If the page is not mapped into any process's address space then aliases cannot exist in the cache. So reduce the amount of flushing we perform. Signed-off-by:Matt Fleming <matt@console-pimps.org>

The previous expressions were wrong which made free_pmd_range() explode when using anything other than 4KB pages (which is why 8KB and 64KB pages were disabled with the 3-level page table layout). The problem was that pmd_offset() was returning an index of non-zero when it should have been returning 0. This non-zero offset was used to calculate the address of the pmd table to free in free_pmd_range(), which ended up trying to free an object that was not aligned on a page boundary. Now 3-level page tables should work with 4KB, 8KB and 64KB pages. Signed-off-by:

With some of the cache rework an address aliasing optimization was added, but this managed to fail on certain mappings resulting in pages with PG_dcache_dirty set never writing back their dcache lines. This patch reverts to the earlier behaviour of simply always writing back when the dirty bit is set. Signed-off-by:

ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard API that accomplishes the same thing. As such, this converts the remaining sh-sci straggles over, which enables the driver to be wired up for ARM SH-Mobile CPUs as well. Signed-off-by: -

This reverts commit 9f15226e. It's just wrong, and broke resume for Rafael even on a non-AMD CPU. As Rafael says: "... it causes microcode_init_cpu() to be called during resume even for CPUs for which there's no microcode to apply. That, in turn, results in executing request_firmware() (on Intel CPUs at least) which doesn't work at this stage of resume (we have device interrupts disabled, I/O devices are still suspended and so on). If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is known to us" , so before commit 9f15226e microcode_resume_cpu() was called for all CPUs already in the system during suspend, which was the right thing to do. The commit changed it so that the CPUs without microcode to apply are now treated as "unknown", which is not quite right. The problem this commit attempted to solve has to be handled differently."

brightness status is reported by the Apple Cinema Displays as an 'unsigned char' (u8) value, but the code used 'char' instead. Note that he driver was developed on the PowerPC architecture, where the two types are synonymous, which is not always the case. Fixed that. Otherwise the driver will interpret brightness levels > 127 as negative, and fail to load. Signed-off-by:

This patch fixes the below array index out of bounds issue. Buffer overflow, array index of 'aInfo' may be out of bounds. Array 'aInfo' of size 78 may use index value(s) 6..84 The data stored in 'aInfo' array exceeds the array size of 78. This patch increases the size of this array to hold the string correctly without any memory corruption. This issue was reported by Klockwork tool. Signed-off-by:

Race condition exists between the cppi_interrupt handler and davinci_interrupt handler w.r.t completing a TX IO. Since DM646x has seperate DMA and USB endpoint interrupts cppi_interrupt handler needs to hold the lock while operating on the endpoint. Update over previous patch to avoid taking the lock if already taken. Tested on DM644x, DM355 and DM646x platforms. Signed-off-by:

This is a (almost) sort-only patch to sort FTDI device product ID definitions in new ftdi_sio_ids.h header. Advantage is that new device ID submissions will now have a specific (sorted) position - less future merge conflicts. Compile-tested, based on _current_ mainline git. Minor checkpatch.pl warnings were eliminated whereever it made sense, very minor text changes. Signed-off-by:

This is a strictly move-only patch to relocate all FTDI device product ID definitions to their own ftdi_sio_ids.h header (following the usual *_ids.h kernel tree convention, too), thus correcting the slightly too messy appearance (crucial driver defines were stuck somewhere in the decaying middle swamp of the huge existing header). Compile-tested, based on latest mainline git. Signed-off-by:

While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).
