This patch adds an config switch to determine if we need to build some workaround helper files. The staging driver octeon-ethernet references some symbols which are only built when PCI is enabled. The new config switch enables these symbols in bothe cases.

flush_icache_range() is given virtual addresses to describe the region. It deals with these by attempting to translate them through the current set of page tables. This is fine for userspace memory and vmalloc()'d areas as they are governed by page tables. However, since the regions above 0x80000000 aren't translated through the page tables by the MMU, the kernel doesn't bother to set up page tables for them (see paging_init()). This means flush_icache_range() as it stands cannot be used to flush regions of the VM area between 0x80000000 and 0x9fffffff where the kernel resides if the data cache is operating in WriteBack mode. To fix this, make flush_icache_range() first check for addresses in the upper half of VM space and deal with them appropriately, before dealing with any range in the page table mapped area. Ordinarily, this is not a problem, but it has the capacity to make kprobes and kgdb malfunction. It should not affect gdbstub, signal frame setup or module loading as gdb has its own flush functions, and the others take place in the page table mapped area only.

Commit c52c2ddc ("alpha: switch osf_sigprocmask() to use of sigprocmask()") had several problems. The more obvious compile issues got fixed in commit 0f44fbd2 ("alpha: fix compile problem in arch/alpha/kernel/signal.c"), but it also caused a regression. Since _BLOCKABLE is already the set of signals that can be blocked, the code should do "newmask & _BLOCKABLE" rather than inverting _BLOCKABLE before masking.

The PL310 on the ct-ca9x4 tile for the Versatile Express does not need to add additional latency when accessing its cache RAMs. Unfortunately, the boot monitor sets this up for an 8-cycle delay on reads and writes, resulting in greatly reduced memory performance when the L2 cache is enabled. This patch sets the L2 RAM latencies to the correct value of 1 cycle on the ct-ca9x4 tile before enabling the L2 cache.

While debugging bit_spin_lock() hang, it was tracked down to gcc-4.4 misoptimization of non-inlined constant_test_bit() due to non-volatile addr when 'const volatile unsigned long *addr' cast to 'unsigned long *' with subsequent unconditional jump to pause (and not to the test) leading to hang. Compiling with gcc-4.3 or disabling CONFIG_OPTIMIZE_INLINING yields inlined constant_test_bit() and correct jump, thus working around the kernel bug. Other arches than asm-x86 may implement this slightly differently; 2.6.29 mitigates the misoptimization by changing the function prototype (commit c4295fbb) but probably fixing the issue itself is better.

We want interrupts disabled on all paths leading to RESTORE_ALL; otherwise, we are risking an IRQ coming between the updates of alpha_mv->hae_cache and *alpha_mv->hae_register and set_hae() within the IRQ getting badly confused. RESTORE_ALL used to play with disabling IRQ itself, but that got removed back in 2002, without making sure we had them disabled on all paths. It's cheaper to make sure we have them disabled than to revert to original variant... Remove the detritus left from that commit back in 2002; we used to need a reload of $0 and $1 since swpipl would change those, but doing that had become pointless when we stopped doing swpipl in there...

Currently we map 1 MB section while setting up SRAM on OMAPs Regardless of the actual memory. The physical OCM RAM available on OMAP SOCs is in order of KBs. This patch maps only available sram and cleans up some un-necessary cpu_is_xxx checks. Mapping un-available or non-accessible(secure) memory on the newer ARM processor is dangerous. Because ARM CPUs can now speculatively prefetch, we should avoid mapping any no-existing or secure memory.

This patch populates the L1 entries for MT_MEMORY and MT_MEMORY_NONCACHED types so that at boot-up, we can map memories outside system memory at page level granularity Previously the mapping was limiting to section level, which creates unnecessary additional mapping for which physical memory may not present. On the newer ARM with speculation, this is dangerous and can result in untraceable aborts.

This "bpt_code" instruction was killed off in our development line a while ago (the actual definition of bpt_code that is used is in kernel/traps.c) but I didn't push it for 2.6.36 because it seemed harmless and I didn't want to try to push more than absolutely necessary. However, we recently fixed a bug in our gcc that had been causing "-gdwarf2" not to be passed to the assembler, and passing this flag causes an erroneous assembler failure in the presence of code in a data section, sometimes. While we'd like to track down the bug in the assembler, we'd also like to make sure 2.6.36 builds with the current toolchain, so I'm removing this dead code as well.
