We need to implement kvm_check_and_clear_guest_paused() on powerpc to
make these warnings go away

Title:
kernel bug seen
My guess is the card doesn't support 64bit DMA, it supports something
less than that. A quick hack in sound/pci/hda/hda_intel.c to disable
64bit DMA fixes it:
- if ((gcap & AZX_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64)))
+ if (0 && (gcap & AZX_GCAP_64OK) && !pci_set_dma_m
This is a multipath issue. The box has two cards with redundant paths to
each disk.
Multipath is meant to create /dev/mapper/mpath* devices, and the
installer should use them instead of the underlying /dev/sd* devices.

Talking to benh, the main issue in the PCIE hotplug driver.
Unfortunately that is not a module:
CONFIG_HOTPLUG_PCI_PCIE=y
Could we get that disabled in the ppc64le defconfig? We don't have any
hardware that needs it.

powerpc: Use unstripped VDSO image for more accurate profiling data
We are seeing a lot of hits in the VDSO that are not resolved by perf.
A while(1) gettimeofday() loop show
I see what is going on, but don't know how to fix it yet.
Gdb must be checking for program headers that are marked load or
segments that are marked allocate (not exactly sure what yet). The
.symtab and .strtab are not, because normally they are not loaded into
memory.
The problem is bfd_elf_get_e
Still trawling through gdb, but the issue appears to be in
bfd/elfcode.h, bfd_from_remote_memory:
shdr_end = i_ehdr.e_shoff + i_ehdr.e_shnum * i_ehdr.e_shentsize;
[17] .shstrtab STRTAB 001603 be 00
0 0 1
[18] .symtab SYMTAB 000
Of course it's the actual section headers at that offset. Now the
question is, should we fix bfd_from_remote_memory so it can read
sections after the section headers assuming they are in memory.

Public bug reported:
Binary package hint: gnome-color-manager
gcm-prefs (maverick) asks and tries to install shared-color-targets.
This fails because the package doesn't exist.
It looks like I can grab this via Pascal de Bruijn's Lucid ppa, but it
would be nice if it shipped in universe with gno
Sorry about that.
1 Start gcm-prefs.
2 Select a device that can be profiled, ie the "Create Profile for Device"
button isn't greyed out. (In my case a Canon EOS Rebel XTi)
3 Click "Create Profile for Device"
Looking at the source, src/gcm-calibrate.c gcm_calibrate_device():

Wasn't expecting miracles here, just thought I'd point it out so it
eventually gets fixed. Thanks for looking!
