6c6dc56c1e CRIS v32: Add support for ETRAX FS and ARTPEC-3 for arch-v32/hwregs/eth_defs.h
- A couple of fields have changed name:
reg_eth_rw_ga_lo.table -> tbl
reg_eth_rw_ga_hi.table -> tbl
reg_eth_rw_gen_ctrl.flow_ctrl_dis -> flow_ctrl

- Add some new register fields.
reg_eth_rw_gen_ctrl.gtxclk_out
reg_eth_rw_gen_ctrl.phyrst_n
reg_eth_rw_tr_ctrl.carrier_ext

- max_size in reg_eth_rw_rec_ctrl had the wrong size.

- Registers reg_eth_rw_mgm_ctrl and reg_eth_r_stat was reworked completely.

6e16d89bcd Sanitize the type of struct user.u_ar0
struct user.u_ar0 is defined to contain a pointer offset on all
architectures in which it is defined (all architectures which define an
a.out format except SPARC.) However, it has a pointer type in the headers,
which is pointless -- <asm/user.h> is not exported to userspace, and it
just makes the code messy.

Redefine the field as "unsigned long" (which is the same size as a pointer
on all Linux architectures) and change the setting code to user offsetof()
instead of hand-coded arithmetic.

5e5419734c add mm argument to pte/pmd/pud/pgd_free
(with Martin Schwidefsky <schwidefsky@de.ibm.com>)

The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument.  The free functions do not get the mm_struct argument.  This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.

b0e86f0a3b CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common defines
- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD.
  The reservation up to page size of memory after init data was previously
  not done if BLK_DEV_INITRD was undefined.
  This caused a kernel oops when init memory pages were freed after startup,
  data placed in the same page as the last init memory would also be freed
  and reused, with disastrous results.

- Use macros for initcalls and .text sections.

- Replace hardcoded page size constant with PAGE_SIZE define.

- Change include/asm-cris/page.h to use the _AC macro to instead
  of testing __ASSEMBLY__.

d8e5219f9f CRISv10 improve and bugfix fasttimer
Improve and bugfix CRIS v10 fast timers.

- irq_handler_t now only takes two arguments.
- Keep interrupts disabled as long as we have a reference to the
  fasttimer list and only enable them while doing the callback.
  del_fast_timer may be called from other interrupt context.
- Fix bug where debug code could return without calling local_irq_restore.
- Use jiffies instead of usec (change from struct timeval to fasttime_t).
- Don't initialize static variables to zero.
- Remove obsolete #ifndef DECLARE_WAITQUEUE code.
- fast_timer_init should be __initcall.
- Change status/debug variables to unsigned.
- Remove CVS log and CVS id.

7b275523ab cris build fixes: corrected and improved NMI and IRQ handling
Corrects compile errors and the following:

- Remove oldset parameter from do_signal and do_notify_resume.

- Modified to fit new consolidated IRQ handling code.

- Reverse check order between external nmi and watchdog nmi to avoid false
  watchdog oops in case of a glitch on the nmi pin.

- Return from an pin-generated NMI the same way as for other interrupts.

- Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
  low-level asm interrupt handlers.  Fixed in the multiple interrupt
  handler also.

- Add space for thread local storage in thread_info struct.

- Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
  independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
  rtc and pci.

bafef0ae9d cris build fixes: update eth_v10.c ethernet driver
New (updated) version of ethernet driver for cris v10.

- First steps to simplify and make the MII code more similar
  between the etrax100 and etraxfs ports.

- Start the transmit queue before enabling tx interrupts
  to avoid race with the first frame.

- Flip the comparition statement to stick to physical addresses
  to avoid phys_to_virt mapping a potential null pointer.
  This was not an error but the change simplifies debugging
  of address-space mappings.

- Made myPrevRxDesc local to e100_rx since it was only used there.
  Fixed out of memory handling in e100_rx.  If dev_alloc_skb() fails
  persistently the system is hosed anyway but at least it won't
  loop in an interrupt handler.

- Correct some code formatting issues.

- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
  and SET_ETH_AUTONEG used in new cris v10 ethernet driver.
