Subject: [PATCH] [PATCH v3] Introduce the mdf_pfn_t type.
|
|
|
|
Replace unsigned long long with mdf_pfn_t where:
|
|
|
|
a. the variable denotes a PFN
|
|
b. the variable is a number of pages
|
|
|
|
The number of pages is converted to a mdf_pfn_t, because it is a result
|
|
of subtracting two PFNs or incremented in a loop over a range of PFNs,
|
|
so it can get as large as a PFN.
|
|
|
|
Note: The mdf_ (i.e. makedumpfile) prefix is used to prevent possible
|
|
conflicts with other software that defines a pfn_t type.
