powerpc: Fix dl-procinfo HWCAP
|
|
|
c65238 |
|
|
|
c65238 |
HWCAP-related code should had been updated when the 32 bits of HWCAP were
|
|
|
c65238 |
used. This patch updates the code in dl-procinfo.h to loop through all
|
|
|
c65238 |
the 32 bits in HWCAP and updates _dl_powerpc_cap_flags accordingly.
