2009-12-01MIPS: Loongson: Switch from flatmem to sparsememWu Zhangjin
With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. The config help of sparsemem says: "This option provides some potential performance benefits, along with decreased code complexity." So to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.

2009-12-01MIPS: Loongson: Disallow 4kB pagesWu Zhangjin
Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.

Some Debian users have reported that the kernel hangs early during boot on some IP22 systems.

Since there's no fix yet, disable CONFIG_EARLY_PRINTK for now.

2009-11-30Alpha: Rearrange thread info flags fixing two regressionsMichael Cree
The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b "remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect setting of the unaligned access control flags by the prctl syscall. The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]" further caused problems, namely incorrect operands to assembler code as evidenced by: AS arch/alpha/kernel/entry.o arch/alpha/kernel/entry.S: Assembler messages: arch/alpha/kernel/entry.S:326: Warning: operand out of range (0x0000000000000406 is not between 0x0000000000000000 and 0x00000000000000ff) Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be in lower 8 bits of the thread info flags, and (2) making sure that ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.

Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend and resume process, but don't clean up after themselves.

Now Linux should be able to work regardless of any laziness on the part of the on-chip ROM or boot loader.

2009-11-24[CPUFREQ] Enable ACPI PDC handshake for VIA/Centaur CPUsHarald Welte
In commit 0de51088e6a82bc8413d3ca9e28bbca2788b5b53, we introduced the use of acpi-cpufreq on VIA/Centaur CPU's by removing a vendor check for VENDOR_INTEL. However, as it turns out, at least the Nano CPU's also need the PDC (processor driver capabilities) handshake in order to activate the methods required for acpi-cpufreq. Since arch_acpi_processor_init_pdc() contains another vendor check for Intel, the PDC is not initialized on VIA CPU's. The resulting behavior of a current mainline kernel on such systems is: acpi-cpufreq loads and it indicates CPU frequency changes. However, the CPU stays at a single frequency This trivial patch ensures that init_intel_pdc() is called on Intel and VIA/Centaur CPU's alike.

2009-11-23sparc64: Fix definition of VMEMMAP_SIZE.David S. Miller
This was the cause of various boot failures on V480, V880, etc. systems. Kernel image memory was being overwritten because the vmemmap[] array was being sized to small. So if you had physical memory addresses past a certain point, the early bootup would spam all over variables in the kernel data section. The vmemmap mappings map page structs, not page struct pointers. And that was the key thinko in the macro definition. This was fixable thanks to the help, reports, and tireless patience of Hermann Lauer. Reported-by: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de> Signed-off-by: David S.
