The checkbin target on PPC32 isn't quite right. First, one of the tests (to ensure that some instructions are known to gas) is never actually invoked because 'checkbin' doesn't know about stuff set in .config, so we always have the 'else' case run. This changes to always running the test and telling the user to upgrade to at least binutils 2.12.1. The next problem is that we were doing $(AS) -o /dev/null ... in both that test, as well as another. The problem here is that the checkbin target is run on the install targets, meaning that /dev/null will get unlinked when the test passes. To get around this we use .tmp_gas_check as the output file instead. Acked by Sam. Signed-off-by:

NFS takes some thought to switch to the new symlink scheme, because we can't rely on the pagecache lookup to find the symlink page when freeing it - the cache might have been invalidated in the meantime. So we hide the page information in the symlink data area itself, by stealing the last pointer in the page used for the cache. That way nfs_put_link() can just look up the page directly.

Massaged altroot handling to avoid on-stack struct nameidata instance (and got it faster, actually). We are in the middle of do_follow_link() recursion here, so the stack footprint is critical. Signed-off-by:

Both gcc and sparse will speed up tokenization by noticing when a header file is protected by the standard preprocessor #ifndef .. #endif exclusion. However, that requires that the headers actually _use_ that standard exclusion. Some did their own little broken dance.

Sigh... a) mixing of userland and kernel pointers is bad b) so's not checking result of kmalloc() c) so's not checking result of copy_from_user() d) use of do { .... break; ... break; ... } while(0); is *highly* unidiomatic. Do not confuse kernel with IOCCC, please. And if you have religious aversion to multiple return statements in a function, at least learn the reasons why it is frowned upon in many situations. Hint: they all apply to use of break in that manner. e) 0 instead of NULL Signed-off-by: -

This adds support for the new compiler options -mkernel-backchain, -mstack-size, -mstack-guard, -mwarn-dynamicstack and -mwarn-framesize. The option -mkernel-backchain enables the use of modified layout for the stack frames of kernel functions. This breaks the ABI, modules compiled with the option won't work on a kernel compiled with the option and vice versa. The positive effect of the option is a drastic reduction of kernel stack use. The trick is that the new frame layout allows to overlap the 96 (31 bit)/160 (64 bit) byte bias areas of the functions on the call chain. This lowers the minimal stack usage of a function from 96 bytes to 16 bytes (31 bit) and 160 bytes to 24 bytes (64 bit). The kernel stack use is decreased to a point where it is possible to use 4K (31 bit) / 8K (64 bit) stacks. The split into process stack and interrupt stack is already in place. The options -mstack-size and -mstack-guard are used to detect kernel stack overflows. The compiler adds code to the prolog of every function that causes an illegal operation if the kernel stack is about to overflow. The options -mwarn-dynamicstack and -mwarn-framesize cause the compiler to emit warnings if a function uses dynamic stack allocation or if the function frame size is bigger then a specified limit. To play safe all the new options are configurable. Signed-off-by:

This patch fixes a problem reported by David S. Miller <davem@redhat.com> "I just noticed that fb_{read,write}() uses copy_*_user() with the kernel buffer being the frame buffer. It needs to use the proper device address accessor functions." The patch will do an intermediate copy of the contents to a page-sized, kmalloc'ed buffer.
