printk: help pr_debug and pr_devel to optimize out arguments

2016-02-13T10:34:10Z

commit fe22cd9b7c980b8b948ec85f034a8668c57ec867 upstream. Currently, pr_debug and pr_devel will not elide function call arguments appearing in calls to the no_printk for these macros. This is because all side effects must be honored before proceeding to the 0-value assignment in no_printk. The behavior is contrary to documentation found in the CodingStyle and the header file where these functions are declared. This patch corrects that behavior by shunting out the call to no_printk completely. The format string is still checked by gcc for correctness, but no code seems to be emitted in common cases.

treewide: use printf not attribute__((format(printf,...)))

2011-11-01T00:30:54Z

Standardize the style for compiler based printf format verification. Standardized the location of __printf too. Done via script and a little typing. $ grep -rPl --include=*.[ch] -w "__attribute__" * | \ grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \ xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*$\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*$\s*\)\s*\)/__printf($1, $2)/g ; print; }' [akpm@linux-foundation.org: revert arch bits] Signed-off-by: Joe Perches Cc: "Kirill A.

printk: allocate kernel log buffer earlier

2011-05-25T15:39:48Z

On larger systems, because of the numerous ACPI, Bootmem and EFI messages, the static log buffer overflows before the larger one specified by the log_buf_len param is allocated. Minimize the overflow by allocating the new log buffer as soon as possible. On kernels without memblock, a later call to setup_log_buf from kernel/init.c is the fallback.

include/linux/printk.h: move console functions and variables together

2011-01-13T16:03:09Z

There are many uses of printk_once(KERN_, so add pr__once macros to avoid printk_once(KERN_ pr_fmt(fmt). Add an #ifdef CONFIG_PRINTK for print_hex_dump and static inline void functions for the #else cases to reduce embedded code size. Neaten and organize the rest of the code.
