Yes, I'm just using in kernel space: qemu has its own endian related helpers.
So if you allow us to place this macro in asm-generic/bitops/* it will help us.
No problem at all then. Thanks for the explanation.

Partition hibernation will use some of the same code as is
currently used for Live Partition Migration. This function
further abstracts this code such that code outside of rtas.c
can utilize it. It also changes the error field in the suspend

Hi Ben, we ran into an issue where it looks like we're not
properly ignoring a pci device with a non-good status property
when we walk the device tree and create our device nodes.
However, the EEH init code does look for the property and
disables EEH on these devices. This leaves us in an
If we take an EEH early enough, we oops:

On large machines we are running out of room below 256MB. In some cases we
only need to ensure the allocation is in the first segment, which may be

emergency stacks.
