Pull fixup for trivial branch from Jiri Kosina:
"Unfortunately I made a mistake when merging into for-linus branch, and
omitted one pre-requisity patch for a few other patches (which have
been Acked by the appropriate maintainers) in the series. Mea culpa
maxima, sorry for that."
The trivial branch added %pSR usage before actually teaching vsnprintf()
about the 'R' part of %pSR. The 'R' causes the symbol translation to do
a "__builtin_extract_return_addr()" before symbol lookup.
That said, on most architectures __builtin_extract_return_addr() isn't
likely to do anything special, so it probably is not normally
noticeable.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial:
vsprintf: Add extension %pSR - print_symbol replacement
|
|
print_symbol takes a long and converts it to a function
name and offset. %pS does something similar, but doesn't
translate the address via __builtin_extract_return_addr.
%pSR does the translation.
This will enable replacing multiple calls like
printk(...);
printk_symbol(addr);
printk("\n");
with a single non-interleavable in dmesg
printk("... %pSR\n", (void *)addr);
Update documentation too.

Add the %pa format specifier for printing a phys_addr_t type and its
derivative types (such as resource_size_t), since the physical address
size on some platforms can vary based on build options, regardless of
the native integer type.

There are many places in the kernel where the drivers print small buffers
as a hex string. This patch adds a support of the variable width buffer
to print it as a hex string with a delimiter. The idea came from Pavel
Roskin here: http://www.digipedia.pl/usenet/thread/18835/17449/
Sample output of
pr_info("buf[%d:%d] %*phC\n", from, len, len, &buf[from]);
could be look like this:
[ 0.726130] buf[51:8] e8:16:b6:ef:e3:74:45:6e
[ 0.750736] buf[59:15] 31:81:b8:3f:35:49:06:ae:df:32:06:05:4a:af:55
[ 0.757602] buf[17:5] ac:16:d5:2c:ef

Bluetooth uses mostly LE byte order which is reversed for visual
interpretation. Currently in Bluetooth in use unsafe batostr function.
This is a slightly modified version of Joe's patch (sent Sat, Dec 4,
