This fixes /tmp usage in make-release script for security.
Also, create output directory if it does not exist.
This also adds a 'tarball' optin to specify output file name.

The kvm mmu synchronizes shadow ptes using the mmu lock, however the cpu
will happily ignore the lock when setting the accessed bit. This can cause
the accessed bit to be lost. Luckily this only results in incorrect page
selection for swap.
This patchset fixes the problem by atomically updating
__set_spte() will happily replace an spte with the accessed bit set with
one that has the accessed bit clear. Add a helper update_spte() which checks
for this condition and updates the page flag if needed.

Currently, in the window between the check for the accessed bit, and actually
dropping the spte, a vcpu can access the page through the spte and set the bit,
which will be ignored by the mmu.
Fix by using an exchange operation to atmoically fetch the spte and drop it.
