attribute_group are not supposed to change at runtime. All functions working with attribute_group provided by <linux/sysfs.h> work with const attribute_group. So mark the non-const structs as const. Signed-off-by:

Add const to bin_attribute structures as they are only passed to the functions sysfs_{remove/create}_bin_file. The arguments passed are of type const, so declare the structures to be const.

eeprom_93xx46_platform_data struct has a 'struct gpio_desc' type member, so it is better to include <linux/gpio/consumer.h>, which provides 'struct gpio_desc' type. Signed-off-by:

Commit 3ca9b1ac ("misc: eeprom_93xx46: Add support for a GPIO 'select' line.") introduced the optional usage of 'select-gpios' by using the gpiod API in a convoluted way. Rewrite the gpiod handling to make the code simpler. Signed-off-by:

Hold on to the pages allocated and mapped for transaction buffers until the system is under memory pressure. When that happens, use linux shrinker to free pages. Without using shrinker, patch "android: binder: Move buffer out of area shared with user space" will cause a significant slow down for small transactions that fit into the first page because free list buffer header used to be inlined with buffer data. In addition to prevent the performance regression for small transactions, this patch improves the performance for transactions that take up more than one page. Modify alloc selftest to work with the shrinker change. Test: Run memory intensive applications (Chrome and Camera) to trigger shrinker callbacks. Binder frees memory as expected. Test: Run binderThroughputTest with high memory pressure option enabled. Signed-off-by:

Binder driver allocates buffer meta data in a region that is mapped in user space. These meta data contain pointers in the kernel. This patch allocates buffer meta data on the kernel heap that is not mapped in user space, and uses a pointer to refer to the data mapped. Signed-off-by:

binder_alloc_selftest tests that alloc_new_buf handles page allocation and deallocation properly when allocate and free buffers. The test allocates 5 buffers of various sizes to cover all possible page alignment cases, and frees the buffers using a list of exhaustive freeing order. Test: boot the device with ANDROID_BINDER_IPC_SELFTEST config option enabled. Allocator selftest passes. Signed-off-by:

This gave us more freedom to change/add/remove operations without recompiling all device driver. Typically, Carrier board implement the fmc operations, so they will not use these helpers. Signed-off-by:

There is a mistake here where we accidentally use sizeof(TB_CFG_PKG_RESET) instead of just TB_CFG_PKG_RESET. The size of an int is 4 so it's the same as TB_CFG_PKG_NOTIFY_ACK. Fixes: d7f781bf ("thunderbolt: Rework control channel to be more reliable") Reported-by:

If secure authentication of a devices fails, either because the device already has another key uploaded, or there is some other error sending challenge to the device, and the user only wants to approve the device just once (without a new key being uploaded to the device) the current implementation does not allow this because the key cannot be cleared once set even if we allow it to be changed. Make this scenario possible and allow clearing the key by writing empty string to the key sysfs file. Signed-off-by:

Also, we were passing a drvdata pointer to the coresight_timeout() function, but we really wanted to pass the address of the register base. Luckily the base is the first member of the structure, so everything works out, but this is quite unsafe if we ever change the structure layout. Clean this all up so sparse stops complaining on this code. Reported-by:

Suzuki K Poulose authored
The coresight SoC 600 supports ETR save-restore which allows us to restore a trace session by retaining the RRP/RWP/STS.Full values when the TMC leaves the Disabled state. However, the TMC doesn't have a scatter-gather unit in built. Also, TMCs have different PIDs in different configurations (ETF, ETB & ETR), unlike the previous generation. While the DEVID exposes some of the features/changes in the TMC, it doesn't explicitly advertises the new save-restore feature as described above.
