2006-12-12[MIPS] paging_init(): use highend_pfn/highstart_pfnFranck Bui-Huu
This patch makes paging_init() use highend_pfn/highstart_pfn globals. It removes the need of 'high' local which was needed only by HIGHMEM config. More important perhaps, it fixes a bug when HIGHMEM is set but there's actually no physical highmem (highend_pfn = 0) Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-12-12[MIPS] Discard .exit.text and .exit.data at runtime.Ralf Baechle
While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve things it didn't resolve all the problems. So bite the bullet and discard .exit.text and .exit.data at runtime. Which of course sucks because it bloats binaries with code that will never ever be used but it's the only thing that will work reliable as demonstrated by the function sd_major() in drivers/scsi/sd.c. Gcc may compile sd_major() using a jump table which it will put into .rodata. If it also inlines sd_major's function body into exit_sd() which gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld to discard exit_sd's code at link time. However sd_major happens to contain a switch statement which gcc will compile using a jump table in .rodata on the architectures I checked. So, when ld later discards .exit.text only the jump table in .rodata with its stale references to the discard .exit.text will be left which any no antique ld will honor with a link error.

2006-12-12sh: Fix get_wchan().Paul Mundt
Some time ago the schedule frame size changed and we failed to reflect this in get_wchan() at the time.

2006-12-12sh: BUG() handling through trapa vector.Paul Mundt
Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right. This also makes it trivial to wire up a DIE_BUG for the atomic die chain, which we couldn't really do before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2006-12-11[POWERPC] Generic BUG for powerpcJeremy Fitzhardinge
This makes powerpc use the generic BUG machinery. The biggest reports the function name, since it is redundant with kallsyms, and not needed in general. There is an overall reduction of code, since module_32/64 duplicated several functions. Unfortunately there's no way to tell gcc that BUG won't return, so the BUG macro includes a goto loop. This will generate a real jmp instruction, which is never used.

2006-12-11[POWERPC] Fix irq routing on some 32-bit PowerMacsBenjamin Herrenschmidt
The changes to use pci_read_irq_line() broke interrupt parsing on some 32-bit powermacs (oops). The reason is a bit obscure. The code to parse interrupts happens earlier now, during pcibios_fixup() as the PCI bus is being probed. However, the current implementation pci_device_to_OF_node() for 32-bit powerpc relies, on machines like PowerMac which renumber PCI buses, on a table called pci_OF_bus_map containing a map of bus numbers between the kernel and the firmware which is setup only later. Thus, it fails to match the device node. In addition, some of Apple internal PCI devices lack a proper PCI_INTERRUPT_PIN, thus preventing the fallback mapping code to work. This patch fixes it by making pci_device_to_OF_node() 32-bit implementation use a different algorithm that works without using the pci_OF_bus_map thing (which I intend to deprecate anyway). It's a bit slower but that function isn't called in any hot path hopefully. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2006-12-11[POWERPC] Support ibm,dynamic-reconfiguration-memory nodesPaul Mackerras
For PAPR partitions with large amounts of memory, the firmware has an alternative, more compact representation for the information about the memory in the partition and its NUMA associativity information. This adds the code to the kernel to parse this alternative representation. The other part of this patch is telling the firmware that we can handle the alternative representation. There is however a subtlety here, because the firmware will invoke a reboot if the memory representation we request is different from the representation that firmware is currently using. This is because firmware can't change the representation on the fly. Further, some firmware versions used on POWER5+ machines have a bug where this reboot leaves the machine with an altered value of load-base, which will prevent any kernel booting until it is reset to the normal value (0x4000). Because of this bug, we do NOT set fake_elf.rpanote.new_mem_def = 1, and thus we do not request the new representation on POWER5+ and earlier machines. We do request the new representation on POWER6, which uses the ibm,client-architecture-support call. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-12-10[PATCH] fdtable: Make fdarray and fdsets equal in sizeVadim Lobanov
Currently, each fdtable supports three dynamically-sized arrays of data: the fdarray and two fdsets. The code allows the number of fds supported by the fdarray (fdtable->max_fds) to differ from the number of fds supported by each of the fdsets (fdtable->max_fdset). In practice, it is wasteful for these two sizes to differ: whenever we hit a limit on the smaller-capacity structure, we will reallocate the entire fdtable and all the dynamic arrays within it, so any delta in the memory used by the larger-capacity structure will never be touched at all. Rather than hogging this excess, we shouldn't even allocate it in the first place, and keep the capacities of the fdarray and the fdsets equal. This patch removes fdtable->max_fdset. As an added bonus, most of the supporting code becomes simpler.
