338b122b2b net/tcp/sendfile: fixed an issue with unackseq calculation. 
Wrong unackseq calculation locked conn->tx_unacked at non-zero values
even if all ACKs were received.
This issue is the same as it was with tcp_send_unbuffered.

2a22c0e32d risc-v/mpfs: OpenSBI: utilize an index2id table 
Hart index to hart id table is used to track unused and used harts. This
table is useful when configuring only some of the harts for OpenSBI use.
Mpfs will always have the hart0 unused, so mark it with -1.

c4b3672937 RISC-V MMU driver: fix region setting for L1/L2 page tables

33435e76da Changes to Sv39 MMU driver public header 
- Define RV_MMU_PT_LEVELS as the arch max
- Add way to find the PPN from a PTE
- Make utility function to create a satp register value, instead of
  combining this to mmu_enable
- Add function to read the current satp value
- Add function to write the satp register, also fix the fence instruction

926a19217e Add simple MMU driver for RISC-V (Sv39) 
Sv39 is the only mode supported for now. However, it should be trivial
to extend the driver to support the other modes (including Sv32) as well.

The driver is tested with mpfs only, but it should work with any riscv
implementation.

less redefinition conflicts. OpenSBI declares some of the

There is no such section. Instead, place the object mpfs_head.o at the start of
the text.

Put mpfs_head.o directly into the arch library; there is no need to define
it separately in HEAD_ASRC.

Add a new configuration for CONFIG_N_IRQ_STACKS, whcih defaults to
CONFIG_SMP_NCPUS or 1
- this allows configuring multiple IRQ stacks also in the case where SMP
  support is not needed
- this is specifically needed in mpfs target, where "bootloader" build boots
  only on one hart, but the startup code executes on all harts and handles SW IRQs

Also don't store/restore GP if RISCV_SAVE_GP is not defined. If the GP is not
stored in fork, it can't be restored for new tasks
