x86, realmode: 16-bit real-mode code support for relocs tool

2012-05-19T02:49:40Z

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. [ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ] Signed-off-by: H.

Pull build system failure fix from Michal Marek: "This fixes build failure with newer gcc that adds some internal symbols that end in "__mod_*_device_table", but are not actually the tables themselves." * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: Fix modpost failures in fedora 17

xz: Enable BCJ filters on SPARC and 32-bit x86

2012-04-18T20:13:18Z

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. Signed-off-by: Lasse Collin Acked-by: Jan Beulich Acked-by: H.

Fix modpost failures in fedora 17

2012-04-18T19:42:07Z

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: David S. Miller Acked-by: Sam Ravnborg Signed-off-by: Michal Marek

kconfig: delete last traces of __enabled_ from autoconf.h

2012-04-13T01:35:58Z

We've now fixed IS_ENABLED() and friends to not require any special "__enabled_" prefixed versions of the normal Kconfig options, so delete the last traces of them being generated. Signed-off-by: Paul Gortmaker Signed-off-by: Linus Torvalds

Revert "kconfig: fix __enabled_ macros definition for invisible and un-selected symbols"

2012-04-13T01:35:58Z

This reverts commit 953742c8fe8ac45be453fee959d7be40cd89f920. 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. We've weaned IS_ENABLED() and similar off of requiring the __enabled_ definitions so now we can revert the change which caused all the extra lines.

modpost: Fix modpost license checking of vmlinux.o

2012-04-10T03:52:56Z

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"). That commit fixed the problem for module object files, but not for vmlinux.o. This patch fixes modpost for vmlinux.o. ] Signed-off-by: Frank Rowand Signed-off-by: Alessio Igor Bogani Signed-off-by: Linus Torvalds

Merge branch 'akpm' (Andrew's patch-bomb)

Merge batch of fixes from Andrew Morton: "The simple_open() cleanup was held back while I wanted for laggards to merge things. I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes. So I need to go back and re-review those patchs and their (lengthy) discussion." * emailed from Andrew Morton : (16 patches) memcg swap: use mem_cgroup_uncharge_swap fix backlight: add driver for DA9052/53 PMIC v1 C6X: use set_current_blocked() and block_sigmask() MAINTAINERS: add entry for sparse checker MAINTAINERS: fix REMOTEPROC F: typo alpha: use set_current_blocked() and block_sigmask() simple_open: automatically convert to simple_open() scripts/coccinelle/api/simple_open.cocci: semantic patch for simple_open() libfs: add simple_open() hugetlbfs: remove unregister_filesystem() when initializing module drivers/rtc/rtc-88pm860x.c: fix rtc irq enable callback fs/xattr.c:setxattr(): improve handling of allocation failures fs/xattr.c:listxattr(): fall back to vmalloc() if kmalloc() failed fs/xattr.c: suppress page allocation failure warnings from sys_listxattr() sysrq: use SEND_SIG_FORCED instead of force_sig() proc: fix mount -t proc -o AAA
