H A Dprom_init.cdiff 8af1da40669609707303eecdb857f48a5ba5792d Tue May 29 14:20:01 CDT 2018 Mathieu Malaterre <malat@debian.org> powerpc/prom: Fix %u/%llx usage since prom_printf() change

In commit eae5f709a4d7 ("powerpc: Add __printf verification to
prom_printf") __printf attribute was added to prom_printf(), which
means GCC started warning about type/format mismatches. As part of
that commit we changed some "%lx" formats to "%llx" where the type is
actually unsigned long long.

Unfortunately prom_printf() doesn't know how to print "%llx", it just
prints a literal "lx", eg:

reserved memory map:
lx - lx
lx - lx

prom_printf() also doesn't know how to print "%u" (only "%lu"), it
just prints a literal "u", eg:

Max number of cores passed to firmware: u (NR_CPUS = 2048)

Instead of:

Max number of cores passed to firmware: 2048 (NR_CPUS = 2048)

This commit adds support for the missing formatters.
