Yes, this adds a little bloat to the other configs, but not much: text data bss dec hex filename 839 41 0 880 370 arch/ia64/kernel/acpi-ext.o Before: text data bss dec hex filename 10952753 1299212 1334241 13586206 cf4f1e vmlinux After: text data bss dec hex filename 10953739 1299084 1334241 13587064 cf5278 vmlinux (gdb) p 13587064 - 13586206 $2 = 858 Seems like a small price to pay for the benefit of not having to think so hard about the multitude of ia64 configs when reading code/Makefiles.

Unfortunately, the ia64_simdefconfig does not turn on CONFIG_ACPI, and we get build errors. The fix described in $subject seems to be the most sensible way to untangle the mess. The other issue is that acpi_get_sysname() is required for all configs, most of which define CONFIG_ACPI, but are not CONFIG_IA64_GENERIC. Turn it into an inline to cover the "non generic" ia64 configs; to prevent a duplicate definition build error, we need to wrap the definition in acpi.o inside an #ifdef. Finally, move the pm_idle and pm_power_off exports into process.c (which is always built), similar to other architectures, and allow the sim defconfig to link.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This has been broken since May 2008 when Al Viro killed altroot support. Since nobody has complained, it would appear that there are no users of this code (A plausible theory since the main OSVs that support ia64 prefer to use the IA32-EL software emulation).

The problem is that local data generates GOTOFF relocations, which means we can't relocate the data relative to the text segment. Global data, on the other hand, goes through the GOT, and can be relocated anywhere. Unfortunately, with the new decompressors, this presents a problem since they declare static data within functions, and this leads to stack overflow. Fix this by separating out the decompressor code into a separate file, and removing 'static' from BSS data in misc.c. Also, discard the .data section - this means that should we end up with read/write initialized data, the decompressor will fail to link and the problem will be obvious.
