| * scripts/kallsyms.c: fix potential segfaultXiaochen Wang2011-05-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Description: This bug hardly appears during real kernel compiling, because the vmlinux symbols table is huge. But we can still catch it under strict condition , as follows. $ echo "c101b97b T do_fork" | ./scripts/kallsyms --all-symbols #include <asm/types.h> ...... ...... .globl kallsyms_token_table ALGN kallsyms_token_table: Segmentation fault (core dumped) $ If symbols table is small, all entries in token_profit[0x10000] may decrease to 0 after several calls of compress_symbols() in optimize_result(). In that case, find_best_token() always return 0 and best_table[i] is set to "\0\0" and best_table_len[i] is set to 2. As a result, expand_symbol(best_table[0]="\0\0", best_table_len[0]=2, buf) in write_src() will run in infinite recursion until stack overflows, causing segfault. This patch checks the find_best_token() return value. If all entries in token_profit[0x10000] become 0 according to return value, it breaks the loop in optimize_result(). And expand_symbol() works well when best_table_len[i] is 0.

| * kbuild: Fix GNU make v3.80 compatibilityKevin Cernekee2011-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Documentation/Changes, the kernel should be buildable with GNU make 3.80+. Commit 88d7be031f9f975bb3f50a0b5ef3796a671e7edf (kbuild: Use a single clean rule for kernel and external modules) introduced the "$(or" construct, which requires make 3.81. This causes "make clean" to malfunction when it is used with external modules. Replace "$(or" with an equivalent "$(if" expression, to restore backward compatibility.

| * kbuild: Fix passing -Wno-* options to gcc 4.4+Michal Marek2011-05-033-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Starting with 4.4, gcc will happily accept -Wno-<anything> in the cc-option test and complain later when compiling a file that has some other warning. This rather unexpected behavior is intentional as per http://gcc.gnu.org/PR28322, so work around it by testing for support of the opposite option (without the no-). Introduce a new Makefile function cc-disable-warning that does this and update two uses of cc-option in the toplevel Makefile.

| * Fix handling of backlash character in LINUX_COMPILE_BY nameMarcin Nowakowski2011-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When using a domain login, `whoami` returns the login in user\domain format. This leads to either warnings on unrecognised escape sequences or escaped characters being generated for the user. This patch ensures that any backslash is escaped to a double-backslash to make sure the name is preserved correctly. This patch does not enforce escaping on the KBUILD_BUILD_USER variable, as this is something the user has control of and can escape if required.

| * kbuild: asm-generic supportSam Ravnborg2011-04-285-5/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an increasing amount of header files shared between individual architectures in asm-generic. To avoid a lot of dummy wrapper files that just include the corresponding file in asm-generic provide some basic support in kbuild for this. With the following patch an architecture can maintain a list of files in the file arch/$(ARCH)/include/asm/Kbuild To use a generic file just add: generic-y += <name-of-header-file.h> For each file listed kbuild will generate the necessary wrapper in arch/$(ARCH)/include/generated/asm. When installing userspace headers a wrapper is likewise created. The original inspiration for this came from the unicore32 patchset - although a different method is used. The patch includes several improvements from Arnd Bergmann. Michael Marek contributed Makefile.asm-generic.

| * kbuild: implement several W= levelsSam Ravnborg2011-04-282-29/+44

Divide the warning options in three groups: W=1 - warnings that may be relevant and does not occur too often W=2 - warnings that occur quite often but may still be relevant W=3 - the more obscure warnings, can most likely be ignored When building the whole kernel, those levels produce: W=1 - 4859 warnings W=2 - 1394 warnings W=3 - 86666 warnings respectively. Warnings have been counted with Geert's script at http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/linux-log-summary.pl Many warnings occur from .h files so fixing one file may have a nice effect on the total number of warnings. With these changes I am actually tempted to try W=1 now and then. Previously there was just too much noise. Borislav: - make the W= levels exclusive - move very noisy and making little sense for the kernel warnings to W=3 - drop -Woverlength-strings due to useless warning message - copy explanatory text for the different warning levels to 'make help' - recount warnings per level Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Borislav Petkov <bp@alien8.de> Cc: Dave Jones <davej@redhat.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

| * kbuild: move KALLSYMS_EXTRA_PASS from Kconfig to MakefileArtem Bityutskiy2011-04-152-17/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we have the CONFIG_KALLSYMS_EXTRA_PASS Kconfig switch, which users can enable or disable while configuring the kernel. This option is then used by 'make' to determine whether an extra kallsyms pass is needed or not. However, this approach is not nice and confusing, and this patch moves CONFIG_KALLSYMS_EXTRA_PASS from Kconfig to Makefile instead. The rationale is below. 1. CONFIG_KALLSYMS_EXTRA_PASS is really about the build time, not run-time. There is no real need for it to be in Kconfig. It is just an additional work-around which should be used only in rare cases, when someone breaks kallsyms, so Kbuild/Makefile is much better place for this option. 2. Grepping CONFIG_KALLSYMS_EXTRA_PASS shows that many defconfigs have it enabled, probably not because they try to work-around a kallsyms bug, but just because the Kconfig help text is confusing and does not really make it clear that this option should not be used unless except when kallsyms is broken. 3. And since many people have CONFIG_KALLSYMS_EXTRA_PASS enabled in their Kconfig, we do might fail to notice kallsyms bugs in time. E.g., many testers use "make allyesconfig" to test builds, which will enable CONFIG_KALLSYMS_EXTRA_PASS and kallsyms breakage will not be noticed. To address that, this patch: 1. Kills CONFIG_KALLSYMS_EXTRA_PASS 2. Changes Makefile so that people can use "make KALLSYMS_EXTRA_PASS=1" to enable the extra pass if needed. Additionally, they may define KALLSYMS_EXTRA_PASS as an environment variable. 3. By default KALLSYMS_EXTRA_PASS is disabled and if kallsyms has issues, "make" should print a warning and suggest using KALLSYMS_EXTRA_PASS Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> [mmarek: Removed make help text, is not necessary] Signed-off-by: Michal Marek <mmarek@suse.cz>

| | | | | | | | | | | | | | | | | | | | Dumb users like myself are not able to grasp from the existing KALLSYMS_ALL documentation that this option is not what they need. Improve the help message and make it clearer that KALLSYMS is enough in the majority of use cases, and KALLSYMS_ALL should really be used very rarely.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | None of the latest GPUs had this hooked up, this is necessary for correct operation in a lot of cases, however we should test this on a few GPUs in these families as we've had problems in this area before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This needs to be explicitly set on btc. It's set by default on evergreen/fusion, so it fine to just unconditionally enable it for all chips.
