+Status 2005-10-28 :
+-------------------
+ - Merged to 2.6.15
+
+Todo:
+-----
+
+ - Review and eliminate all warnings for io accesses with an eye to
+ turning on ioremap
+ - 2005-02-04 (Carlos) Review the gettimeofday
+ implementation, possibly use a light-weight-syscall and
+ rely on cr16 and cpu speed for more accurate timing?
+ This requires adding some backwards compatibility code in
+ userspace since the LWS might not be available on the
+ booted kernel. Detecting LWS is a problem.
+ - PREEMPT support
+ - CPU hotplug: we cannot bring up cpus after init, and we don't know if we can
+ shutdown cpus
+ - task_struct/thread_info split -- task_struct should not be visible in
+ entry.S, we need to move some items into thread_info -- this includes
+ pt_regs and maybe some of the flags (ptrace, etc)
+ - flush_tlb_kernel_range is horribly inefficient. this has been merged
+ with the userspace tlb flush, but it has a magic constant that needs
+ tuning
+ - Superdome support
+ - our PDC early debug console hacks need to be cleaned up somehow
+ - CPU IRQ affinity (willy)
+ - Allow more than BITS_PER_LONG cpu interrupts to be allocated (willy)
+ - 64-bit userspace (Leandro)
+ - syscall signal return path needs work, we don't loop on signal
+ delivery like other archs.
+ = 2005-02-04 (Carlos) This entry should be more specific,
+ we recently fixed do_signal such that it always
+ loops forcing the signal. If this was the bug then it was
+ fixed.
+
+
+Drivers
+-------
+
+ - write Lasi floppy driver
+ - write Suckyio floppy driver
+ - write spifi driver (rbrad)
+ - modify ncr53c8xx driver for Outfield (735 & 755)
+ - write GSC FDDI driver
+ - write Timi ASIC (74x) support
+ - EISA DMA support
+
+
+Started and in progress:
+------------------------
+ - 2004-08-16 (Carlos)
+ 64-bit binutils needs to be fixed to get multiple stub
+ section support.
+ - port hil_kbd.c to new input layer
+ - port hil_ptr.c to new input layer
+
+
+CONFIG options without help:
+-----------------------------
+ - REVIEW THESE ENTRIES!
+
+ _USB_OHCI_HCD (add parisc info?)
+ _HP_SDC_RTC
+ _HIL_MLC
+ _HIL_KBD (to improve)
+ _HIL_PTR (to improve)
+
+
+Review all the todo entries below!
+----------------------------------
+
+ - the fix for do_fork needs checking
+ - ns87415 dma doesn't work reliably on suckyio-systems
+ - (ab)use kmap/kunmap on 64-bit to eliminate flush_dcache calls.
+ - cp_new_stat32 for sys_parisc32.c is inefficient; maybe it's better
+ to fill in a tmp stat32 and just do copy_to_user in one go at the end?
+ - investigate not putting in extable entries for put_kernel_asm; will
+ probably reduce kernel size
+ - fix HIL problem: ksoftirqd/0 eats 56% cpu (kernel 2.4 & kernel 2.6)
+ - NPTL kernel support (CLONE_*TID flags need to be correctly handled by
+ sys_clone() and friends)

-**
-** The Linux port of the FreeBSD ncr driver has been achieved in
-** november 1995 by:
-**
-** Gerard Roudier <groudier@free.fr>
-**
-** Being given that this driver originates from the FreeBSD version, and
-** in order to keep synergy on both, any suggested enhancements and corrections
-** received on Linux are automatically a potential candidate for the FreeBSD
-** version.
-**
-** The original driver has been written for 386bsd and FreeBSD by
-** Wolfgang Stanglmeier <wolf@cologne.de>
-** Stefan Esser <se@mi.Uni-Koeln.de>
