Remove stale ide.h "configuration options":
* INITIAL_MULT_COUNT - always defined to 0
* SUPPORT_SLOW_DATA_PORTS - unused
* OK_TO_RESET_CONTROLLER - always defined to 1
* DISABLE_IRQ_NOSYNC - always defined to 0
Leave SUPPORT_VLB_SYNC (defined to 0 for CRIS and FRV, otherwise to 1)
for now but disallow overriding it by .There should be no functionality changes caused by this patch.

The old NO_IRQ define some platforms had was long ago declared obsolete
and wrong. FRV should therefore not be re-introducing this, especially as
IRQs are usually unsigned in the kernel. The "no IRQ" case is defined to be
zero and Linus made this rather clear at the time.arch/frv shows no dependancy on this but it might show up driver fixes
needing doing I guessSigned-off-by: Alan Cox

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.Signed-off-by: Jens Axboe

Add a Kconfig entry which will toggle some sanity checks on the sg

Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
NULL when passed such an entry.It's thus important that sg table users use the proper accessors to get
and set the page member.Signed-off-by: Jens Axboe

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.GCC can be made to warn about usage of long long types with ISO C90

then it doesn't cause warnings, namely by:#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;

frv is the last user in the tree of that dubious hook, and it's my
understanding that it's not even needed. It's only called by memory.c
free_pgd_range() which is always called within an mmu_gather, and
tlb_flush() on frv will do a flush_tlb_mm(), which from my reading of the
code, seems to do what flush_tlb_ptables() does, which is to clear the
cached PGE.Signed-off-by: Benjamin Herrenschmidt

Miscellaneous fixes to bring FRV up to date:
(1) Copy the new syscall numbers from i386 to asm-frv/unistd.h and fill out
the syscall table in entry.S too.(2) Mark __frv_uart0 and __frv_uart1 __pminitdata rather than __initdata so
that determine_clocks() can access them when CONFIG_PM=y.(3) Make arch/frv/mm/elf-fdpic.c include asm/mman.h so that MAP_FIXED is

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
I agree (with Andi Kleen) this typeof is not needed and more error
prone. All the original atomic.h code that uses cmpxchg (which includes
the atomic_add_unless) uses defines instead of inline functions,
probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
Digging into the FRV architecture shows me that it is also affected by
such a circular dependency. Here is the diff applying this against the
rest of my atomic.h patches.It applies over the atomic.h standardization patches.

This patch moves the die notifier handling to common code. Previous
various architectures had exactly the same code for it. Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at. avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.[akpm@linux-foundation.org: build fix]

Remove the Kconfig selection of semaphore debugging from the ALPHA and FRV
Kconfig files, and centralize it in lib/Kconfig.debug.There doesn't seem to be much point in letting individual architectures
independently define the same Kconfig option when it can just as easily be
