2013-04-26s390/pci: use pci_scan_root_busSebastian Ott1-33/+17

2013-04-26parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updatesJohn David Anglin2-26/+26
User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency.

2013-04-26parisc: disable -mlong-calls compiler option for kernel modulesHelge Deller1-2/+4
CONFIG_MLONGCALLS was introduced in commit ec758f98328da3eb933a25dc7a2eed01ef44d849 to overcome linker issues when linking huge linux kernels, e.g. with many modules linked in. But in the kernel module loader there is no support yet for the new relocation types, which is why modules built with -mlong-calls can't be loaded. Furthermore, for modules long calls are not really necessary, since we already use stub sections which resolve long distance calls. So, let's just disable this compiler option when compiling kernel modules. Signed-off-by: Helge Deller <deller@gmx.de>
2013-04-26parisc: uaccess: fix compiler warnings caused by __put_user castingWill Deacon1-10/+4
When targetting 32-bit processors, __put_user emits a pair of stw instructions for the 8-byte case. If the type of __val is a pointer, the marshalling code casts it to the wider integer type of u64, resulting in the following compiler warnings: kernel/signal.c: In function 'copy_siginfo_to_user': kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] This patch fixes the warnings by removing the marshalling code and using the correct output modifiers in the __put_{user,kernel}_asm64 macros so that GCC will allocate the right registers without the need to extract the two words explicitly.

2013-04-24efi: Check EFI revision in setup_efi_varsJosh Boyer1-1/+1
We need to check the runtime sys_table for the EFI version the firmware specifies instead of just checking for a NULL QueryVariableInfo. Older implementations of EFI don't have QueryVariableInfo but the runtime is a smaller structure, so the pointer to it may be pointing off into garbage. This is apparently the case with several Apple firmwares that support EFI 1.10, and the current check causes them to no longer boot. Fix based on a suggestion from Matthew Garrett.

All of these errors were introduced by recent commits which are in linux-next. f_obex, multi and cdc2 gadget drivers have learned to return a proper error code when something goes wrong. usb_bind_phy() was mistakenly placed into .init.text section which caused Section mismatch warnings and undefined reference compile errors. f_source_sink had a copy-paste error which is now corrected. g_zero got a memory leak plugged. Two defconfigs got fixed to enable the newly introduced CONFIG_USB_PHY.

2013-04-23s390/uapi: change struct statfs[64] member types to unsigned valuesHeiko Carstens2-52/+48
Kay Sievers reported that coreutils' stat tool has a problem with s390's statfs[64] definition: > The definition of struct statfs::f_type needs a fix. s390 is the only > architecture in the kernel that uses an int and expects magic > constants lager than INT_MAX to fit into. > > A fix is needed to make Fedora boot on s390, it currently fails to do > so. Userspace does not want to add code to paper-over this issue. [...] > Even coreutils cannot handle it: > #define RAMFS_MAGIC 0x858458f6 > # stat -f -c%t / > ffffffff858458f6 > > #define BTRFS_SUPER_MAGIC 0x9123683E > # stat -f -c%t /mnt > ffffffff9123683e The bug is caused by an implicit sign extension within the stat tool: out_uint_x (pformat, prefix_len, statfsbuf->f_type); where the format finally will be "%lx". A similar problem can be found in the 'tail' tool. s390 is the only architecture which has an int type f_type member in struct statfs[64]. Other architectures have either unsigned ints or long values, so that the problem doesn't occur there. Therefore change the type of the f_type member to unsigned int, so that we get zero extension instead of sign extension when assignment to a long value happens. This patch changes the s390 uapi struct stafs[64] definition in the kernel to contain only unsigned values. This was true for 32 bit builds anyway, since we use the generic uapi header file in that case. So lets not include conditionally the generic uapi header file but have the s390 implementation completely independent. Also fix the types of struct compat_stafs to match reality and move the definition of struct compat_statfs64 to asm/compat.h since it is not part of the api.

According to Thomas Gleixner's Linux 2.6 history tree this bug is present since v2.5.74 87880da124 "[PATCH] s390: 31 bit compat.". So it get's fixed shortly before its 10th anniversary. Tough luck.

2013-04-23s390/mm,gmap: segment mapping raceMartin Schwidefsky1-69/+91
The gmap_map_segment function creates a special invalid segment table entry with the address of the requested target location in the process address space. The first access will create the connection between the gmap segment table and the target page table of the main process. If two threads do this concurrently both will walk the page tables and allocate a gmap_rmap structure for the same segment table entry. To avoid the race recheck the segment table entry after taking to page table lock. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Manuel Lauss writes: lmo commit c17a6554 (MIPS: page.h: Provide more readable definition for PAGE_MASK) apparently breaks ioremap of 36-bit addresses on my Alchemy systems (PCI and PCMCIA) The reason is that in arch/mips/mm/ioremap.c line 157 (phys_addr &= PAGE_MASK) bits 32-35 are cut off. Seems the new PAGE_MASK is explicitly 32bit, or one could make it signed instead of unsigned long.
