2006-09-21[POWERPC] EEH: balance pcidev_get/put callsLinas Vepstas
This corrects a pci_dev get/put imbalance that can occur only in highly unlikely situations (kmalloc failures, pci devices with overlapping resource addresses). No actual failures seen, this was spotted during code review. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-09-21[POWERPC] PPC: Fix xmon stack frame address in backtraceJosh Boyer
The stack frame address was being printed incorrectly in the backtrace option of XMON on PPC. This patch fixes it to print the actual stack address instead of the address of the local variable that contains it.

2006-09-21[POWERPC] Add AT_PLATFORM value for Xilinx Virtex-4 FXPeter Bergner
Jakub noticed the cputable.c entry for Xilinx Virtex-4 FX was missing a .platform value, so the AT_PLATFORM value wouldn't be set correctly. This adds it. Signed-off-by: Peter Bergner <bergner@vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-09-21Fix 'make headers_check' on shPaul Mundt
Cleanup for user headers, as noted: asm-sh/page.h requires asm-generic/memory_model.h, which does not exist in exported headers asm-sh/ptrace.h requires asm/ubc.h, which does not exist in exported headers Signed-off-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-09-21[CRYPTO] drivers: Remove obsolete block cipher operationsHerbert Xu
This patch removes obsolete block operations of the simple cipher type from drivers. These were preserved so that existing users can make a smooth transition. Now that the transition is complete, they are no longer needed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] s390: Added block cipher versions of CBC/ECBHerbert Xu
This patch adds block cipher algorithms for S390. Once all users of the old cipher type have been converted the existing CBC/ECB non-block cipher operations will be removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] s390: Added missing driver name and priorityHerbert Xu
Accelerated versions of crypto algorithms must carry a distinct driver name and priority in order to distinguish themselves from their generic counter- part. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Get rid of flags argument to setkeyHerbert Xu
Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2006-09-20[S390] hypfs crashes with invalid mount option.Michael Holzheu
When an invalid mount option is specified, no root inode is created for hypfs, hypfs_fill_super() returns with -EINVAL and then hypfs_kill_super() is called. hypfs_kill_super() does not check if the root inode has been initialized. This patch adds this check. Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Fix compile warning with some configurations: arch/s390/mm/cmm.c:58: warning: 'cmm_strtoul' defined but not used Originally cmm_strtoul was introduced because simple_strtoul couldn't handle strings with hexadecimal numbers that contained a capital 'X'.

2006-09-20[S390] fix syscall restart handling.Heiko Carstens
If do_signal() gets called several times before returning to user space and no signal is pending (e.g. cancelled by a debugger) syscall restart handling could be done several times. This would change the user space PSW to an address prior to the syscall instruction. Fix this by making sure that syscall restart handling is only done once.

2006-09-20[S390] initrd vs. bootmem bitmap.Heiko Carstens
Move initrd if the bitmap of the bootmem allocator would overwrite it. In addition this patch sets the default size and address of the initrd to 0. Therefore all boot loaders must set the initrd size and address correctly. This is especially relevant for ftp boot via HMC/SE, where this change requires a special patch file entry in the .ins file which sets these two values contained at address 0x10408 and 0x10410.

2006-09-20[ARM] 3759/2: Remove uses of %?Daniel Jacobowitz
Patch from Daniel Jacobowitz The ARM kernel has several uses of asm("foo%?"). %? is a GCC internal modifier used to output conditional execution predicates. However, no version of GCC supports conditionalizing asm statements. GCC 4.2 will correctly expand %? to the empty string in user asms. Earlier versions may reuse the condition from the previous instruction. In 'if (foo) asm ("bar%?");' this is somewhat likely to be right... but not reliable. So, the only safe thing to do is to remove the uses of %?. I believe the tlbflush.h occurances were supposed to be removed before, based on the comment about %? not working at the top of that file. Old versions of GCC could omit branches around user asms if the asm didn't mark the condition codes as clobbered. This problem hasn't been seen on any recent (3.x or 4.x) GCC, but it could theoretically happen. So, where %? was removed a cc clobber was added.

2006-09-20[POWERPC] Start arch/powerpc/boot code reorganizationMark A. Greer
This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-09-20[POWERPC] Define of_read_ulong helperPaul Mackerras
There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.

2006-09-19Revert mmiocfg heuristics and blacklist changesLinus Torvalds
This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and 40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.
