In commit 7d172bfe ("Alchemy: Add UART PM methods") I introduced
platform PM methods which call a function of the 8250 driver;
this patch works around link failures when the kernel is built
without 8250 support.

The nvram_get function was never in the mainline kernel, it only existed in
an external OpenWrt patch. Use nvram_getenv function, which is in mainline
and use an include instead of an extra function declaration. et0macaddr
contains the mac address in text from like 00:11:22:33:44:55. We have to
parse it before adding it into macaddr.
nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h through
the MIPS git tree and will be available soon. It will not build now without
nvram_parse_macaddr, but it hasn't before either.

Fill the sprom with all available values from the nvram. Most of these
new values are needed for the b43 or b43legacy driver.

The config options read out here are not stored in CFE but only in NVRAM on

Consider the following test case:
write_c0_compare(read_c0_count());
Even if the counter doesn't increment during execution, this might not
generate an interrupt until the counter wraps around. The CPU may
perform the comparison each time CP0 COUNT increments, not when CP0
COMPARE is written.
If mips_next_event() is called with a very small delta, and CP0 COUNT
increments during the calculation of "cnt += delta", it is possible
that CP0 COMPARE will be written with the current value of CP0 COUNT.
If this is detected, the function should return -ETIME, to indicate
that the interrupt might not have actually gotten scheduled.

partial_fixup is used in noreorder block.
Separating two consecutive loads can save one cycle on processors with
GPR intrelock and can fix load-use on processors that need a load delay slot.
Also do so for fwd_fixup.
[Ralf: Only R2000/R3000 class processors are lacking the the load-user
interlock and even some of those got it retrofitted. With R2000/R3000
being fairly uncommon these days the impact of this bug should be minor.]

We were unconditionally sending SIGBUS with an empty siginfo on FP
emulator faults. This differs from what happens when real floating
point hardware would get a fault.
For most faults we need to send SIGSEGV with the faulting address
filled in in the struct siginfo.

TNETD7200 run their CPU clock faster than the default CPU clock we assume.
In order to have the correct loops per jiffies settings, initialize clocks right
before setting mips_hpt_frequency. As a side effect, we can no longer use
msleep in clocks.c which requires other parts of the kernel to be initialized,
so replace these with mdelay.

The return value of the vmalloc() call in arch/mips/kernel/vpe.c::vpe_open()
is not checked, so we potentially store a null pointer in v->pbuffer. Add
a check for a null return and then return -ENOMEM in that case.
[Ralf: The check added by Jesper's original patch is where it logically
should be. Adding it eleminated the need for the checks in a few other
places, so I removed them. There still is a zillion of other things that
need to be fixed in this file / API.]

The high bits of current->personality carry settings that we don't want to
clobber on each exec. Only clobber them if the lower bits that indicate
either PER_LINUX or PER_LINUX32 are invalid.
The clobbering prevents us from using useful bits like ADDR_NO_RANDOMIZE.

We never needed that (->regs[2] is overwritten on return from syscall paths
with return value of syscall, so storing it there early made no sense) and
with new restart logics since d27240bf7e61d2656de18e158ec910a902030847 it
has become really bad - we lose the original syscall number before the
place where we decide that we might need a syscall restart.
Note that for child we do need the assignment to regs[2] - it won't go
through the normal return from syscall path.

The install_special_mapping routine (used, for example, to setup the
vdso) skips the security check before insert_vm_struct, allowing a local
attacker to bypass the mmap_min_addr security restriction by limiting
the available pages for special mappings.
bprm_mm_init() also skips the check, and although I don't think this can
be used to bypass any restrictions, I don't see any reason not to have
the security check.

Cache ownership must be acquired by reading/writing data from the
cache line to make cache operation have the desired effect on the
SMP MPCore CPU. However, the ownership is never acquired in the
v6_dma_inv_range function when cleaning the first line and
flushing the last one, in case the address is not aligned
to D_CACHE_LINE_SIZE boundary.
Fix this by reading/writing data if needed, before performing
cache operations.
While at it, fix v6_dma_flush_range to prevent RWFO outside
the buffer.

Because the nwfpe support is unlikely to be used on new platforms
and requires CONFIG_OABI_COMPAT, which is not generally used with
ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2
kernel.
At present, nwfpe contains assembly code which isn't Thumb-2
compatible, and for now it doesn't appear useful to port this
code.
All ARMv7-A/R platforms necessarily have VFPv3 hardware floating-
point natively, making emulation unnecessary.

This makes sense, because Thumb-2 code can't execute on plain
ARMv6 processors.
This will avoid accidentally configuring a broken kernel where the
config otherwise would allow multiple architecture versions to
coexist in the same kernel.
Not adding !CPU_V5 etc., because the chance of anyone trying to
put v5 and v7 in the same kernel is low, and I'm not aware of
any mach which can do this. These could be added later if it
matters.
Note that the rules may need to be refined if support for the
ARM1156J(F)-S processor is later added to the kernel, since this
processor supports the rare ARMv6T2 extensions, which add support
for Thumb-2 and a few other ARMv7 features.

I am Jiandong Zheng working on BCMRING in Broadcom Canada Ltd. I am
replacing Leo Chen (leochen@broadcom.com) as "ARM/BCMRING ARM
ARCHITECTURE" and "ARM/BCMRING MTD NAND DRIVER" maintainer from
Broadcom as he is no longer the maintainer of these components.
