Re: [dpdk-dev] [PATCH v6 07/17] drivers: replace page size definitions with function

The page size is often retrieved from the macro PAGE_SIZE.
If PAGE_SIZE is not defined, it is either using hard coded default,
or getting the system value from the UNIX-only function sysconf().

Such definitions are replaced with the generic function
rte_mem_page_size() defined for each supported OS.

Removing PAGE_SIZE definitions will fix dlb drivers for musl libc,
because #ifdef checks were missing, causing redefinition errors.

Is the header file with the rte_mem_page_size() function missing from this
patch?
Also, rather than a function for this, would it not be better to keep it as
a macro as RTE_PAGE_SIZE, to keep it more in line with the macro people
expect to have available?
