Currently we downshift to MSI/Legacy if we don't get enough vectors for
cpu_count RSS rings plus cpu_count TX completion rings. This patch
allows running MSIX with the vector count that the platform provides.

Currently we have three types of RX rings.
1) Default ring - services rx_ring for broadcast/multicast, handles
firmware events, and errors.
2) TX completion ring - handles only outbound completions.
3) RSS ring - handles only inbound completions.
This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring. This makes better use of MSIX vectors since
they are a limited resource on some platforms.

bonding: Have bond_check_dev_link examine netif_running
Some network devices do not call netif_carrier_off when they
are set administratively down. Have the bonding link check function
also inspect the netif_running state. Ignore netif_running if the
bond_check_dev_link function is called with "reporting" set, as in that
case it's inspecting the capabilities of the non-netif_carrier device
driver.

-tip testing found that this patch breaks the build on x86 if
CONFIG_KALLSYMS is disabled:
kernel/module.c: In function ‘load_module’:
kernel/module.c:2367: error: ‘struct module’ has no member named ‘sect_attrs’
distcc[8269] ERROR: compile kernel/module.c on ph/32 failed

Commit 1b364bf misses the fact that section attributes are only
built and dealt with if kallsyms is enabled. The patch below fixes
this.
( note, technically speaking this should depend on CONFIG_SYSFS as
well but this patch is correct too and keeps the #ifdef less
intrusive - in the KALLSYMS && !SYSFS case the code is a NOP. )

Extend SFI to access standard ACPI tables.
(eg. the PCI MCFG) using sfi_acpi_table_parse().
Note that this is _not_ a hybrid ACPI + SFI mode.
The platform boots in either ACPI mode or SFI mode.
SFI runs only with acpi_disabled=1, which can be set
at build-time via CONFIG_ACPI=n, or at boot time by
the failure to find ACPI platform support.
So this extension simply allows SFI-platforms to
re-use existing standard table formats that happen to
be defined to live in ACPI envelopes.

linux/acpi.h is the top level header for interfacing
with the ACPI sub-system, so acpi_disabled should be
up there instead of down in asm/acpi.h -- particularly
since asm/acpi.h doesn't exist for all architectures.
Same story for acpi_table_parse(), which is a top-level
API to Linux/ACPI.
This is necessary for building some code that
used to always depend on CONFIG_ACPI=y, but will soon
also need to build with CONFIG_ACPI=n.

Some IO-APIC routines are ACPI specific now, but need to
be exposed when CONFIG_ACPI=n for the benefit of SFI.
Remove #ifdef ACPI around these routines:
io_apic_get_unique_id(int ioapic, int apic_id);
io_apic_get_version(int ioapic);
io_apic_get_redir_entries(int ioapic);
Move these routines from ACPI-specific boot.c to io_apic.c:
uniq_ioapic_id(u8 id)
mp_find_ioapic()
mp_find_ioapic_pin()
mp_register_ioapic()
Also, since uniq_ioapic_id() is now no longer static,
re-name it to io_apic_unique_id() for consistency
with the other public io_apic routines.
For simplicity, do not #ifdef the resulting code ACPI || SFI,
thought that could be done in the future if it is important
to optimize the !ACPI !SFI IO-APIC x86 kernel for size.
