Dynamic debug recently added support for netdev_printk. It uses
__netdev_printk() to support this functionality. However, when CONFIG_NET
is not set, we get the following error:lib/built-in.o: In function `__dynamic_netdev_dbg':
(.text+0x9fda): undefined reference to `__netdev_printk'Fix this by making the call to netdev_printk() contingent upon CONFIG_NET.
We could have fixed this by defining netdev_printk() to a 'no-op' in the
!CONFIG_NET case. However, this is not consistent with how the networking
layer uses netdev_printk. For example, CONFIG_NET is not set,
netdev_printk() does not have a 'no-op' definition defined.Signed-off-by: Jason Baron

We were using KERN_CONT to combine messages with their prefix. However,
KERN_CONT is not smp safe, in the sense that it can interleave messages.
This interleaving can result in printks coming out at the wrong loglevel.
With the high frequency of printks that dynamic debug can produce this is
not desirable.So make dynamic_emit_prefix() fill a char buf[64] instead of doing a
printk directly. If we enable printing out of function, module, line, or
pid info, they are placed in this 64 byte buffer. In my testing 64 bytes
was enough size to fulfill all requests. Even if it's not, we can match
up the printk itself to see where it's from, so to me this is no big deal.[akpm@linux-foundation.org: convert dangerous macro to C]

To support >32-bit physical addresses for UIO_MEM_PHYS type we need to
extend the width of 'addr' in struct uio_mem. Numerous platforms like
embedded PPC, ARM, and X86 have support for systems with larger physical
address than logical.Since 'addr' may contain a physical, logical, or virtual address the
easiest solution is to just change the type to 'phys_addr_t' which
should always be greater than or equal to the sizeof(void *) such that
it can properly hold any of the address types.For physical address we can support up to a 44-bit physical address on a
typical 32-bit system as we utilize remap_pfn_range() for the mapping of
the memory region and pfn's are represnted by shifting the address by
the page size (typically 4k).Signed-off-by: Kai Jiang

"sysfs: use rb-tree for inode number lookup" added a new printk which
causes a new compile warning on s390 (and few other architectures):fs/sysfs/dir.c: In function 'sysfs_link_sibling':

When DEBUG_DRIVER is activated, be verbose and explicitly state when a
devicedriver match was rejected by the probe-function of the driver.
Now all code-paths report what is currently happening which helps
debugging, because you don't have to remember that no printout means
the match is rejected (and then you still don't know if it was because
of ENODEV or ENXIO).Signed-off-by: Wolfram Sang

The check to ensure that pages of recently added memory sections are correctly
marked as reserved before trying to online the memory is broken. The request
to online the memory fails with the following:kernel: section number XXX page number 256 not reserved, was it already online?
This updates the page reservation checking to check the pages of each memory
section of the memory block being onlined individually.Signed-off-by: Nathan Fontenot
