Subject: [PATCH 75/89] libparted: Add Intel Rapid Start Technology partition
flag.
This adds support for the irst partition type flag. Sets the type to
0x84 on MS-DOS and D3BFE2DE-3DAF-11DF-BA-40-E3A556D89593 on GPT.
* NEWS (New Features): Mention it.
* doc/C/parted.8: Document irst flag.
* doc/parted.texti: Document irst flag.
* include/parted/disk.in.h (_PedPartitionFlag): Add PED_PARTITION_IRST flag

** New Features
+ Added new partition type flag, irst, for use with Intel Rapid Start
+ Technology. On MS-DOS disk labels it sets the type to 0x84 and on GPT
+ it sets the GUID to D3BFE2DE-3DAF-11DF-BA-40-E3A556D89593.
+
You can now choose to ignore errors about partitions that overlap,
or are longer than the disk. This allows you to use parted to
repair the problem.
