Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into next/fixes-non-critical

Two non critical fixes that can go in 3.11.
* tag 'at91-fixes' of git://github.com/at91linux/linux-at91:
ARM: at91: Change the internal SRAM memory type MT_MEMORY_NONCACHED
ARM: at91: Fix link breakage when !CONFIG_PHYLIB
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
I got a build error today that made me realize that it is not
possible to build a kernel for a SiRF platform without enabling
CONFIG_PRIMA2, since a lot of common code depends on CONFIG_PRIMA2.
This fixes all occurences that appear like common SiRF code.

Because MT_DEVICE is not executable in armv7, we change
the internal SRAM memory type to MT_MEMORY_NONCACHED.
As it seems that caching this internal SRAM memory is not necessary,
we chose the this memory type.

SDI driver gets currently the vdds_sdi regulator via omapdss device.
This is not correct, and we'll change the SDI driver to get the

This patch changes the rx51 board file to add vdds_dsi supply for
omapdss_sdi.0 device.
Note that the vdds_sdi supply for omapdss device is still left there, as
the current display driver uses it. When both the board files and the
display driver has been changed, we can remove the unused supply.

board-cm-t35.c and board-ldp.c contain regulator supply entries for
vdds_dsi. However, the given device name is wrong.
This patch fixes the device name from omapdss_dsi1 to omapdss_dsi.0.
Note that as far as I know, DSI driver is not used on these boards, so
this should not have caused any problems. The DSI block can be used to
generate clock for DPI, though, but that's not enabled for omap3 boards
currently.

If the early MMU mapping of the UART happens to get booted out of the
TLB between the start of paging_init() and when we finally re-add the
UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if
we've got early_printk enabled. Avoid this hang by calling
debug_ll_io_init() early.
Without this patch, you can reliably reproduce a hang when early
printk is enabled by adding flush_tlb_all() at the start of
exynos_init_io(). After this patch the hang goes away.

Merge tag 'renesas-fixes-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes
From Simon Horman, Renesas ARM based SoC fixes for v3.10:
- Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
This avoids conflicts when the USB_OVCn pins are used by another function.
This has been observed to be a problem in v3.10-rc1.
- Update CMT clock rating for sh73a0 SoC to resolve boot failure
on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1.

Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.
Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.
With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

This is an alternative fix to the one sent by Wladislav. We kill the
watchdog for each CPU and then spin in WAIT with interrupts disabled.
This is the lowest power mode for the OCTEON. If we were to spin with
interrupts enabled, we would get a continual stream of warning messages
and backtraces from the lockup detector, so I chose to disable
interrupts.

Since the introduction of preemptible mmu_gather TLB fast mode has been
broken. TLB fast mode relies on there being absolutely no concurrency;
it frees pages first and invalidates TLBs later.
However now we can get concurrency and stuff goes *bang*.
This patch removes all tlb_fast_mode() code; it was found the better
option vs trying to patch the hole by entangling tlb invalidation with
the scheduler.

f9a37be0f0 ("x86: Use PCI setup data") added support for using PCI ROM
images from setup_data. This used phys_to_virt(), which is not valid for
highmem addresses, and can cause a crash when booting a 32-bit kernel via
the EFI boot stub.
pcibios_add_device() assumes that the physical addresses stored in
setup_data are accessible via the direct kernel mapping, and that calling
phys_to_virt() is valid. This isn't guaranteed to be true on x86 where the
direct mapping range is much smaller than on x86-64.
Calling phys_to_virt() on a highmem address results in the following:
BUG: unable to handle kernel paging request at 39a3c198

The solution is to use ioremap() instead of phys_to_virt() to map the
setup data into the kernel address space.

Some ARM KVM VCPU ioctls require the vCPU to be properly initialized
with the KVM_ARM_VCPU_INIT ioctl before being used with further
requests. KVM_RUN checks whether this initialization has been
done, but other ioctls do not.
Namely KVM_GET_REG_LIST will dereference an array with index -1
without initialization and thus leads to a kernel oops.
Fix this by adding checks before executing the ioctl handlers.
