+Subject: [PATCH 01/10] linux-user: Use #if to only call validate_guest_space
+ for 32-bit ARM target
+
+Instead of defining a bogus validate_guest_space that always returns 1 on
+targets other than 32-bit ARM, use #if blocks to only call it on 32-bit ARM
+targets. This makes the "normal" flow control clearer.

+init_guest_commpage is a much more honest description of what the function

+Subject: [PATCH 04/10] linux-user: init_guest_space: Correctly handle
+ guest_start in commpage initialization
+
+init_guest_commpage needs to check if the mapped space, which ends at
+real_start+real_size overlaps with where it needs to put the commpage,
+which is (assuming sane qemu_host_page_size) guest_base + 0xffff000, where
+guest_base is real_start - guest_start.
+
+ [guest_base][ 0xffff0000 ][commpage]
+ [guest_base][guest_start][real_size] [commpage]
+ [ real_start ][real_size] [commpage]
+ ^
+ fail if this gap < 0
+
+Since init_guest_commpage wants to do everything relative to guest_base
+(rather than real_start), it obviously needs to be comparing 0xffff0000
+against guest_start+real_size, not just real_size.
+
+This bug has been present since 806d102141b99d4f1e55a97d68b7ea8c8ba3129f in
+2012, but guest_start is usually 0, and prior to v2.11 real_size was
+usually much smaller than 0xffff0000, so it was uncommon for it to have
+made a difference.

+Subject: [PATCH 05/10] linux-user: init_guest_space: Clarify page alignment
+ logic
+
+There are 3 parts to this change:
+ - Add a comment showing the relative sizes and positions of the blocks of
+ memory
+ - introduce and use new aligned_{start,size} instead of adjusting
+ real_{start_size}
+ - When we clean up (on failure), munmap(real_start, real_size) instead of
+ munmap(aligned_start, aligned_size). It *shouldn't* make any
+ difference, but I will admit that this does mean we are making the
+ syscall with different values, so this isn't quite a no-op patch.

+ we'll reject it
+
+If the ensure-alignment code gets triggered, then the
+"if (host_start && real_start != current_start)" check will always trigger,
+so save 2 syscalls and put that check first.
+
+Note that we can't just switch to using MAP_FIXED for that check, because
+then we couldn't differentiate between a failure because "there isn't
+enough space" and "there isn't enough space *here*".

+Cc: paul@codesourcery.com
+Subject: [PATCH 10/10] linux-user: init_guest_space: Try to make ARM
+ space+commpage continuous
+
+At a fixed distance after the usable memory that init_guest_space maps, for
+32-bit ARM targets we also need to map a commpage. The normal
+init_guest_space logic doesn't keep this in mind when searching for an
+address range.
+
+If !host_start, then try to find a big continuous segment where we can put
+both the usable memory and the commpage; we then munmap that segment and
+set current_start to that address; and let the normal code mmap the usable
+memory and the commpage separately. That is: if we don't have hint of
+where to start looking for memory, come up with one that is better than
+NULL. Depending on host_size and guest_start, there may or may not be a
+gap between the usable memory and the commpage, so this is slightly more
+restrictive than it needs to be; but it's only a hint, so that's OK.
+
+We only do that for !host start, because if host_start, then either:
+ - we got an address passed in with -B, in which case we don't want to
+ interfere with what the user said;
+ - or host_start is based off of the ELF image's loaddr. The check "if
+ (host_start && real_start != current_start)" suggests that we really
+ want lowest available address that is >= loaddr. I don't know why that
+ is, but I'm trusting that Paul Brook knew what he was doing when he
+ wrote the original version of that check in
+ c581deda322080e8beb88b2e468d4af54454e4b3 way back in 2010.
