* [SSB]: add Sonics Silicon Backplane bus supportMichael Buesch2007-10-101-0/+19
| | | | | | | | | | | | | | SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically.

* kconfig: oldconfig shall not set symbols if it does not need toRoman Zippel2007-09-011-9/+12
| | | | | | | | | | | | | | | Avoid setting the value if the symbol doesn't need to be changed or can't be changed. Later choices may change the dependencies and thus the possible input range. make oldconfig from a 2.6.22 .config with CONFIG_HOTPLUG_CPU not set was in some configurations setting CONFIG_HOTPLUG_CPU=y without asking, even when there was no actual requirement for CONFIG_HOTPLUG_CPU. This was triggered by SUSPEND_SMP that does a select HOTPLUG_CPU.

* kbuild: fix modpost warnings for xtensaSam Ravnborg2007-07-251-6/+24
| | | | | | | | | | | | | | | | | | | The Xtensa architecture places literal pools in sections separate from the instructions. The corresponsing text sections, therefore, reference the .literal section, and we have to suppress those warnings. The naming convention defines the name for a literal section as .SECTION.literal, unless .SECTION is .text. In that case the name is only .literal. Using strncmp() instead of strcmp() to compare the from-section with .SECTION.init.refok in pattern 0 should not cause any regressions for other architectures. We also need to suppress warnings for two informational sections (.xt.lit and .xt.prop) used by the Xtensa architecture.

* kbuild: be more foregiving on init section namingSam Ravnborg2007-07-251-26/+10
| | | | | | | | | | | | | In the whitelist function of modpost now use the same check to identify init_section as in other places of modpost. This has the effect that we now recognize sections named .init.text.19 as init sections and we no longer warn when we see these. At the same time make surrounding code readable by dropping use of temporary flags. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| | | | | | | | | | | | | | | | | | | | | | | | The only in-kernel user of "memmem" is scripts/kallsyms.c and it only uses it to find tokens that are 2 bytes in size.

| * kconfig: reset generated values only if Kconfig and .config agree.Roman Zippel2007-07-171-11/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally generated values (Kconfig entries without a prompt) are cleared as they are regenerated anyway and so they appear as new should they become visible and defaults work as expected (once a value is set defaults aren't used anymore). The detection whether a value is generated or not is only based on its visibility status, which can quickly change for a lot of symbols by just removing a single line from .config or adding a dependency to Kconfig as you noticed. The patch now suppresses this logic when .config and Kconfig aren't in sync and .config needs to be updated, so that you can remove now a random value from .config and oldconfig won't reask for many other values.

Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only.

|/ | | | | | | | | | | | | | | | | | | | | | | | KSYM_NAME_LEN is peculiar in that it does not include the space for the trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating buffer. This is nonsense and error-prone. Moreover, when the caller forgets that it's very likely to subtly bite back by corrupting the stack because the last position of the buffer is always cleared to zero. This patch increments KSYM_NAME_LEN by one and updates code accordingly. * off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro is fixed. * Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together, MODULE_NAME_LEN was treated as if it didn't include space for the trailing '\0'.

* update checkpatch.pl to version 0.07Andy Whitcroft2007-07-161-196/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version brings a number of new checks, fixes for flase positives, plus a clarification of the output to better guide use. Of note: - checks for documentation for new __setup calls - clearer reporting where braces and parenthesis are involved - reports for closing brace and semi-colon spacing - reports on unwanted externs This patch includes an update to the documentation on checkpatch.pl itself to clarify when it should be used and to indicate that it is not intended as the final arbitor of style. Full changelog: Andy Whitcroft (19): Version: 0.07 ensure we do not apply control brace checks to preprocesor directives add {u,s}{8,16,32,64} to the type matcher accept lack of spacing after the semicolons in for (;;) report new externs in .c files fix up typedef exclusion for function prototypes else trailing statements check need to account for \ at end of line add enums to the type matcher add missing check descriptions suppress double reporting of ** spacing report on do{ spacing issues include an example of the brace/parenthesis in output check for spacing after closing braces prevent double reports on pointer spacing issues handle blank continuation lines on macros classify all reports error, warning, or check revamp hanging { checks and apply in context no spaces after the last ; in a for is ok check __setup has a corresponding addition to documentation David Woodhouse (1): limit character set used in patches and descriptions to UTF-8 Signed-off-by: Andy Whitcroft <apw@shadowen.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: "Randy.Dunlap" <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* x86_64: fix headers_installDavid Woodhouse2007-07-061-1/+1
| | | | | | | | | | | | | | | | | | A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of files all of which are using the same #ifdef guard, "__ASM_STUB_" with no postfix. So the second and later asm files #included in the same C file (often through standard headers like ioctl.h) yields no symbols. Strangeness with the Ubuntu 'tell me if I support something that's not explcitly mentioned in POSIX, and I'll strip it out' shell, I believe. We don't need the 'export' but we do need a semicolon at the end of the FNAME line: Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Rob Landley <rob@landley.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARMDavid Woodhouse2007-06-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Not all the world is an i386. Many architectures need 64-bit arguments to be aligned in suitable pairs of registers, and the original sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an argument register for padding after the first integer. Since we don't normally have more than 6 arguments for system calls, that left no room for the final argument on some architectures. Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which all fits nicely. In fact, ARM already had that, but called it sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement the needed compatibility routine. And stop the missing syscall check from bitching about the absence of sys_sync_file_range() if we've implemented sys_sync_file_range2() instead. Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.
