2014-08-08scripts/checkstack.pl: automatically handle 32-bit and 64-bit mode for ARCH=x86Konstantin Khlebnikov
This patch adds support for ARCH=x86 into checkstack. Commit ffee0de411fd ("x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT") had merged ARCH=i386 and ARCH=x86_64 into one ARCH=x86. checkstack.pl searches patterns of machine instructions which are usually used for allocating stack frames. checkstalk.pl needs either i386 or x86_64, x86 isn't enough: $ make checkstack objdump -d vmlinux $(find . -name '*.ko') | \ perl linux/scripts/checkstack.pl x86 wrong or unknown architecture "x86" Signed-off-by: Konstantin Khlebnikov <koct9i@gmail.com> Cc: David Woodhouse <dwmw2@infradead.org> Cc: "H.

Cleanup checkstack script: * Turn on strict checking * Fix resulting error message because the declaration syntax was incorrect. * Remove incorrect and misleading use of prototype - prototype not required for this type of sort function because $a and $b are being used in this contex - if prototype was being used it should be for both arguments * Use closure for sort function Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Arjan van de Ven <arjan@infradead.org> Cc: Cong Wang <amwang@redhat.com> Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

2008-07-25find dynamic stack allocations in checkstack.plEric Sandeen
Currently, checkstack.pl only looks for fixed subtractions from the stack pointer. However, things like this: void function(int size) { char stackbuster[size << 2]; ... are certainly worth pointing out, I think. This could perhaps be done more cleanly, and the following patch only adds "dynamic" REs for x86 and x86_64, but it works: 0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax) 0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax) 0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax) 0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax) ...

I have been prime author and maintainer of block2mtd from day one, but neither MAINTAINERS nor the module source makes this fact clear. And while I'm at it, update my email addresses tree-wide, as the old address currently bounces and change my name to "joern" as unicode will likely continue to cause trouble until the end of this century.

2006-06-25[PATCH] checkstack: print module namesRandy Dunlap
Finding "init_module" high stack usage problems is challenging when there are over 1600 "init_module" functions in the kernel tree, so make checkstack.pl print out the filename where the stack usage occurs. This is useful for code built as loadable modules. For built-in code, it just prints the kernel image file name, like "vmlinux". Examples: (before patch:) 0x0000000d callback: 1928 0xffffffff81678c09 huft_build: 1560 0x0018 init_module: 1512 (after patch:) 0x0000000d callback [divacapi]: 1928 0xffffffff81678c09 huft_build [vmlinux]: 1560 0x0018 init_module [hdaps]: 1512 Also change one if-series to use elsif to cut down on unneeded tests.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
