sp_tlb_flush_pte_usiii() and switchtoctx_us()/switchtoctx_usiii() and
implement the latter while i'm here. it works ... sometimes i think,
but also sometimes panics/hangs.
- fix a comment in sparc64_ipi_flush_pte_usiii()
- Lower fault routines don't care the vm_anon array found in upper lookup.
Don't pass the pointer down.
- The flag "shadowed" is known when we lookup upper layer. Don't need to
keep in the fault context struct.
- sparc64_ipi_flush_pte() becomes sparc64_ipi_flush_pte_us() and
sparc64_ipi_flush_pte_usiii()
- add some commented out code to disable interrupts and raise the traplevel
in sparc64_ipi_flush_pte_usiii()
- cache_flush_phys() was missing a little of code in the cheetah case
the original values. Pointed out by rmind@, thanks.
In the lower fault case, if (*pgo_get)() can return ERESTART and we should
re-fault for that remains a question. The original code just returned the
error, so keep that behaviour for now. In case (*pgo_get)() really returns
ERESTART, pass EIO to tell the uvm_fault caller that (*pgo_get)() failed.
(As far as I grep callers don't check if the return value is ERESTART or not.
So assuming (*pgo_get)() never returns ERESTART should be a safe bet.)
in a bunch more cases
- make sparc64_ipi_halt_thiscpu() and sparc64_ipi_pause_thiscpu() return void,
their callers never checked anyway.
- remove prototypes for sparc64_ipi_flush_ctx() and sparc64_ipi_flush_all(),
there are no such functions
by a set (selected via a passed callback predicate) of sensors.
This provides an easy way to query the current temperature of a thermal
zone, for example, from within the kernel - assuming the caller knows
the topology.
* -H, --xidhwaddr uses the last 4 bytes of the hardware address as
the DHCP xid
* -J, --broadcast tells the DHCP server to broadcast replies
* no longer warn about InfiniBand being an unsupported family
* infinite lease times are valid when reading old leases
* discard address correctly if lease is invalid
