8b756d40a7 Update syscall.master to 4.10-rc6. Also fix comments, a typo,
and wrong numbering for a few unimplemented syscalls.

For 32-bit Linuxulator, socketcall() syscall was historically
the entry point for the sockets API. Starting in Linux 4.3, direct
syscalls are provided for the sockets API. Enable it.

The initial version of patch was provided by trasz@ and extended by me.

21b737495b Introduce __read_mostly and __exclusive_cache_line macros.
The intended use is to annotate frequently used globals which either rarely
change (and thus can be grouped in the same cacheline) or are an atomic counter
(which means it may benefit from being the only variable in the cacheline).

Linker script support is provided only for amd64. Architectures without it risk
having other variables put in, i.e. as if they were not annotated. This is
harmless from correctness point of view.

Right now size of the structure is 472 bytes on amd64, which is
already large and stack allocations are indesirable.  With the ino64
work, MNAMELEN is increased to 1024, which will make it impossible to have

This patch solves a problem where the kernel linker will incorrectly

to a panic when these functions are used.

6faefea03b linuxkpi: Fix PCI BAR lazy allocation support.
FreeBSD supports lazy allocation of PCI BAR, that is, when a device
driver's attach method is invoked, even if the device's PCI BAR
address wasn't initialized, the invocation of bus_alloc_resource_any()
(the call chain: pci_alloc_resource() -> pci_alloc_multi_resource() ->
pci_reserve_map() -> pci_write_bar()) would allocate a proper address
for the PCI BAR and write this 'lazy allocated' address into the PCI
BAR.

This model works fine for native FreeBSD device drivers, but _not_ for
device drivers shared with Linux (e.g. dev/mlx5/mlx5_core/mlx5_main.c
and ofed/drivers/net/mlx4/main.c.  Both of them use
pci_request_regions(), which doesn't work properly with the PCI BAR
lazy allocation, because pci_resource_type() -> _pci_get_rle() always
returns NULL, so pci_request_regions() doesn't have the opportunity to
invoke bus_alloc_resource_any().  We now use pci_find_bar() in
pci_resource_type(), which is able to locate all available PCI BARs
even if some of them will be lazy allocated.
