powerpc/xive: Define xive_do_source_eoi as static

2018-11-25T06:11:21+00:00

Sparse shows that xive_do_source_eoi() file is defined without any declaration, thus, it should be a static function. arch/powerpc/sysdev/xive/common.c:312:6: warning: symbol 'xive_do_source_eoi' was not declared. Should it be static? This patch simply turns this symbol into static. Signed-off-by: Breno Leitao Signed-off-by: Michael Ellerman

powerpc: Add -Werror at arch/powerpc level

2018-10-18T13:56:17+00:00

Back when I added -Werror in commit ba55bd74360e ("powerpc: Add configurable -Werror for arch/powerpc") I did it by adding it to most of the arch Makefiles. At the time we excluded math-emu, because apparently it didn't build cleanly. But that seems to have been fixed somewhere in the interim. So move the -Werror addition to the top-level of the arch, this saves us from repeating it in every Makefile and means we won't forget to add it to any new sub-dirs. Signed-off-by: Michael Ellerman

powerpc: remove redundant 'default n' from Kconfig-s

2018-10-13T11:21:25+00:00

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ... Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Michael Ellerman

powerpc/xive: Use xive_cpu->chip_id instead of looking it up again

2018-09-19T11:58:09+00:00

Function xive_native_get_ipi() might use chip_id without it being initialized, if the CPU node is not found, as reported by smatch: error: uninitialized symbol 'chip_id' As suggested by Cédric, we can use xc->chip_id instead of consulting the device tree for chip id, which is safe since xive_prepare_cpu() should have initialized ->chip_id by the time xive_native_get_ipi() is called.

powerpc/xive: Remove xive_kexec_teardown_cpu()

powerpc/xive: Remove now useless pr_debug statements

2018-08-07T11:49:27+00:00

Those overly verbose statement in the setup of the pool VP aren't particularly useful (esp. considering we don't actually use the pool, we configure it bcs HW requires it only). So remove them which improves the code readability. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc/64s: Remove POWER9 DD1 support

POWER9 DD1 was never a product. It is no longer supported by upstream firmware, and it is not effectively supported in Linux due to lack of testing. Signed-off-by: Nicholas Piggin Reviewed-by: Michael Ellerman [mpe: Remove arch_make_huge_pte() entirely] Signed-off-by: Michael Ellerman
