* fhandler.h (class fhandler_base): Declare fixup_mmap_after_fork
with additional flags parameter. Change offset parameter to _off64_t.
(class fhandler_disk_file): Ditto.
(class fhandler_dev_mem): Ditto.
* fhandler_mem.cc (fhandler_dev_mem::fixup_mmap_after_fork):
Accomodate new parameters.
* mmap.cc: Include ntdll.h.
(class mmap_record): Add flags member.
(mmap_record::mmap_record): Add flags parameter.
(mmap_record::get_flags): New method.
(class map): Add next_anon_addr member to store next anonymous mapping
address suggestion.
(map::get_next_anon_addr): New method.
(map::set_next_anon_addr): New method.
(mmap64): Don't align offset and length to granularity in case of
MAP_ANONYMOUS on NT. Check for already existing mapping only on 9x.
Call mmap_record::mmap_record with additional flags argument.
(fhandler_base::fixup_mmap_after_fork): Accomodate new parameters.
(fhandler_disk_file::mmap): Use NtMapViewOfSection with
AT_ROUND_TO_PAGE flag for anonymous mappings on NT. If addr is NULL,
try to map adjacent to previous mapping.
(fhandler_disk_file::fixup_mmap_after_fork): Add flags argument.
Change offset parameter to _off64_t. Use NtMapViewOfSection to
re-create anonymous mappings on NT.
(fixup_mmaps_after_fork): Accomodate new parameters when calling
fhandler's fixup_mmaps_after_fork function.
* ntdll.h (AT_ROUND_TO_PAGE): New define.
