I am not fully up to speed on NV/pmem stuff, but isn't that exactly what
the DAX mode is supposed to allow you to do? If so, isn't sharing a
mapped file on a DAX filesystem on top of pmem equivalent to what
you're proposing?

I have queued this in the tile tree as a tile-specific device, but
if someone would prefer to pick it up for a tty or tty/hvc tree,
that's fine too; just let me know.

The code accidentally used cpu_isset() previously in one place
(though properly node_isset() elsewhere).

Occasionally we report bugs for driver code that doesn't use the
get_unaligned_xxx() macros and friends, and our fixes are generally taken
upstream.

Hi Andrew,
Please drop patch 7/7 from -mm tree and keep other 6 patches.
arch_add_memory() in tile is different from others: no nid parameter.
Patch 7/7 will block compiling.
I cc this mail to Chris Metcalf and hope he can look at this issue.

The first version used an __ARCH_WANT_GENERIC_COMPAT_IPC define that
was set by tile, and presumably would be set by all
(https://patchwork.kernel.org/patch/843892/), which uses a simple
hypervisor read/write API to access the portion of the SPI ROM used to hold
the boot stream for a TILE processor.

That may be a mistake unless your console is genuinely only capable of
polled input.
The console is in fact
= hvc_alloc(0, 0, hvc_tile_get_put_ops, 128);
+ return IS_ERR(s) ? PTR_ERR(s) : 0;
}

I made the same change in hvsi.c since I happened to notice it was
