[PATCH v3 02/10] ntdll/tests: Move NtMapViewOfSection tests from kernel32/tests

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

This can't work.  You also need the code inside START_TEST(virtual) to parse
the command line and actually do the sleeping.

Huw.

[PATCH v3 05/10] ntdll: Clarify NtMapViewOfSection zero_bits parameter semantic

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

[PATCH v3 06/10] ntdll: Add map_view_aligned function that handles memory alignment

[Rémi Bernon]

Instead of mask, this function takes top_down, zero_bits and alignment
(resp. high bits and low bits alignment constraints) parameters.

The map_view function is now just a wrapper around it with default
alignment values.

[PATCH v3 06/10] ntdll: Add map_view_aligned function that handles memory alignment

I don't think having two functions makes things clearer, especially as map_view()
itself is now only called twice.  Just swap mask for alignment in map_view()
and you're done.

To avoid spamming the list too much, could you just resend these first six
patches?

Huw.

[PATCH v3 07/10] ntdll: Add top_down parameter to virtual_map_section and map_image

[Rémi Bernon]

NtMapViewOfSection also accepts the MEM_TOP_DOWN parameter that can
be used in combination with zero_bits to map memory on the highest
possible address.

This is useful for the next patches so we can consistently fail
zero_bits tests.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

[PATCH v3 09/10] ntdll/tests: Use MEM_TOP_DOWN parameter to consistently fail zero_bits tests

[Rémi Bernon]

The todo_wine_if made the tests not really test anything, and one test
was succeeding when it shouldn't. Now we can actually remove the todo
when 1 zero_bits handling is implemented.

[PATCH v3 10/10] ntdll: Workaround NtAllocateVirtualMemory with zero_bits set to 1

[Rémi Bernon]

Implement the correct zero_bits behavior for this single case:
* Limit the search in reserved areas to the lower 2G range,
* Pass the MAP_32BIT flag to mmap as a fallback.

LuaJIT <= v2.0.5 for example, when running in 64bit, allocates its
memory in the lower 2GB memory region by using the zero_bits parameter.

This will fix this particular scenario, while trying to minimize the
changes on all the other cases.
