2012-05-18x86, realmode: 16-bit real-mode code support for relocs toolH. Peter Anvin1-0/+2
A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree.

2012-05-17MCA: delete all remaining traces of microchannel bus support.Paul Gortmaker2-2/+2
Hardware with MCA bus is limited to 386 and 486 class machines that are now 20+ years old and typically with less than 32MB of memory. A quick search on the internet, and you see that even the MCA hobbyist/enthusiast community has lost interest in the early 2000 era and never really even moved ahead from the 2.4 kernels to the 2.6 series. This deletes anything remaining related to CONFIG_MCA from core kernel code and from the x86 architecture. There is no point in carrying this any further into the future. One complication to watch for is inadvertently scooping up stuff relating to machine check, since there is overlap in the TLA name space (e.g. arch/x86/boot/mca.c).

2012-05-07kbuild: all{no,yes,mod,def,rand}config only read files when instructed to.Eric W. Biederman1-1/+3
Prevent subtle surprises to both people working on the kconfig code and people using make allnoconfig allyesconfig allmoconfig and randconfig by only attempting to read a config file if KCONFIG_ALLCONFIG is set. Common sense suggests attempting to read the extra config files does not make sense unless requested. The documentation says the code won't attempt to read the extra config files unless requested. Current usage does not appear to include people depending on the code reading the config files without the variable being set So do the simple thing and stop reading config files when passed all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment variable is set.

Move the final link of vmlinux to a script to improve readability and maintainability of the code. The Makefile fragments used to link vmlinux has over the years seen far too many changes and the logic had become hard to follow. As the process by nature is serialized there was nothing gained including this in the Makefile. "um" has special link requirments - and the only way to handle this was to hard-code the linking of "um" in the script. This was better than trying to modularize it only for the benefit of "um" anyway.

2012-05-01HID: Allow bus wildcard matchingHenrik Rydberg1-1/+2

2012-05-01HID: Add device group to modaliasHenrik Rydberg1-0/+2
HID devices are only partially presented to userland. Hotplugged devices emit events containing a modalias based on the basic bus, vendor and product entities. However, in practise a hid device can depend on details such as a single usb interface or a particular item in a report descriptor. This patch adds a device group to the hid device id, and broadcasts it using uevent and the device modalias. The module alias generation is modified to match. As a consequence, a device with a non-zero group will be processed by the corresponding group driver instead of by the generic hid driver.

The BCJ filters were meant to be enabled already on these archs, but the xz_wrap.sh script was buggy. Enabling the filters should give smaller kernel images. xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect the architecture.

Commit f02e8a6596b7 ("module: Sort exported symbols") sorts symbols placing each of them in its own elf section. This sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux.o (which is not linked yet) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure. [ This above is a slightly corrected version of the explanation of the problem, copied from commit 62a2635610db ("modpost: Fix modpost's license checking V3").

2012-03-24ARM: 7333/2: jump label: detect %c support for ARMRabin Vincent1-1/+17
Some versions of ARM GCC which do support asm goto, do not support the %c specifier. Since we need the %c to support jump labels on ARM, detect that too in the asm goto detection script to avoid build errors with these versions. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48637 Acked-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-23checkpatch: check for quoted strings broken across linesJosh Triplett1-0/+15
checkpatch already makes an exception to the 80-column rule for quoted strings, and Documentation/CodingStyle recommends not splitting quoted strings across lines, because it breaks the ability to grep for the string. Rather than just permitting this, actively warn about quoted strings split across lines. Test case: void context(void) { struct { unsigned magic; const char *strdata; } foo[] = { { 42, "these strings" "do not produce warnings" }, { 256, "though perhaps" "they should" }, }; pr_err("this string" " should produce a warning\n"); pr_err("this multi-line string\n" "should not produce a warning\n"); asm ("this asm\n\t" "should not produce a warning"); } Results of checkpatch on that test case: WARNING: quoted string split across lines + " should produce a warning\n"); total: 0 errors, 1 warnings, 15 lines checked Signed-off-by: Josh Triplett <josh@joshtriplett.org> Acked-by: Joe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-03-23checkpatch: add --strict tests for braces, comments and castsJoe Perches1-8/+32
Add some more subjective --strict tests. Add a test for block comments that start with a blank line followed only by a line with just the comment block initiator. Prefer a blank line followed by /* comment... Add a test for unnecessary spaces after a cast. Add a test for symmetric uses of braces in if/else blocks. If one branch needs braces, then all branches should use braces.
