Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

MIPS: Factor o32 specific code into signal_o32.c The commit ebb5e78cc634 ("MIPS: Initial implementation of a VDSO") caused building a 64 bit kernel with support for n32 and not o32 to produce a build error: arch/mips/kernel/signal32.c:415:11: error: ‘vdso_image_o32’ undeclared here (not in a function) .vdso = &vdso_image_o32, Fix this by moving the o32 specific code into signal_o32.c and updating the Makefile accordingly.

tree-wide: replace config_enabled() with IS_ENABLED() The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

Fix breakage in MIPS siginfo handling MIPS's siginfo handling has been broken since this commit: commit 574c4866e33d648520a8bd5bf6f573ea6e554e88 Author: Al Viro <viro@zeniv.linux.org.uk> Date: Sun Nov 25 22:24:19 2012 -0500 consolidate kernel-side struct sigaction declarations for 64-bit BE MIPS CPUs. The UAPI variant looks like this: struct sigaction { unsigned int sa_flags; __sighandler_t sa_handler; sigset_t sa_mask; }; but the core kernel's variant looks like this: struct sigaction { #ifndef __ARCH_HAS_ODD_SIGACTION __sighandler_t sa_handler; unsigned long sa_flags; #else unsigned long sa_flags; __sighandler_t sa_handler; #endif #ifdef __ARCH_HAS_SA_RESTORER __sigrestore_t sa_restorer; #endif sigset_t sa_mask; }; The problem is that sa_flags has been changed from an unsigned int to an unsigned long. Fix this by making sa_flags unsigned int if __ARCH_HAS_ODD_SIGACTION is defined. Whilst we're at it, rename __ARCH_HAS_ODD_SIGACTION to __ARCH_HAS_IRIX_SIGACTION.
