* UML: Fix compiler warning due to missing task_struct declarationJan Kiszka2010-04-212-0/+4
| | | | | | | | | | | | | | | | | | | We can't pull in linux/sched.h due to circular dependency, so just forward-declare the struct. This fixes the following warning: CC arch/um/sys-i386/elfcore.o In file included from /data/linux-2.6/include/linux/elf.h:8, from /data/linux-2.6/arch/um/sys-i386/elfcore.c:2: arch/um/sys-i386/asm/elf.h:78: warning: ‘struct task_struct’ declared inside parameter list arch/um/sys-i386/asm/elf.h:78: warning: its scope is only this definition or declaration, which is probably not what you want I guess not many people build against i386 hosts anymore, so this remained widely unnoticed.

* UML: add kernel.h include to signal.cJiri Kosina2010-04-201-0/+1
| | | | | | | | | | | Commit 814f75ec5a94a48 ("UML: Drop private round_down definition") dropped the private round_down() macro and makes signal.c use the one from kernel.h instead. kernel.h is implicitly included through uaccess.h -> sched.h -> kernel.h but we'd rather make this dependency explicit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 5fb4d38b19d95a5f980f0a10adba798f5b92128c ("mfd: Move WM831x to generic IRQ") didn't take into account that genirq support depends on GENERIC_HARDIRQS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After d_find_alias(), vfat_lookup() checks !(->d_flags & DCACHE_DISCONNECTED) without IS_ROOT(). This means it hits non-anonymous but disconnected dentry. (NOTE: d_splice_alias() doesn't clear DCACHE_DISCONNECTED) But, vfat_lookup() has interest to alias if it was non-anonymous. So, this adds vfat_d_anon_disconn() helper to check it correctly. Another bug is refcnt leak. It needs dput() for uninterested alias. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the gitignore file patters were explicitly meant to be only for the top level, but weren't marked that way, so they would trigger recursively in subdirectories too. Normally that was harmless, but at least "linux" happened to trigger elsewhere too. Fix it up. And other patterns in that section weren't necessarily top-level at all.

After looking at the anon_inode and its users it looks like the best solution is to just mark the anon_inode as S_PRIVATE so the security system will ignore it.

The handling of breakpoints and watchpoints is inconsistent. When a breakpoint or watchpoint is hit, the interrupt handler is clearing the proper bits in the dbcr* registers, but leaving the dac* and iac* registers alone. The ptrace code to delete the break/watchpoints checks the dac* and iac* registers for zero to determine if they are enabled. Instead, they should check the dbcr* bits.

This is needed because the Partition Adjunct Option of new versions of pHyp extend the H_XIRR hcall to include the CPPR as an input parameter. Earlier versions not supporting this option just disregard the extra input parameter, so this doesn't cause any problems for existing systems. The Partition Adjunct Option is required for future systems that will support SR-IOV capable devices.
