2013-04-23b43: HT-PHY: tables: don't duplicate core-generic regsRafał Miłecki
Now when we know many radio regs at 0x000 are core-generic, I've noticed we duplicate some values in the tables. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
2013-04-23b43: HT-PHY: rename defines addressing cores on the 2059 radioRafał Miłecki
After comparing writes to registers at 0x000, 0x400 and 0x800 it seems there are many very similar writes. So 0x000 offset is not for accessing something totally different, but probably just the first out of three cores. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

2013-04-23pwm: lpc32xx: Properly set PWM_ENABLE bit in lpc32xx_pwm_[enable|disable]Axel Lin
According to the LPC32x0 User Manual [1]: For both PWM1 and PWM2 Control Registers: BIT 31: This bit gates the PWM_CLK signal and enables the external output pin to the PWM_PIN_STATE logical level. 0 = PWM disabled. (Default) 1 = PWM enabled So in lpc32xx_pwm_enable(), we should set PWM_ENABLE bit. In lpc32xx_pwm_disable(), we should just clear PWM_ENABLE bit rather than write 0 to the register which will also clear PWMx_RELOADV and PWMx_DUTY bits.

2013-04-23s390/uapi: change struct statfs[64] member types to unsigned valuesHeiko Carstens
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.

2013-04-23s390/compat: fix compat_sys_statfs() memory corruptionHeiko Carstens

2013-04-23s390/mm,gmap: segment mapping raceMartin Schwidefsky
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>

2013-04-23ipvs: Use network byte order for sync message sizeSimon Horman
struct ip_vs_sync_mesg and ip_vs_sync_mesg_v0 are both sent across the wire and used internally to store IPVS synchronisation messages. Up until now the scheme used has been to convert the size field to network byte order before sending a message on the wire and convert it to host byte order when sending a message. This patch changes that scheme to always treat the field as being network byte order. This seems appropriate as the structure is sent across the wire. And by consistently treating the field has network byte order it is now possible to take advantage of sparse to flag any future miss-use.

2013-04-22VXLAN: Allow L2 redirection with L3 switchingDavid Stevens
Allow L2 redirection when VXLAN L3 switching is enabled This patch restricts L3 switching to destination MAC addresses that are marked as routers in order to allow virtual IP appliances that do L2 redirection to function with VXLAN L3 switching enabled. We use L3 switching on VXLAN networks to avoid extra hops when the nominal router for cross-subnet traffic for a VM is remote and the ultimate destination may be local, or closer to the local node. Currently, the destination IP address takes precedence over the MAC address in all cases. Some network appliances receive packets for a virtualized IP address and redirect by changing the destination MAC address (only) to be the final destination for packet processing. VXLAN tunnel endpoints with L3 switching enabled may then overwrite this destination MAC address based on the packet IP address, resulting in potential loops and, at least, breaking L2 redirections that travel through tunnel endpoints. This patch limits L3 switching to the intended case where the original destination MAC address is a next-hop router and relies on the destination MAC address for all other cases, thus allowing L2 redirection and L3 switching to coexist peacefully.

2013-04-22[media] dib7090p: improve the support of the dib7090 and dib7790Olivier Grenie
The intend of this patch is to improve the support of the dib7090 and dib7790. The AGC1 min value is set to 32768 by default. The actual AGC1 min and the external attenuation are controled depending on the received RF level.

2013-04-22[media] dib8096: enhancementOlivier Grenie
The intend of this patch is to improve the support of the dib8096. The PLL parameters are not automatically computed. The limit to set/unset external diode for attenuation has been updated. The TFE8096P board is using the new I2C API.
