2006-02-24[PATCH] powerpc: Only calculate htab_size in one place for kexecMichael Ellerman3-8/+6
For kexec we need to know the size of the MMU hash table. Currently we calculate the size once in the htab code, and then twice more in the kexec code, once using htab_hash_mask and once using ppc64_pft_size. On some machines the ppc64_pft_size calculation is broken because ppc64_pft_size is not set. So we need to fix the second calculation, but better still we should just calculate the size once and use it everywhere else. Tested on Power5 LPAR, Power4 non-LPAR and Power3.

2006-02-22[ARM] 3325/2: GPIO function to control multi-drive (open collector) capabilityAndrew Victor3-1/+21
Patch from Andrew Victor This patch adds the at91_set_multi_drive() function to enable/disable the multi-drive (open collector) pin capability on the AT91RM9200 processor. This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200 board as it will not allow the board reset line to be pulled low if the pullup is not driven as an open collector output as the boards are wired to the USB connector on both the DK/EK.

Patch from Catalin Marinas The initial code did not configure the inbound memory windows for direct master access to the SDRAM. This patch creates a 1:1 mapping between the Versatile/PB PCI memory windows and its SDRAM.

2006-02-22Revert mount/umount uevent removalGreg Kroah-Hartman4-3/+31
This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit from Kay Sievers that removed the mount/umount uevents from the kernel. Some older versions of HAL still depend on these events to detect when a new device has been mounted. These events are not correctly emitted, and are broken by design, and so, should not be relied upon by any future program. Instead, the /proc/mounts file should be polled to properly detect this kind of event. A feature-removal-schedule.txt entry has been added, noting when this interface will be removed from the kernel.

2006-02-21[PATCH] tmpfs: fix mount mpol nodelist parsingHugh Dickins2-21/+81
I've been dissatisfied with the mpol_nodelist mount option which was added to tmpfs earlier in -rc. Replace it by mpol=policy:nodelist. And it was broken: a nodelist is a comma-separated list of numbers and ranges; the mount options are a comma-separated list of token=values. Whoops, blindly strsep'ing on commas doesn't work so well: since we've no numeric tokens, and unlikely to add them, use that to distinguish. Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject all its options as invalid if not NUMA. /proc shows MPOL_PREFERRED as "prefer", so use that name for the policy instead of "preferred". Enforce that mpol=default has no nodelist; that mpol=prefer has one node only; that mpol=bind has a nodelist; but let mpol=interleave use node_online_map if no nodelist given.

2006-02-20[PATCH] m32r: update sys_tas() routineHirokazu Takata1-27/+34
This patch updates and fixes sys_tas() routine for m32r. In the previous implementation, a lockup rarely caused at sys_tas() routine in SMP environment. > > The problem is that touching *addr will generate an oops if that page isn't > > paged in. If we convert it to use get_user() then that's an improvement, > > but we must not run get_user() under spinlock or local_irq_disable(). I rewrote sys_tas() routine by using "lock -> unlock" instructions, and utilizing the m32r's interrupt handling characteristics; the m32r processor can accept interrupts only at the 32-bit instruction boundary. So, the "unlock" instruction can be executed continuously after the "lock" instruction execution without any interruptions. In addition, to solve such a page_fault problem, I use a fixup code like get_user(). And, as for the kernel lockup problem, we found that a calling do_page_fault() routine with disabling interrupts might cause a lockup at flush_tlb_others(), because we checked a completion of IPI handler's operations in a spin-locked critical section. Therefore, by using "lock -> unlock" code, we can implement the sys_tas() rouitine without disabling interrupts explicitly, then no lockups would happen at flush_tlb_others(), I hope. Compile check and some working test in SMP environment have done.
