[PATCH 1/4] drm/nouveau: add reg_debug module parameter
The various register access wrappers in nouveau_hw.h are so noisy when
drm.debug > 0, that some of them can overflow the kernel message buffer.
Add nouveau.ko parameter 'reg_debug', a bitmask that enables each of the
wrapper debug messages individually. By default, nothing is printed.

[LLVMdev] Infinite loop in llc on ARMv7 (LLVM HEAD from June 17)
Hello,
it looks like I do have infinite loop in llc on linux/armv7 platform
somewhere in llvm::SmallVectorImpl. Two backtraces obtained with 10
seconds delay are:
0x0099be14 in llvm::SmallVectorTemplateCommon<llvm::SDNode*>::setEnd
(this=0x7ee90b38, P=0x5c06988)
at /export/home/karel/vcs/llvm-head/include/llvm/ADT/SmallVector.h:103

Aligning ragged text columns
Can anyone please suggest how I can print:
a <- matrix(c(
"Heading 1", "This is some info\nabout heading 1",
"Heading 2", "This is some info\nabout heading 2",
), byrow=T, nrow=2)
to look like:
Heading 1 This is some info
about heading 1
Heading 2 This is some info
about heading 2
