kernel_text_address returns true even for modules which is not wanted
in text_poke. Use core_kernel_text instead.
This is a regression introduced in e587cadd8f47e202a30712e2906a65a0606d5865
which caused occasionaly crashes after suspend/resume.

OSF/1 brk(2) was broken by following one-liner in sys_brk()
(commit 4cc6028d4040f95cdb590a87db478b42b8be0508):
- if (brk < mm->end_code)
+ if (brk < mm->start_brk)
goto out;
The problem is that osf_set_program_attributes()
does update mm->end_code, but not mm->start_brk,
which still contains inappropriate value left from
binary loader, so brk() always fails.

Legacy IDE resources were never properly allocated on most
alpha platforms, so IDE expectedly stopped working after
commit 10f000a2fd805e8ccfe988e8615545467bb7f7df (generic
pci_enable_resources).
Always allocate "fixed" PCI resources before doing anything else;
remove Cypress IDE quirk, as it's a generic problem which is
handled in common PCI probe code.

The recent irq cleanups for arch/arm/mach-integrator/time.c and
drivers/char/mwave/tp3780i.c changed the request_irq() dev_id
parameter, but neglected to change the matching free_irq() parameter,
thus creating a bug upon irq de-registration.
Given that the impetus for the changes is not yet accepted upstream,
it is best to revert the irq cleanups.
Mostly. A comment is added to time.c to reduce future confusion,
of type that led to my time.c cleanup in the first place.

This sets us up for several simplifications and facilities:
1) The magic cookie lets us identify trap frames more
accurately in stack backtraces.
2) The trap type lets us simplify all of the "are we in
a syscall" state management and checks.
3) We can now see if a task off the cpu is sleeping in
a system call or not. In fact, we can see what
trap it is sleeping in whatever the type. The utrace
guys will use this.
Based upon some discussions with Roland McGrath.

While testing with CONFIG_VIRT_CPU_ACCOUNTING=y, I found that
I occasionally get very huge system time in some threads.
So I dug the issue and finally noticed that it was caused
because of an interrupt which interrupt in the following window:
> [arch/ia64/kernel/entry.S: (!CONFIG_PREEMPT && CONFIG_VIRT_CPU_ACCOUNTING)]
>
> ENTRY(ia64_leave_syscall)
> :
> (pUStk) rsm psr.i
> cmp.eq pLvSys,p0=r0,r0 // pLvSys=1: leave from syscall
> (pUStk) cmp.eq.unc p6,p0=r0,r0 // p6 <- pUStk
> .work_processed_syscall:
> adds r2=PT(LOADRS)+16,r12
> (pUStk) mov.m r22=ar.itc // fetch time at leave
> adds r18=TI_FLAGS+IA64_TASK_SIZE,r13
> ;;
> <<< window: from here >>>
> (p6) ld4 r31=[r18] // load current_thread_info()->flags
> ld8 r19=[r2],PT(B6)-PT(LOADRS)
> adds r3=PT(AR_BSPSTORE)+16,r12
> ;;
> mov r16=ar.bsp
> ld8 r18=[r2],PT(R9)-PT(B6)
> (p6) and r15=TIF_WORK_MASK,r31 // any work other than TIF_SYSCALL_TRACE?
> ;;
> ld8 r23=[r3],PT(R11)-PT(AR_BSPSTORE)
> (p6) cmp4.ne.unc p6,p0=r15, r0 // any special work pending?
> (p6) br.cond.spnt .work_pending_syscall
> ;;
> ld8 r9=[r2],PT(CR_IPSR)-PT(R9)
> ld8 r11=[r3],PT(CR_IIP)-PT(R11)
> (pNonSys) break 0 // bug check: we shouldn't be here if pNonSys is TRUE!
> ;;
> invala

> rsm psr.i | psr.ic // turn off interrupts and interruption collection
If pUStk is true, it means we are going to return user mode, hence we fetch
ar.itc to get time at leave from system.
It seems that it is not possible to interrupt the window if pUStk is true,
because interrupts are disabled early. And also disabling interrupt makes
sense because it is safe for referring current_thread_info()->flags.
However interrupting the window while pUStk is true was possible.
The route was:
ia64_trace_syscall
-> .work_pending_syscall_end
-> .work_processed_syscall
Only in case entering the window from this route, interrupts are enabled
during in the window even if pUStk is true. I suppose interrupts must be
disabled here anyway if pUStk is true.
I'm not sure but afraid that what kind of bad effect were there, other
than crazy system time which I found.
FYI, there was a commit 6f6d75825dc49b082906b84537b4df28293c2977 that
points out a bug at same point(exit of ia64_trace_syscall) in 2006.
It can be said that there was an another bug.
