2005-09-14[PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins
Pavel Emelianov and Kirill Korotaev observe that fs and arch users of security_vm_enough_memory tend to forget to vm_unacct_memory when a failure occurs further down (typically in setup_arg_pages variants). These are all users of insert_vm_struct, and that reservation will only be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't. So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into Committed_AS each time they're run. But don't add VM_ACCOUNT to them, it's inappropriate to reserve against the very unlikely case that gdb be used to COW a vDSO page - we ought to do something about that in do_wp_page, but there are yet other inconsistencies to be resolved. The safe and economical way to fix this is to let insert_vm_struct do the security_vm_enough_memory check when it finds VM_ACCOUNT is set. And the MIPS irix_brk has been calling security_vm_enough_memory before calling do_brk which repeats it, doubly accounting and so also leaking. Remove that, and all the fs and arch calls to security_vm_enough_memory: give it a less misleading name later on.

2005-09-13[PATCH] i386: Ignore masked FPU exceptionsChuck Ebbert
Masked FPU exceptions should obviously not happen in the first place, but if they do, ignoring them seems to be the right thing to do. Although there is no documentation available for Cyrix MII, I did find erratum F-7 for Winchip C6, "FPU instruction may result in spurious exception under certain conditions" which seems to indicate that this can happen. That would also explain the behaviour Ondrej Zary reported on the MII. Signed-off-by: Chuck Ebbert <76306.1226@compuserve.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-13[PATCH] ppc64: Make eeh_init function againPaul Mackerras
My patch "Separate pci bits out of struct device_node" (commit 1635317facea3094ddf34082cd86797efb1d9f7e) had the unfortunate side-effect that it stopped eeh_init() from working correctly. It needs the pointers set up by find_and_init_phbs(), but it was being called just before find_and_init_phbs(). That meant that we didn't enable EEH (pSeries PCI error recovery) on any devices, and that meant that on POWER5 systems, the hypervisor wouldn't let us enable memory or I/O space access to any devices, and their drivers got somewhat confused. This fixes it by moving the eeh_init call after find_and_init_phbs. Tested on a POWER5 partition. Signed-of-by: Paul Mackerras <paulus@samba.org> Signed-of-by: Linus Torvalds <torvalds@osdl.org>

Akita Support Add the platform support code for two new Sharp Zaurus Models, Spitz (SL-C3000) and Borzoi (SL-C3100). This patch also adds most of the foundations for Akita (SL-C1000) Support. The missing link for Akita is the driver for its I2C io expander. Once this has been finished, the missing Kconfig option and machine declaration can easily be added to this code.

2005-09-13[PATCH] SharpSL: Add cxx00 support to the Corgi LCD driverRichard Purdie

It also adds some LCD to touchscreen interface logic needed by the touchscreen driver to prevent interference problems, the idea being to keep all the ugly code in one place leaving the drivers themselves clean. sharpsl.h is used to provide the abstraction.

2005-09-13[PATCH] SharpSL: Abstract c7x0 specifics from Corgi SSPRichard Purdie
Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to the c7x0 series yet different. This patch series abstracts the differences and generates a set of common drivers that support both series of devices. It then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100). Hooks for Akita (SL-C1000) differences are also added. The I2C driver for its IO expander is the only missing piece. This patch: Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so that other models such as the cxx00's can share it. Create sharpsl.h which will be used to abstract machine/model specifics. This enables the driver to be used by the Zaurus cxx00 series.
