch, I can see correct
numbers like below:
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
4,171,051,687 cycles A
7,219,793,922 instructions A # 1.73 insn per cycle
1,051,189 cycles B
583,102 instructions B # 0.55 insn per cycle

To pass more info to the saved_value in the runtime_stat, add a new
struct runtime_stat_data. Currently it only has 'ctx' field but later
patch will add more.
Note that we intentionally pass 0 as ctx to clock-related events for
compatibility. It was already there in a few places. So move the code
into the saved_value_lookup() explicitly and add a comment.

In the fast commit, it adds REQ_FUA and REQ_PREFLUSH on each fast
commit block when barrier is enabled. However, in recovery phase,
ext4 compares CRC value in the tail. So it is sufficient to add
REQ_FUA and REQ_PREFLUSH on the block that has tail.

We got a "deleted inode referenced" warning cross our fsstress test. The
bug can be reproduced easily with following steps:
cd /dev/shm
mkdir test/
fallocate -l 128M img
mkfs.ext4 -b 1024 img
mount img test/
dd if=/dev/zero of=test/foo bs=1M count=128
mkdir test/dir/ && cd test/dir/
for ((i=0;i<1000;i++)); do touch file$i; done # consume all block
cd ~ && renameat2(AT_FDCWD, /dev/shm/test/dir/file1, AT_FDCWD,
/dev/shm/test/dir/dst_file, RENAME_WHITEOUT) # ext4_add_entry in
ext4_rename will return ENOSPC!!
cd /dev/shm/ && umount test/ && mount img test/ && ls -li test/dir/file1
We will get the output:
"ls: cannot access 'test/dir/file1': Structure needs cleaning"
and the dmesg show:
"EXT4-fs error (device loop0): ext4_lookup:1626: inode #2049: comm ls:
deleted inode referenced: 139"
ext4_rename will create a special inode for whiteout and use this 'ino'
to replace the source file's dir entry 'ino'. Once error happens
latter(the error above was the ENOSPC return from ext4_add_entry in
ext4_rename since all space has been consumed), the cleanup do drop the
nlink for whiteout, but forget to restore 'ino' with source file. This
will trigger the bug describle as above.

Right now io_flush_timeouts() checks if the current number of events
is equal to ->timeout.target_seq, but this will miss some timeouts if
there have been more than 1 event added since the last time they were
flushed (possible in io_submit_flush_completions(), for example). Fix
it by recording the last sequence at which timeouts were flushed so
that the number of events seen can be compared to the number of events
needed without overflow.

The kbuild test robot reports that when building with W=1, GCC will warn
for a couple of missing prototypes in syscall.c:
| arch/arm64/kernel/syscall.c:157:6: warning: no previous prototype for 'do_el0_svc' [-Wmissing-prototypes]
| 157 | void do_el0_svc(struct pt_regs *regs)
| | ^~~~~~~~~~
| arch/arm64/kernel/syscall.c:164:6: warning: no previous prototype for 'do_el0_svc_compat' [-Wmissing-prototypes]
| 164 | void do_el0_svc_compat(struct pt_regs *regs)
| | ^~~~~~~~~~~~~~~~~
While this isn't a functional problem, as a general policy we should
include the prototype for functions wherever possible to catch any
accidental divergence between the prototype and implementation. Here we
can easily include <asm/exception.h>, so let's do so.
While there are a number of warnings elsewhere and some warnings enabled
under W=1 are of questionable benefit, this change helps to make the
code more robust as it evolved and reduces the noise somewhat, so it
seems worthwhile.

GCC versions >= 4.9 and < 5.1 have been shown to emit memory references
beyond the stack pointer, resulting in memory corruption if an interrupt
is taken after the stack pointer has been adjusted but before the
reference has been executed. This leads to subtle, infrequent data
corruption such as the EXT4 problems reported by Russell King at the
link below.
Life is too short for buggy compilers, so raise the minimum GCC version
required by arm64 to 5.1.
