When 32-bit MIPS huge page support is enabled, we halve the number of
pointers a PTE page holds, making its last half go to waste.
Correspondingly, we should halve the number of kmap entries, as we just
initialized only a single pte table for that in pagetable_init().

1.Add a new TCU channel as the percpu timer of core1, this is to
prepare for the subsequent SMP support. The newly added channel
will not adversely affect the current single-core state.
2.Adjust the position of TCU node to make it consistent with the
order in jz4780.dtsi file.

Clang's integrated assembler only accepts these instructions when the

The cause of the problem is as follows:
1. when cat /sys/devices/system/memory/memory0/valid_zones,
test_pages_in_a_zone() will be called.
2. test_pages_in_a_zone() finds the zone according to stat_pfn = 0.
The smallest pfn of the numa node in the mips architecture is 128,
and the page corresponding to the previous 0~127 pfn is not
initialized (page->flags is 0xFFFFFFFF)
3. The nid and zonenum obtained using page_zone(pfn_to_page(0)) are out
of bounds in the corresponding array,
&NODE_DATA(page_to_nid(page))->node_zones[page_zonenum(page)],
access to the out-of-bounds zone member variables appear abnormal,
resulting in Oops.
Therefore, it is necessary to keep the page between 0 and the minimum
pfn to prevent Oops from appearing.

This fixes Page Table accounting bug.
MIPS is the ONLY arch just defining __HAVE_ARCH_PMD_ALLOC_ONE alone.
Since commit b2b29d6d011944 (mm: account PMD tables like PTE tables),
"pmd_free" in asm-generic with PMD table accounting and "pmd_alloc_one"
in MIPS without PMD table accounting causes PageTable accounting number
negative, which read by global_zone_page_state(), always returns 0.

The clock driving the XBurst CPUs in Ingenic SoCs is integer divided
from the main PLL. As such, it is possible to control the frequency of
the CPU, either by changing the divider, or by changing the rate of the
main PLL.
The XBurst CPUs also lack the CP0 timer; the TCU, a separate piece of
hardware in the SoC, provides this functionality.

I am not sure why this is required, but if this is not enabled, reading
from a buffer in which data has been DMA'd may read incorrect values.
This used to happen for instance in mmc_app_send_scr()

CAVIUM_OCTEON_SOC configuration selects HOLES_IN_ZONE option to cope with
memory crashes that were happening in 2011.
This option effectively aliases pfn_valid_within() to pfn_valid() when
enabled and hardwires it to 1 when disabled. The check for
pfn_valid_within() is only relevant in case the memory map may have holes
or undefined struct page instances inside MAX_ORDER chunks.
Since 2011 memory management initialization in general and memory map
initialization particularly became much more robust so the check for
pfn_valid_within() is not required on Octeon even despite its, hmm, unusual
memory setup.
Remove the selection of HOLES_IN_ZONE by CAVIUM_OCTEON_SOC and drop the
HOLES_IN_ZONE configuration option entirely as Octeon was the only MIPS
platform to use it.

buckets array size.

Pull RISC-V fixes from Palmer Dabbelt:
- A fix to avoid over-allocating the kernel's mapping on !MMU systems,
which could lead to up to 2MiB of lost memory
- The SiFive address extension errata only manifest on rv64, they are
now disabled on rv32 where they are unnecessary
- A pair of late-landing cleanups
