Details? The ones you sent were 32bit issues (with 1024 bytes frame-size-warning): fs/select.c:991:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] arch/parisc/kernel/inventory.c:359:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] Helge >> >> Helge >> >> [PATCH] parisc: Fix too large frame size warnings >> >> The parisc architecture requires larger stack frames than most other >> architectures on 32-bit kernels. >> Increase the default to 1280 bytes for parisc to avoid warnings in >> do_sys_poll() and pat_memconfig() functions. >> >> Signed-off-by: Helge Deller >> >> diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug >> index b19c491cbc4e..2689b7c50c52 100644 >> --- a/lib/Kconfig.debug >> +++ b/lib/Kconfig.debug >> @@ -219,7 +219,8 @@ config FRAME_WARN >> range 0 8192 >> default 0 if KASAN >> default 2048 if GCC_PLUGIN_LATENT_ENTROPY >> - default 1024 if !64BIT >> + default 1280 if (!64BIT && PARISC) >> + default 1024 if (!64BIT && !PARISC) >> default 2048 if 64BIT >> help >> Tell gcc to warn at build time for stack frames larger than this. >> >
