2008-05-30[S390] disassembler: fix idte instruction format.Martin Schwidefsky

2008-05-30[S390] showmem: Only walk spanned pages.Heiko Carstens
Convert show_mem() so its nearly the same as on x86/powerpc. Gives us proper locking and we get also rid of the only use of max_mapnr. Also the number of pages was contained in an int which might not be sufficient not too far in the future.

2008-05-30[S390] Fix section mismatch warnings.Heiko Carstens
This fixes the last remaining section mismatch warnings in s390 architecture code. It reveals also a real bug introduced by... me with git commit 2069e978d5a6e7b45d58027e3de7f879b8c5e488 ("[S390] sparsemem vmemmap: initialize memmap.") Calling the generic vmemmap_alloc_block() function to get initialized memory is a nice idea, however that function is __meminit annotated and therefore the function might be gone if we try to call it later. This can happen if a DCSS segment gets added. So basically revert the patch and clear the memmap explicitly to fix the original bug.

git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6: [IA64] Workaround for RSE issue
2008-05-27[IA64] Workaround for RSE issueTony Luck
Problem: An application violating the architectural rules regarding operation dependencies and having specific Register Stack Engine (RSE) state at the time of the violation, may result in an illegal operation fault and invalid RSE state. Such faults may initiate a cascade of repeated illegal operation faults within OS interruption handlers. The specific behavior is OS dependent. Implication: An application causing an illegal operation fault with specific RSE state may result in a series of illegal operation faults and an eventual OS stack overflow condition. Workaround: OS interruption handlers that switch to kernel backing store implement a check for invalid RSE state to avoid the series of illegal operation faults. The core of the workaround is the RSE_WORKAROUND code sequence inserted into each invocation of the SAVE_MIN_WITH_COVER and SAVE_MIN_WITH_COVER_R19 macros. This sequence includes hard-coded constants that depend on the number of stacked physical registers being 96. The rest of this patch consists of code to disable this workaround should this not be the case (with the presumption that if a future Itanium processor increases the number of registers, it would also remove the need for this patch). Move the start of the RBS up to a mod32 boundary to avoid some corner cases. The dispatch_illegal_op_fault code outgrew the spot it was squatting in when built with this patch and CONFIG_VIRT_CPU_ACCOUNTING=y Move it out to the end of the ivt.

2008-05-23x86: distangle user disabled TSC from unstableThomas Gleixner
tsc_enabled is set to 0 from the command line switch "notsc" and from the mark_tsc_unstable code. Seperate those functionalities and replace tsc_enable with tsc_disable.

2008-05-23x86: fix setup of cyc2ns in tsc_64.cThomas Gleixner
When the TSC is calibrated against the PIT due to the nonavailability of PMTIMER/HPET or due to SMI interference then the setup of the per CPU cyc2ns variables is skipped. This is unlikely to happen but it would definitely render sched_clock() unusable. This was introduced with commit 53d517cdbaac704352b3d0c10fecb99e0b54572e x86: scale cyc_2_nsec according to CPU frequency Update the per CPU cyc2ns variables in all exit pathes of tsc_calibrate.

2008-05-23[POWERPC] mpic: Fix use of uninitialized variableStephen Rothwell
Compiling ppc64_defconfig with gcc 4.3 gives thes warnings: arch/powerpc/sysdev/mpic.c: In function 'mpic_irq_get_priority': arch/powerpc/sysdev/mpic.c:1351: warning: 'is_ipi' may be used uninitialized in this function arch/powerpc/sysdev/mpic.c: In function 'mpic_irq_set_priority': arch/powerpc/sysdev/mpic.c:1328: warning: 'is_ipi' may be used uninitialized in this function It turns out that in the cases where is_ipi is uninitialized, another variable (mpic) will be NULL and it is dereferenced. Protect against this by returning if mpic is NULL in mpic_irq_set_priority, and removing mpic_irq_get_priority completely as it has no in tree callers. This has the nice side effect of making the warning go away.
