Fix some PS3 repository.c build warnings when DEBUG is defined. Also change most pr_debug calls to pr_devel calls. Fixes warnings like these: format '%lx' expects type 'long unsigned int', but argument 7 has type 'u64' Signed-off-by: NGeoff Levand <geoff@infradead.org> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

For 64-bit FSL_BOOKE implementations, gigantic pages need to be reserved at boot time by the memblock code based on the command line. This adds the call that handles the reservation, and fixes some code comments. It also removes the previous pr_err when reserve_hugetlb_gpages is called on a system without hugetlb enabled - the way the code is structured, the call is unconditional and the resulting error message spurious and confusing.

Before hugetlb, at each level of the table, we test for !0 to determine if we have a valid table entry. With hugetlb, this compare becomes: < 0 is a normal entry 0 is an invalid entry > 0 is huge This works because the hugepage code pulls the top bit off the entry (which for non-huge entries always has the top bit set) as an indicator that we have a hugepage.

The original 32-bit hugetlb implementation used PPC64 vs PPC32 to determine which code path to take. However, the final hugetlb implementation for 64-bit FSL ended up shared with the FSL 32-bit code so the actual check needs to be FSL_BOOK3E vs everything else. This patch changes the include protections to reflect this. There are also a couple of related comment fixes.

This patch does 2 things: It corrects the code that determines the size to write into MAS1 for the PPC_MM_SLICES case (this originally came from David Gibson and I had incorrectly altered it), and it changes the methodolody used to calculate the size for !PPC_MM_SLICES to work for 64-bit as well as 32-bit.

There was an unconditional return of "1" in the original code from David Gibson, and I dropped it because it wasn't needed for FSL BOOKE 32-bit. However, not all systems (including 64-bit FSL BOOKE) do loading of the hpte from the fault handler asm and depend on this function returning 1, which causes a call to update_mmu_cache() that writes an entry into the tlb.

The Cell and PowerMac platforms use virtually identical cascaded-IRQ setup code, so just merge it into the core. Ideally this code would trigger automatically when an MPIC device-node specifies an "interrupts" property, perhaps even enabling MPIC_SECONDARY along the way. Unfortunately, Benjamin Herrenschmidt has had bad experiences in the past with the quality of Apple PowerMac device-trees, so to be safe we will only try to parse out an IRQ if the MPIC_SECONDARY flag is set by the caller.

Almost all PowerPC platforms use a standard "open-pic" device node so the mpic_alloc() function now accepts NULL for the device-node.

The MPIC code can already perform an automatic OF address translation step as part of mpic_alloc(), but several boards need to use that base address when they perform mpic_assign_isu(). The easiest solution is to save the computed physical address into the "struct mpic" for later use by the board code.

Instead of using the open-coded "reg" property lookup and address translation in mpic_alloc(), directly call of_address_to_resource(). This includes various workarounds for special cases which the naive of_address_translate() does not. Afterwards it is possible to remove the copiously copy-pasted calls to of_address_translate() from the 85xx/86xx/powermac platforms.
