Subject[PATCH v2 0/8] powerpc/vdso32 enhancement and optimisation
Date
This series:
- adds getcpu()
- adds coarse clocks in clock_gettime
- fixes and adds all clocks in clock_getres
- optimises the retrieval of the datapage address
- optimises the cache functions

It puts together the three patches sent out earlier allthought they
were not presented as a series, hence the 'v2' tag for now.

v2:
- Used named labels in patch 2
- Added patch from Vincenzo to fix clock_getres() (patch 3)
- Removed unnecessary label in patch 4 as suggested by Segher
- Added patches 5 to 8

Christophe Leroy (8):
powerpc/32: Add VDSO version of getcpu
powerpc/vdso32: Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE
powerpc: Fix vDSO clock_getres()
powerpc/vdso32: inline __get_datapage()
powerpc/vdso32: Don't read cache line size from the datapage on PPC32.
powerpc/vdso32: use LOAD_REG_IMMEDIATE()
powerpc/vdso32: implement clock_getres entirely
powerpc/vdso32: miscellaneous optimisations
