Hi
compiling 2.4.26-pre1 appears this:

system.c: In function `acpi_power_off':
system.c:98: warning: implicit declaration of function `acpi_system_save_state'
system.c: At top level:
system.c:178: warning: type mismatch with previous implicit declaration
system.c:98: warning: previous implicit declaration of `acpi_system_save_state'
system.c:178: warning: `acpi_system_save_state' was previously implicitly declared to return `int'
system.c: In function `acpi_power_off':
system.c:98: warning: implicit declaration of function `acpi_system_save_state'
system.c: At top level:
system.c:178: warning: type mismatch with previous implicit declaration
system.c:98: warning: previous implicit declaration of `acpi_system_save_state'
system.c:178: warning: `acpi_system_save_state' was previously implicitly declared to return `int'

this could be resolved with this trivial patch 

Thanks
