The Asus WL520GC and WL520GU are based on the BCM5354 and clocked at 200MHz, but they do not have a clkfreq nvram variable set to the correct value. This adds a workaround for these devices. Signed-off-by:

Some BCM5354 SoCs are running at 200MHz, but it is not possible to read the clock from a register like it is done on some other SoC in ssb and bcma. These devices should have a clkfreq nvram configuration value set to 200, read it and set the clock to the correct value. Signed-off-by:

Helge Deller authored
Since the beginning of the parisc-linux port, sometimes 64bit SMP kernels were not able to bring up other CPUs than the monarch CPU and instead crashed the kernel. The reason was unclear, esp. since it involved various machines (e.g. J5600, J6750 and SuperDome). Testing showed, that those crashes didn't happened when less than 4GB were installed, or if a 32bit Linux kernel was booted. In the end, the fix for those SMP problems is trivial: During the early phase of the initialization of the CPUs, including the monarch CPU, the PDC_PSW firmware function to enable WIDE (=64bit) mode is called. It's documented that this firmware function may clobber various registers, and one one of those possibly clobbered registers is %cr30 which holds the task thread info pointer. Now, if %cr30 would always have been clobbered, then this bug would have been detected much earlier. But lots of testing finally showed, that - at least for %cr30 - on some machines only the upper 32bits of the 64bit register suddenly turned zero after the firmware call. So, after finding the root cause, the explanation for the various crashes became clear: - On 32bit SMP Linux kernels all upper 32bit were zero, so we didn't faced this problem. - Monarch CPUs in 64bit mode always booted sucessfully, because the inital task thread info pointer was below 4GB. - Secondary CPUs booted sucessfully on machines with less than 4GB RAM because the upper 32bit were zero anyay. - Secondary CPus failed to boot if we had more than 4GB RAM and the task thread info pointer was located above the 4GB boundary. Finally, the patch to fix this problem is trivial by saving the %cr30 register before the firmware call and restoring it afterwards. Signed-off-by:

This patch addresses a long-standing bug where the get_user_pages_fast() write parameter used for setting the underlying page table entry permission bits was incorrectly set to write=1 for data_direction=DMA_TO_DEVICE, and passed into get_user_pages_fast() via vhost_scsi_map_iov_to_sgl(). However, this parameter is intended to signal WRITEs to pinned userspace PTEs for the virtio-scsi DMA_FROM_DEVICE -> READ payload case, and *not* for the virtio-scsi DMA_TO_DEVICE -> WRITE payload case. This bug would manifest itself as random process segmentation faults on KVM host after repeated vhost starts + stops and/or with lots of vhost endpoints + LUNs.

The "legacy" ECC layout used until 3.12-rc1 uses all the OOB area by computing the ECC strength and ECC step size ourselves. Commit 2febcdf8 ("mtd: gpmi: set the BCHs geometry with the ecc info") makes the driver use the ECC info (ECC strength and ECC step size) provided by the MTD code, and creates a different NAND ECC layout for the BCH, and use the new ECC layout. This causes a regression: We can not mount the ubifs which was created by the old NAND ECC layout. This patch fixes this issue by reverting to the legacy ECC layout. We will probably introduce a new device-tree property to indicate that the new ECC layout can be used. For now though, for the imminent 3.12 release, we just unconditionally revert to the 3.11 behaviour. This leaves a harmless cosmetic warning about an unused function. At this point in the cycle I really don't care. Signed-off-by:

This issue was first pointed out by Jiaxing Wang several months ago, but no further comments: https://lkml.org/lkml/2013/6/29/41 As we know pread() does not change f_pos, so after pread(), file->f_pos and m->read_pos become different. And seq_lseek() does not update file->f_pos if offset equals to m->read_pos, so after pread() and seq_lseek()(lseek to m->read_pos), then a subsequent read may read from a wrong position, the following program produces the problem: char str1[32] = { 0 }; char str2[32] = { 0 }; int poffset = 10; int count = 20; /*open any seq file*/ int fd = open("/proc/modules", O_RDONLY); pread(fd, str1, count, poffset); printf("pread:%s\n", str1); /*seek to where m->read_pos is*/ lseek(fd, poffset+count, SEEK_SET); /*supposed to read from poffset+count, but this read from position 0*/ read(fd, str2, count); printf("read:%s\n", str2); out put: pread: ck_netbios_ns 12665 read: nf_conntrack_netbios /proc/modules: nf_conntrack_netbios_ns 12665 0 - Live 0xffffffffa038b000 nf_conntrack_broadcast 12589 1 nf_conntrack_netbios_ns, Live 0xffffffffa0386000 So we always update file->f_pos to offset in seq_lseek() to fix this issue.

Instead use the provided by the platform_device. The MTD name was changed to use the one provided by the platform_device. However, this can be problematic as some users want to set partitions using the kernel parameter 'mtdparts', where the name is needed. Therefore, to avoid regressions in users relying in 'mtdparts' we revert the change and use the previous one 'pxa3xx_nand-0'. While at it, let's put a big comment and prevent this change from happening ever again. Signed-off-by:
