If a scsi host driver specifies .cmd_len in it's scsi_host_template, a driver's
private command pool is needed. scsi_find_host_cmd_pool() will locate it, but
scsi_alloc_host_cmd_pool() isn't saving the pool address in the host template.
This will result in an access error whe
The x86 architecture offers via the PAT (Page Attribute Table) a way to
specify different caching modes in page table entries. The PAT MSR contains
8 entries each specifying one of 6 possible cache modes. A pte references one
of those entries via 3 bits: _PAGE_PAT, _PAGE_PWT and _PAGE_PCD.
The Lin
From: Juergen Gross
With the dynamical mapping between cache modes and pgprot values it is now
possible to use all cache modes via the Xen hypervisor PAT settings in a
pv domain.
All to be done is to read the PAT configuration MSR and set up the translation
tables accordingly.

Update the translation tables from cache mode to pgprot values according to
the PAT settings. This enables changing the cache attributes of a PAT index in
just one place without having to change at the users side.
With this change it is possible to use the same kernel with di
From: Juergen Gross
At the moment there are a lot of places that handle setting or getting
the page cache mode by treating the pgprot bits equal to the cache mode.
This is only true because there are a lot of assumptions about the setup
of the PAT MSR. Otherwise the cache type needs to get transl

bind_interdomain_evtchn_to_irq() is currently a private function. It is used
only by bind_interdomain_evtchn_to_irqhandler() to register an irq-handler for
an event channel.
By making it public it is possible to use e.g. threaded interrupts with
interdomain event channels.
