由 H. Peter Anvin 提交于
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 scripts/x86-relocs.c so it will be compiled before building the arch/x86 tree. Signed-off-by: NH.

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. That way it doesn't need to care about the subarchs (like i386 vs. x86_64) since the BCJ filters don't care either.

The symbol table on x86-64 starts to have entries that have names like: _GLOBAL__sub_I_65535_0___mod_x86cpu_device_table They are of type STT_FUNCTION and this one had a length of 18. This matched the device ID validation logic and it barfed because the length did not meet the device type's criteria. -------------------- FATAL: arch/x86/crypto/aesni-intel: sizeof(struct x86cpu_device_id)=16 is not a modulo of the size of section __mod_x86cpu_device_table=18. Fix definition of struct x86cpu_device_id in mod_devicetable.h -------------------- These are some kind of compiler tool internal stuff being emitted and not something we want to inspect in modpost's device ID table validation code. So skip the symbol if it is not of type STT_OBJECT. Signed-off-by: NDavid S. Miller <davem@davemloft.net> Acked-by: NSam Ravnborg <sam@ravnborg.org> Signed-off-by: NMichal Marek <mmarek@suse.cz>

This reverts commit 953742c8. Dumping two lines into autoconf.h for all existing Kconfig options results in a giant file (~16k lines) we have to process each time we compile something.

Commit f02e8a65 ("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 62a26356 ("modpost: Fix modpost's license checking V3"). That commit fixed the problem for module object files, but not for vmlinux.o. This patch fixes modpost for vmlinux.o. ] Signed-off-by: NFrank Rowand <frank.rowand@am.sony.com> Signed-off-by: NAlessio Igor Bogani <abogani@kernel.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

由 Roland Dreier 提交于
In some circumstances (eg when running a build in an emacs shell buffer), I get a spew of messages like grep: writing output: Broken pipe from setlocalversion, because the "read" subshell apparently exits as soon as it reads one line and gives EPIPE to grep. It's not clear to me why this way of writing the check was used instead of just using grep -q to suppress output, but unless there is some deep reason I don't know, this way looks cleaner to me anyway, and gets rid of the ugly message spew. (I double checked at http://pubs.opengroup.org/onlinepubs/009604499/utilities/grep.html and "grep -q" is specified in POSIX / SuS, so hopefully even people cross-compiling the kernel on some bizarre host OS can't complain about this change) Signed-off-by: NRoland Dreier <roland@purestorage.com> Signed-off-by: NMichal Marek <mmarek@suse.cz>

"echo -e" is a GNU extension. When cross-compiling the kernel on a BSD-like operating system (Mac OS X in my case), this doesn't work. One could install a GNU version of echo, put that in the $PATH before the system echo and use "/usr/bin/env echo", but the solution with printf is simpler. Since it is no disadvantage on Linux, I hope that gets accepted even if cross-compiling the Linux kernel on another Unix operating system is quite a rare use case.

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: NJosh Triplett <josh@joshtriplett.org> Acked-by: NJoe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
