mmap.2: Describe treatment of 'offset' for MAP_ANONYMOUS
...
The manpage claimed that the offset argument is ignored, and when
I interpreted that as "I don't need to set that register when
doing the syscall", I got failures. I was able to spot two reasons
for that:
What I probably ran into:
At least on x86-64, sys_mmap (in arch/x86/kernel/sys_x86_64.c)
always checks that the offset is page-aligned, even for
MAP_ANONYMOUS.
Another one, could probably trigger on 32-bit x86:
In do_mmap(), there is a check to ensure that pgoff together with
the allocation length won't cause an overflow, even for
MAP_ANONYMOUS.
Document that userspace should pass in zero, since that's
probably what everyone is doing already. (It would also be
possible to describe the constraints on the offset more
carefully, but zero works, and nobody should need to pass in
anything else.)

mmap2: Clarify MAP_POPULATE
...
David Rientjes has noticed that MAP_POPULATE wording might promise
much more than the kernel actually provides and intend to provide.
The primary usage of the flag is to pre-fault the range. There is
no guarantee that no major faults will happen later on. The pages
might have been reclaimed by the time the process tries to access
them.

mmap.2: Clarify MAP_LOCKED semantics
...
MAP_LOCKED had a subtly different semantic from mmap(2)+mlock(2)
since it has been introduced.
mlock(2) fails if the memory range cannot get populated to
guarantee that no future major faults will happen on the range.
mmap(MAP_LOCKED) on the other hand silently succeeds even if
the range was populated only partially.
Fixing this subtle difference in the kernel is rather awkward
because the memory population happens after mm locks have been
dropped and so the cleanup before returning failure (munlock)
could operate on something else than the originally mapped area.
E.g. speculative userspace page fault handler catching SEGV and
doing mmap(fault_addr, MAP_FIXED|MAP_LOCKED) might discard portion
of a racing mmap and lead to lost data. Although it is not clear
whether such a usage would be valid, mmap page doesn't explicitly
describe requirements for threaded applications so we cannot
exclude this possibility.
This patch makes the semantic of MAP_LOCKED explicit and suggests
using mmap + mlock as the only way to guarantee no later major
page faults.

The "ABI" doesn't really convey anything significant in
the title. These subsections are about describing differences
between the kernel and (g)libc interfaces.

mmap.2: Remove text that implies that munmap() syncs MAP_SHARED mapping to file
...
The existing text in this page:
MAP_SHARED Share this mapping. Updates to the mapping
are visible to other processes that map this
file, and are carried through to the underly‐
ing file. The file may not actually be
updated until msync(2) or munmap() is called.
implies that munmap() will sync the mapping to the underlying
file. POSIX doesn't require this, and some light reading of the
code and some light testing (fsync() after munmap() of a large
file) also indicates that Linux doesn't do this.

mmap.2: Add note about partial page in BUGS section
...
This adds a note about Linux behavior with partial page at the end
of the object. The problem here is that a page that contains only
part of a file (because the file size is not multiple of PAGE_SIZE)
stays in page cache even after the mapping is unmapped and the file
is closed. So if some process dirties such page, other mappings
will see the changes rather than zeroes.
I've also attached a reproducer which is a stripped down version of
the LTP test. The child creates a file of the size of PAGE_SIZE/2,
maps it, changes the content after the PAGE_SIZE/2. The parent
waits for the child to exit, maps the same file, and checks the
content after PAGE_SIZE/2. Uncommenting the msync() makes the test
succeed.

mmap.2: Loosen language around how 'addr' hint is interpreted
...
Mel Gorman reported that in Linux 2.6.27, 'addr' is rounded
down to a page boundary.
Before kernel 2.6.26, if 'addr' was taken as a hint, it was
rounded up to the next page boundary. Since Linux 2.6.24,
it is rounded down. Therefore, loosen the description of
this point to say that the address is rounded to "a nearby
page boundary".

MAP_POPULATE supports both file and anonymous mappings.

009df872f7
Format casts so that there is a non-breaking space after the
...
type, and remove unnecessary parentheses around the casted value.
Thus, for example, the following:
.IR "(size_t) (\-1)" .
becomes:
.IR "(size_t)\ \-1" .
