* Implement support for page sizes > 4KB * Check and work around more alignment issues * Was not meant to change this * Use MemoryBlock.GetPageSize() value for signal handler code * Do not take the path for private allocations if host supports 4KB pages * Add Flags attribute on MemoryMapFlags * Fix dirty region size with 16kb pages Would accidentally report a size that was too high (generally 16k instead of 4k, uploading 4x as much data) Co-authored-by: riperiperi <rhy3756547@hotmail.com>
