* powerpc: Add missing reference to coherent_dma_maskVitaly Bordug2008-07-09
| | | | | | | | | | There is dma_mask in of_device upon of_platform_device_create() but we don't actually set coherent_dma_mask. This may cause weird behavior of USB subsystem using of_device USB host drivers.

* powerpc: Fix unterminated of_device_id array in legacy_serial.cBenjamin Herrenschmidt2008-07-07
| | | | | | | | | | | | A recent patch to legacy_serial.c factored out some code by using the of_match_node() facility to match a node against an array of possible matches. However, the patch didn't properly terminate the array causing potential crashes in cases where no match is found. In addition, the name of the array was poorly chosen for a static symbol making debugging harder.

| * powerpc/mpc5200: Fix lite5200b suspend/resumeTim Yamin2008-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Suspend/resume ("echo mem > /sys/power/state") does not work with vanilla kernels -- the system does not suspend correctly and just hangs. This patch fixes this so suspend/resume works: 1) of_iomap does not map the whole 0xC000 of the MPC5200 immr so saving registers does not work. 2) PCI registers need to be saved and restored.

* Reinstate ZERO_PAGE optimization in 'get_user_pages()' and fix XIPLinus Torvalds2008-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | KAMEZAWA Hiroyuki and Oleg Nesterov point out that since the commit 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") removed the ZERO_PAGE from the VM mappings, any users of get_user_pages() will generally now populate the VM with real empty pages needlessly. We used to get the ZERO_PAGE when we did the "handle_mm_fault()", but since fault handling no longer uses ZERO_PAGE for new anonymous pages, we now need to handle that special case in follow_page() instead. In particular, the removal of ZERO_PAGE effectively removed the core file writing optimization where we would skip writing pages that had not been populated at all, and increased memory pressure a lot by allocating all those useless newly zeroed pages. This reinstates the optimization by making the unmapped PTE case the same as for a non-existent page table, which already did this correctly. While at it, this also fixes the XIP case for follow_page(), where the caller could not differentiate between the case of a page that simply could not be used (because it had no "struct page" associated with it) and a page that just wasn't mapped. We do that by simply returning an error pointer for pages that could not be turned into a "struct page *". The error is arbitrarily picked to be EFAULT, since that was what get_user_pages() already used for the equivalent IO-mapped page case. [ Also removed an impossible test for pte_offset_map_lock() failing: that's not how that function works ] Acked-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: Nick Piggin <npiggin@suse.de> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Hugh Dickins <hugh@veritas.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Roland McGrath <roland@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* [POWERPC] Clear sub-page HPTE present bits when demoting page sizePaul Mackerras2008-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | When we demote a slice from 64k to 4k, and we are about to insert an HPTE for a 4k subpage and we notice that there is an existing 64k HPTE, we first invalidate that HPTE before inserting the new 4k subpage HPTE. Since the bits that encode which hash bucket the old HPTE was in overlap with the bits that encode which of the 16 subpages have HPTEs, we need to clear out the subpage HPTE-present bits before starting to insert HPTEs for the 4k subpages. If we don't do that, we can erroneously think that a subpage already has an HPTE when it doesn't. That in itself wouldn't be such a problem except that when we go to update the HPTE that we think is present on machines with a hypervisor, the hypervisor can tell us that the HPTE we think is there is actually there even though it isn't, which can lead to a process getting stuck in a loop, continually faulting. The reason for the confusion is that the AVPN (abbreviated virtual page number) we are looking for in the HPTE for a 4k subpage can actually match the AVPN in a stale HPTE for another 64k page. For example, the HPTE for the 4k subpage at 0x84000f000 will be in the same hash bucket and have the same AVPN as the HPTE for the 64k page at 0x8400f0000. This fixes the code to clear out the subpage HPTE-present bits. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Turn on ATA_SFF so we get SATA_SVW back in defconfigsPaul Mackerras2008-06-16
| | | | | | | | | | This enables CONFIG_ATA_SFF in the defconfigs that are intended to work on a G5 powermac, i.e. g5_defconfig and ppc64_defconfig. Since the support for the SATA cell in the K2 chipset is provided by the sata_svw.c driver, and that depends on CONFIG_ATA_SFF, we need to turn that and CONFIG_SATA_SVW back on so we can get to the hard disk on G5s.

* [POWERPC] Fix -Os kernel builds with newer gcc versionsKumar Gala2008-06-16
| | | | | | | | | | | | | | | | | | | | | GCC 4.4.x looks to be adding support for generating out-of-line register saves/restores based on: http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html This breaks the kernel if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE. To fix this we add the use the save/restore code from gcc and simplified it down for our needs (integer only). Additionally, we have to link this code into each module. The other solution was to add EXPORT_SYMBOL() which meant going through the trampoline which seemed nonsensical for these out-of-line routines. Finally, we add some checks to prom_init_check.sh to ignore the out-of-line save/restore functions.

|/ | | | | | | | | | | | | | | | Change the name of the device from "rtc-ds1374" to just "ds1374", to match what all other RTC drivers do. I seem to remember that this name was chosen to avoid possible confusion with an older ds1374 driver, but that driver was removed 3 months ago.

| | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Add kernstart_addr to list of allowed symbols in prom_initMichael Ellerman2008-05-23
| | | | | | | | | | | | | | | Since commit "85xx: Add support for relocatable kernel (and booting at non-zero)" (37dd2badcfcec35f5e21a0926968d77a404f03c3), PHYSICAL_START is #defined as kernstart_addr if RELOCATABLE and FLATMEM is enabled. PHYSICAL_START is used in prom_init.c and so kernstart_addr needs to be added to the list of allowed symbols that prom_init.c can access.

* [POWERPC] PS3: Fix memory hotplugGeoff Levand2008-05-23
| | | | | | | | | | | | | | | A change was made to walk_memory_resource() in commit 4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a check of find_lmb(). Add the coresponding lmb_add() call to ps3_mm_add_memory() so that that check will succeed. This fixes the condition where the PS3 boots up with only the 128 MiB of boot memory, and doesn't see the other 128MiB that is available.
