2008-07-27sparc, sparc64: use arch/sparc/includeSam Ravnborg
The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build.

2008-07-27missing bits of net-namespace / sysctlAl Viro
Piss-poor sysctl registration API strikes again, film at 11... What we really need is _pathname_ required to be present in already registered table, so that kernel could warn about bad order. That's the next target for sysctl stuff (and generally saner and more explicit order of initialization of ipv[46] internals wouldn't hurt either). For the time being, here are full fixups required by ..._rotable() stuff; we make per-net sysctl sets descendents of "ro" one and make sure that sufficient skeleton is there before we start registering per-net sysctls.

2008-07-27[SCSI] extend the last_sector_bug flag to cover more sectorsAlan Jenkins
The last_sector_bug flag was added to work around a bug in certain usb cardreaders, where they would crash if a multiple sector read included the last sector. The original implementation avoids this by e.g. splitting an 8 sector read which includes the last sector into a 7 sector read, and a single sector read for the last sector. The flag is enabled for all USB devices. This revealed a second bug in other usb cardreaders, which crash when they get a multiple sector read which stops 1 sector short of the last sector. Affected hardware includes the Kingston "MobileLite" external USB cardreader and the internal USB cardreader on the Asus EeePC. Extend the last_sector_bug workaround to ensure that any access which touches the last 8 hardware sectors of the device is a single sector long. Requests are shrunk as necessary to meet this constraint. This gives us a safety margin against potential unknown or future bugs affecting multi-sector access to the end of the device. The two known bugs only affect the last 2 sectors. However, they suggest that these devices are prone to fencepost errors and that multi-sector access to the end of the device is not well tested. Popular OS's use multi-sector accesses, but they rarely read the last few sectors. Linux (with udev & vol_id) automatically reads sectors from the end of the device on insertion. It is assumed that single sector accesses are more thoroughly tested during development.

2008-07-27avr32: some mmc/sd cleanupsDavid Brownell
Minor cleanups for the MMC/SD support on avr32: - Make at32_add_device_mci() properly initialize "missing" platform data ... so boards like STK1002 won't try GPIO 0. - Switch over to gpio_is_valid() instead of testing for only one designated value. - Provide STK1002 platform data for the unlikely case that switches are set so first Ethernet controller isn't in use. (That's the only way to get card detect and writeprotect switch sensing on the STK1000.) And get rid of one "unused variable" warning.

2008-07-27[ARM] Fix shared mmap when more than two maps of the same file existRussell King
The shared mmap code works fine for the test case, which only checked for two shared maps of the same file. However, three shared maps result in one mapping remaining cached, resulting in stale data being visible via that mapping. Fix this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-07-27[ARM] fix VIPT/VIVT macro optimisations, add commentsRussell King
cacheflush.h was doing: ... VIVT only stuff ... VIPT only stuff ... VIVT or VIPT stuff which is clearly bogus - we would only ever use the "VIVT or VIPT" case when both VIVT and VIPT are not selected. Fix this. Add comments to each case, including noting the impossibility of correctly detecting the cache type of ARM926 and ARMv6 cores from the cache type register in the "VIVT or VIPT" case.

2008-07-27KVM: s390: Fix possible host kernel bug on lctl(g) handlingChristian Borntraeger
The lctl(g) instructions require a specific alignment for the parameters. The architecture requires a specification program check if these alignments are not used. Enforcing this alignment also removes a possible host BUG, since the get_guest functions check for proper alignment and emits a BUG.

2008-07-27KVM: s390: Fix program check on interrupt delivery handlingChristian Borntraeger
The current interrupt handling on s390 misbehaves on an error case. On s390 each cpu has the prefix area (lowcore) for interrupt delivery. This memory must always be available. If we fail to access the prefix area for a guest on interrupt delivery the configuration is completely unusable. There is no point in sending another program interrupt to an inaccessible lowcore. Furthermore, we should not bug the host kernel, because this can be triggered by userspace. I think the guest kernel itself can not trigger the problem, as SET PREFIX and SIGNAL PROCESSOR SET PREFIX both check that the memory is available and sane. As this is a userspace bug (e.g. setting the wrong guest offset, unmapping guest memory) we should kill the userspace process instead of BUGing the host kernel. In the long term we probably should notify the userspace process about this problem. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
