The only real user of this file outside platforms/iseries was drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR() so we move that to abs_addr.h (and lowercase it). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-10-12ppc64: Remove duplicate versions of some headersPaul Mackerras3-386/+0
This removes three headers from include/asm-ppc64 that are now in include/asm-powerpc and are sufficiently similar that they can be used with ARCH=ppc64. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-11ppc: Various minor compile fixesPaul Mackerras2-0/+7
This fixes up a variety of minor problems in compiling with ARCH=ppc arising from using the merged versions of various header files. A lot of the changes are just adding #include <asm/machdep.h> to files that use ppc_md or smp_ops_t. This also arranges for us to use semaphore.c, vecemu.c, vector.S and fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-10[PATCH] x86_64: Allocate cpu local data for all possible CPUsAndi Kleen1-0/+1
CPU hotplug fills up the possible map to NR_CPUs, but it did that after setting up per CPU data. This lead to CPU data not getting allocated for all possible CPUs, which lead to various side effects. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-10[PATCH] Fix signal sending in usbdevio on async URB completionHarald Welte1-0/+1
If a process issues an URB from userspace and (starts to) terminate before the URB comes back, we run into the issue described above. This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.

2005-10-10[PATCH] x86_64: Set up safe page tables during resumeRafael J. Wysocki1-0/+2
The following patch makes swsusp avoid the possible temporary corruption of page translation tables during resume on x86-64. This is achieved by creating a copy of the relevant page tables that will not be modified by swsusp and can be safely used by it on resume. The problem is that during resume on x86-64 swsusp may temporarily corrupt the page tables used for the direct mapping of RAM. If that happens, a page fault occurs and cannot be handled properly, which leads to the solid hang of the affected system. This leads to the loss of the system's state from before suspend and may result in the loss of data or the corruption of filesystems, so it is a serious issue. Also, it appears to happen quite often (for me, as often as 50% of the time). The problem is related to the fact that (at least) one of the PMD entries used in the direct memory mapping (starting at PAGE_OFFSET) points to a page table the physical address of which is much greater than the physical address of the PMD entry itself. Moreover, unfortunately, the physical address of the page table before suspend (i.e. the one stored in the suspend image) happens to be different to the physical address of the corresponding page table used during resume (i.e. the one that is valid right before swsusp_arch_resume() in arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is restored, the "offending" PMD entry gets overwritten, so it does not point to the right physical address any more (i.e. there's no page table at the address pointed to by it, because it points to the address the page table has been at during suspend). Consequently, if the PMD entry is used later on, and it _is_ used in the process of copying the image pages, a page fault occurs, but it cannot be handled in the normal way and the system hangs. In principle we can call create_resume_mapping() from swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory allocations in create_resume_mapping(), resume_pud_mapping(), and resume_pmd_mapping() must be made carefully so that we use _only_ NosaveFree pages in them (the other pages are overwritten by the loop in swsusp_arch_resume()). Additionally, we are in atomic context at that time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations fails, we should free all of the allocated pages, so we need to trace them somehow. All of this is done in the appended patch, except that the functions populating the page tables are located in arch/x86_64/kernel/suspend.c rather than in init.c. It may be done in a more elegan way in the future, with the help of some swsusp patches that are in the works now. [AK: move some externs into headers, renamed a function] Signed-off-by: Rafael J.

2005-10-06powerpc: Merge lmb.c and make MM initialization use it.Paul Mackerras1-7/+11
This also creates merged versions of do_init_bootmem, paging_init and mem_init and moves them to arch/powerpc/mm/mem.c. It gets rid of the mem_pieces stuff. I made memory_limit a parameter to lmb_enforce_memory_limit rather than a global referenced by that function.

2005-10-06powerpc: Merge in the ppc64 version of the prom code.Paul Mackerras7-0/+690
This brings in the ppc64 version of prom_init.c, prom.c and btext.c and makes them work for ppc32. This also brings in the new calling convention, where the first entry to the kernel (with r5 != 0) goes to the prom_init code, which then restarts from the beginning (with r5 == 0) after it has done its stuff. For now this also brings in the ppc32 version of setup.c. It also merges lmb.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
