* kbuild: simplified warning report in modpostSam Ravnborg2008-01-281-52/+52
| | | | | | | | | Refactor code so the warning report function does nothing else than reporting warnings. As a side effect some other code paths were cleaned up by this. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: introduce a few helpers in modpostSam Ravnborg2008-01-281-35/+38
| | | | | | | Introducing helpers to retreive symbol and section names cleaned up the code a bit. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: use simpler section mismatch warnings in modpostSam Ravnborg2008-01-281-40/+16
| | | | | | | | | The typical layout is now: WARNING: vmlinux.o(.text+0x372ec): Section mismatch: reference to .devinit.text:pci_scan_one_pbm in 'psycho_scan_bus' This is first step towards more readable warnings. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: link vmlinux.o before kallsyms passesSam Ravnborg2008-01-281-2/+4
| | | | | | | link vmlinux.o so we may report section mismatch bugs before we start with the real link - that may error out. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: introduce new option to enhance section mismatch analysisSam Ravnborg2008-01-283-2/+42
| | | | | | | | | | | Setting the option DEBUG_SECTION_MISMATCH will report additional section mismatch'es but this should in the end makes it possible to get rid of all of them. See help text in lib/Kconfig.debug for details. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* Use separate sections for __dev/__cpu/__mem code/dataSam Ravnborg2008-01-283-60/+159
| | | | | | | | | | | | | | | | | | | | | Introducing separate sections for __dev* (HOTPLUG), __cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG) allows us to do a much more reliable Section mismatch check in modpost. We are no longer dependent on the actual configuration of for example HOTPLUG. This has the effect that all users see much more Section mismatch warnings than before because they were almost all hidden when HOTPLUG was enabled. The advantage of this is that when building a piece of code then it is much more likely that the Section mismatch errors are spotted and the warnings will be felt less random of nature.

* all archs: consolidate init and exit sections in vmlinux.lds.hSam Ravnborg2008-01-2829-117/+140
| | | | | | | | | | | This patch consolidate all definitions of .init.text, .init.data and .exit.text, .exit.data section definitions in the generic vmlinux.lds.h. This is a preparational patch - alone it does not buy us much good. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: check section names consistently in modpostSam Ravnborg2008-01-281-86/+60
| | | | | | | Now that match() is introduced use it consistently so we can share the section name definitions. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: introduce blacklisting in modpostSam Ravnborg2008-01-281-177/+128
| | | | | | | | | | | | | | | | | | | | | | Change the logic in modpost so we identify all the bad combinations of sections that refer to other sections. Compared to the previous approach we are much less dependent on knowledge of what additional sections the tool chain uses and thus we can keep the false positives low. The implmentation is changed to use a table based lookup and we now check all combinations in first pass so we no longer need separate passes for init and exit sections. Tested that the same warnings are generated for an allyesconfig build without CONFIG_HOTPLUG.

* kbuild: code refactoring in modpostSam Ravnborg2008-01-281-105/+137
| | | | | | | | | | | Split a too long function up in smaller bits to make prgram logic easier to follow. A few related changes done due to parameter changes. No functional changes. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: try harder to find symbol names in modpostSam Ravnborg2008-01-282-2/+19
| | | | | | | | | | | | | | | | The relocation record sometimes contained an address which was not an exactly match for a symbol. Implment some simple logic such that if there is a symbol within 20 bytes of the address contained in the relocation record then print the name of this symbol. With this change modpost could find symbol names for the remaining .init.text symbols in my allyesconfig build for x86_64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: fix so modpost can now check any .o fileSam Ravnborg2008-01-281-1/+2

* kconfig: make kconfig MinGW friendlyLadislav Michl2008-01-283-66/+32
| | | | | | | | | | | | | | | | | | | | | | | Kconfig is powerfull tool. So powerfull that more and more software projects are using it for configuration. So instead of fixing some of them one by one, lets fix it in kernel and wait for sync. This work was originaly done for PTXdist - GPL licensed build system for userlands and cross-compilers, but it will not hurt kernel kconfig either. PTXdist menuconfig now works on Windows linked with PDCurses and compiled using MinGW - there is no termios and signals. * Do not include <sys/wait.h> and <signal.h> (comes from times when lxdialog was separate process) * Do not mess with termios directly and let curses tell screen size. Comment to commit c8dc68ad0fbd934e78e913b8a8d7b45945db4930 says check for screen size could be removed later, but because it didn't happen for more than year I left it here as well. * Save cursor position added by Sam Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
