certain devices
When a user requests Promiscuous mode on SkyHawk-R devices,
the FW enables Desparate Promiscuous mode.
Due to this, we need to explicitly enable Multicast Promiscuous mode
so that Multicast packets are received as well.
This patch fixes that.

The tx priority pause count is available with the driver.
But we were not showing it.
This change should fix it and display it in ethtool stats.

Only BE devices provide 16-bit counter for rx_drops_no_fragment.
All other devices provide a 32-bit counter for this stat.
Use the 32-bit value where available.

This is to fix a merge problem with mach-highbank/hotplug.c, which git
silently resolves, but wrongly. This commit contains the correct

The Tilera hypervisor shipped in releases up through MDE 4.1 launches
the client operating system (i.e. Linux) at privilege level 1 (PL1).
Starting with MDE 4.2, as part of the work to enable KVM, the
Tilera hypervisor launches Linux at PL2 instead.
This commit makes the KERNEL_PL option default to 2 for tilegx, while
still saying at 1 for tilepro, which doesn't have an updated hypervisor.
It also explains how and when you might want to choose another value.
In addition, we change a small buglet in the on-chip Ethernet driver,
where we were failing to use the KERNEL_PL constant in an API call.
To make the transition cleaner, this change also provides the updated
hv_init() API for the new hypervisor that supports announcing Linux's
compiled-in PL, so the hypervisor can generate a suitable error in the
case of a mismatched hypervisor and Linux binary.

If attempting to abort requests due to a fail fail timeout
or error handling while the link is down, we cannot send
an abort out on the fabric. We can, however, send a cancel
to the VIOS. This fixes ibmvfc to send a cancel in this
case to prevent error handling from failing and/or
escalating.

Consistently check errors using the usual method used in the kernel
for much of its history. For instance:
int gpmc_cs_set_timings(int cs, const struct gpmc_timings *t)
{
int div;
div = gpmc_calc_divider(t->sync_clk);
if (div < 0)
return div;
static int gpmc_set_async_mode(int cs, struct gpmc_timings *t)
{
...
return gpmc_cs_set_timings(cs, t);
.....
ret = gpmc_set_async_mode(gpmc_onenand_data->cs, &t);
if (IS_ERR_VALUE(ret))
return ret;
So, gpmc_cs_set_timings() thinks any negative return value is an error,
but where we check that in higher levels, only a limited range are
errors...
There is only _one_ use of IS_ERR_VALUE() in arch/arm which is really
appropriate, and that is in arch/arm/include/asm/syscall.h:
static inline long syscall_get_error(struct task_struct *task,
struct pt_regs *regs)
{
unsigned long error = regs->ARM_r0;
return IS_ERR_VALUE(error) ? error : 0;
}
because this function really does have to differentiate between error
return values and addresses which look like negative numbers (eg, from
mmap()).
So, here's a patch to remove them from OMAP, except for the above.
